  • Air Pollution Interactions with Weather and Climate Extremes: Current
           Knowledge, Gaps, and Future Directions

    • Free pre-print version: Loading...

      Abstract: Purpose of Review During the past decade, weather and climate extremes, enhanced by climate change trends, have received tremendous attention because of their significant impacts on socio-economy, public health, and ecosystems. At the same time, many parts of the world still suffer from severe air pollution issues. However, whether and how air pollutants play a role in weather and climate systems through complex interactions and feedbacks with meteorology and ecosystems remains an open question. So far, only a relatively small number of studies have been conducted to understand and quantify air pollution interactions with weather and climate extremes. As a result, there is limited process-level knowledge of this topic and associated mechanisms. This review paper provides a concise synthesis of recent scientific advances, current knowledge gaps, and future directions on air pollution interactions with weather and climate extremes, such as extreme precipitation, floods, droughts, wildfires, and heat waves. Recent Findings There is evidence (albeit limited) that air pollution can contribute to or interact with each of the aforementioned extremes, and several possible mechanisms (e.g., physical, thermodynamical, dynamical, chemical, and ecological processes) have been identified and proposed to explain their relationships. However, there are still substantial knowledge gaps that need to be addressed in future studies, which will benefit from enhanced observational and modeling capabilities as well as interdisciplinary collaborations. Summary Overall, the air pollution interactions with weather and climate extremes are currently under-studied and less understood. More future research is needed for process-level investigations to improve the mechanistic understanding on this topic.

  • A Comprehensive Review on Green and Eco-Friendly Nano-Adsorbents for the
           Removal of Heavy Metal Ions: Synthesis, Adsorption Mechanisms, and
           Applications

    • Free pre-print version: Loading...

      Abstract: Purpose of Review Environmental pollution stemming from industrial, agricultural, and domestic activities is constantly increasing. The removal of these hazardous pollutants from the environment is inevitable, so finding and developing convenient, cost-effective, and biocompatible treatment methods is imperative. As emerging adsorbents, green nanoparticles (NPs) have received significant attention in recent years due to their biocompatibility and promising capability for removing pollutants such as heavy metals from aqueous solutions. This study aims to provide a comprehensive and coherent review of the heavy metals removal via an adsorption technique using green nanoparticles, focusing on their synthesis and adsorption mechanisms. Recent Findings Currently, plants and microorganisms are used to synthesize green nano-adsorbents. The antioxidant compounds in the extracts of different parts of the plants could be used as reducing agents for the synthesis of zero-valent metal nanoparticles. Moreover, they can be applied to the surface of nanoparticles, which enhances the stability of synthesized nanoparticles. In addition to plant-derived compounds, microorganisms can play a significant role in synthesizing green nanoparticles. Summary For decades, human health and the environment have been threatened by exposure to heavy metals caused by the activities of mines, industries, and factories. Therefore, there is a need to provide solutions to remove these pollutants from the environment. One of the effective solutions is the adsorption method. The efficiency of this method is strongly influenced by the selection of suitable adsorbents. In recent years, special attention has been paid to nano-adsorbents. Utilizing green nano-adsorbents, as opposed to conventional materials, is a critical strategy for reducing environmental pollutants, particularly for heavy metal adsorption from contaminated water and wastewater. This paper also discusses the sources and occurrence of heavy metals, as well as a number of environmental issues of methods that employ green and eco-friendly nano-adsorbents for heavy metals removal, including (i) the type of heavy metals and their use pattern, (ii) influencing factors, (iii) heavy metal analysis methods and their potential toxicity, and (iv) different conventional and cutting-edge nanotechnologies for water and wastewater treatment. The literature review, which covered the years 2002–2023, provided a critical illustration of current concerns about heavy metal contamination and removal efforts, with a focus on green nano-adsorbents and the use of these environmentally friendly materials.

  • Wastewater-Grown Algal Biomass as Carbon-neutral, Renewable, and Low Water
           Footprint Feedstock for Clean Energy and Bioplastics

    • Free pre-print version: Loading...

      Abstract: Purpose of Review Growing algae in wastewater offers carbon-neutral biomass production and pollutant removal. However, practical applications of wastewater-grown algal biomass have social acceptability issues in the food and feed industries due to unexpected threats (such as human/animal pathogens and toxins) associated with the wastewater-grown biomass. Therefore, considering the substantial pollutant removal potential of microalgae and the abundance of wastewater as a growth media, alternative bioprocessing routes of the wastewater-grown biomass should be developed. This review highlights some non-food and non-feed applications of wastewater-grown algae biomass. Recent Findings Wastewater-grown algal biomass contains high amounts of carbohydrates, proteins, and lipids depending upon the composition of wastewater and algal species grown. These three significant metabolites are precursors to bioenergy and biomaterial products such as bioethanol, biogas, and bioplastics. Hydrolysis of the wastewater-grown algal biomass can be easily improved to enhance the microbial fermentation yields to produce bioethanol and biobutanol. Fresh algal biomass, residual biomass, or both can be used as feedstocks in anaerobic digestion/co-digestion to produce biogas. Depending upon the selected species, wastewater-grown algal biomass can also produce biopolymers whose productivity depends on growth conditions, wastewater composition, and biopolymer synthesis method. Enzymatic, eco-friendly chemicals and mechanical approaches used to prepare biopolymers from algal biomass should be optimized for higher yields of biopolymers. Summary Although wastewater-grown biomass has acceptability issues, it offers certain environmental benefits, including atmospheric carbon capture, phycoremediation of pollutants, and water recycling. This manuscript highlights the recent progress and emerging trends of wastewater-grown algal biomass as a feedstock with potential applications for fermentation, anaerobic digestion, and bioprocessing to produce clean energy and bioplastics.

           Measurements

    • Free pre-print version: Loading...

      Abstract: Purpose of Review Calculating atmospheric aerosol radiative forcing is a crucial aspect of climate change research. The aerosol scattering phase function stands out as a vital parameter for radiative forcing computations and holds significant importance in the remote sensing retrievals of aerosols. Despite its significance, research on aerosol scattering phase function measurements has been limited over the years. This review article provides a comprehensive summary of relevant studies on the measurements of aerosol scattering phase functions. Recent Findings In recent times, the application of imaging detection techniques in the measurement of aerosol scattering phase functions has emerged, highlighting advantages such as portability and high temporal-angular resolution. In addition, the development of aerosol retrieval algorithms facilitates a broader application of the results obtained from aerosol scattering phase function measurements in estimating aerosol physical properties and satellite retrievals. Summary This review introduces the measurement techniques, instruments, and retrieval algorithms associated with aerosol scattering phase functions, encompassing laboratory experiments, in situ field measurements, and remote sensing retrieval. The measurement results and related research on aerosol morphological effects and physical property retrievals have been summarized. Finally, it outlines future research prospects, suggesting improvements in instruments, experimental expansion, and enhanced data analysis and application, providing feasible suggestions for further studies.

  • Atmospheric Emissions from Electricity Generation in Southeast Asia:
           Development Trend and Policy Responses

    • Free pre-print version: Loading...

      Abstract: Purpose of Review Rapid economic development accompanied by urbanization, motorization, and industrialization, together with population growth, puts great pressure on the power sector in Southeast Asia (SEA) to meet energy demand. This paper reviews the past 20-year power generation in SEA countries to analyze potential impacts on atmospheric pollution using DPSIR framework. Recent Findings In 2020, total region electricity generation reached 1050 TWh, 3.1 times above that of 2000, and is projected to further increase by 2.5 times in 2050. During the period, the annual per capita generation increased 2.4 times. Indonesia, Malaysia, Thailand, and Vietnam were the main electricity producers, sharing 83% in 2020. Coal and natural gas based thermal power plants (TPPs) were dominant with 72% of the total electricity produced, whereas low-carbon renewable energy, although increased during the period, shared only 25% in 2020. In 2018, the sectoral atmospheric emissions of different species increased by 2.4–11.5 times above 2000, contributing 55.3%, 26.8%, and 26.7% to the region’s total anthropogenic emissions of SO2, CO2, and NOx, respectively. Summary Heavy reliance on fossil fuels makes the power sector a key emission source of air pollutants and greenhouse gases. SEA governments have promulgated policies and regulations for TPPs and set net zero emissions targets. These policies, directly and/or indirectly address atmospheric pollution, once fully implemented, bring in more secure and sustainable power sources in the region, along with multiple benefits to air quality, human health, environment, ecosystem, and the climate.

  • Sources, Variations, and Effects on Air Quality of Atmospheric Ammonia

    • Free pre-print version: Loading...

      Abstract: Purpose of Review As the most abundant alkaline trace gas in the atmosphere, NH3 plays a critical role in the formation of atmospheric particulate matter and nitrogen cycling in ecosystems. NH3 emissions have been increasing globally over the past few decades. To provide a clearer understanding of atmospheric NH3, this paper presents a systematic review of the literature on the sources and variability of atmospheric NH3 and describes the contribution of atmospheric NH3 to PM2.5. Recent Findings (1) The primary source of atmospheric NH3 emissions is agriculture; other sources include combustion-related emissions and volatilization from soil and oceans. However, recent studies have revealed the major role of nonagricultural sources in urban areas. (2) The spatiotemporal variability of atmospheric NH3 is complex, and its mechanisms are not entirely clear. (3) Atmospheric NH3 can participate in multiple atmospheric chemical processes and to the formation of fine particulate matter. Summary This review summarizes the latest knowledge on the sources and variability of atmospheric NH3 and highlights the necessity of controlling atmospheric NH3 emissions. However, significant knowledge gaps still exist in understanding the sources, trends, and effects of atmospheric NH3. Therefore, further research is essential to investigate the influencing factors and environmental effects of atmospheric NH3 concentrations, providing a scientific basis for the development of effective NH3 control strategies.

  • Critical Roles of Surface-Enhanced Heterogeneous Oxidation of SO2 in Haze
           Chemistry: Review of Extended Pathways for Complex Air Pollution

    • Free pre-print version: Loading...

      Abstract: Purpose of Review Complex air pollution has spread in the conurbation areas of China along with chemically complicated air pollution processes. Classic secondary-pollutant formation toward high concentrations of fine particulate matter (PM2.5) and ozone (O3) is imperfectly understood in the currently accepted chemical mechanisms. The combustion-produced fine particles contain abundant nanosized black carbon (BC) internally mixed with transition metal ions (TMI) and contribute to the complicated oxidation pathways and products substantially. Based on current understandings of multiphase sulfate formation, we propose that the surface-enhanced heterogeneous reaction processes can play critical roles in the fast formation of “haze chemistry smog” pollution. Recent Findings Pathways of sulfate enhancement by BC and TMI have been identified to explain the formation mechanisms of the missing sulfate sources. Responsible for additional production of secondary gas molecules and aerosols, the heterogeneous chemistry is initiated with surface photosensitive catalysis. In addition, unidentified atmospheric oxidizing capacity is recognized as part of the heterogeneous processes. Given unique surface-specific profiles and electronically excited dismutation reactions, BC and TMI particles can steadily generate reactive oxygen species (ROS) such as hydroxyl radicals (OH) and promote the oxidation of SO2. This phenomenon provides an extended insight into atmospheric free-radical chemistry. As such, the heterogeneous catalytic oxidation of SO2 on aerosol surfaces accounts for up to 69.2% of sulfate formation in haze episodes. Summary Unlike in-cloud aqueous oxidation, representative heterogeneous reaction pathways (i.e., TMI aqueous catalysis pathway and surface catalysis pathway) enhance sulfate formation via surface radical reactions in both winter and summer. The heterogeneous processes are thought to reduce gaps between model-predicted and measured sulfate levels. The physically and chemically active BC and TMI can change the composition, morphology, hygroscopicity, and optical properties of PM in their atmospheric aging processes. Therefore, the heterogeneous pathways facilitate rapid particle growth for haze pollution and help to understand and develop a new type of air pollution chemistry (i.e., “haze chemistry” processes) in China and other developing countries.

  • Meta-Analysis of Biochar as an Amendment for Arsenic Mitigation in Paddy
           Soils

    • Free pre-print version: Loading...

      Abstract: Purpose of Review The purpose of this review is to evaluate the effectiveness of biochar in immobilizing arsenic (As) in contaminated paddy soils and its impact on As availability and bioaccumulation in rice, as well as rice plant biomass. Recent Findings Recent studies have focused on managing As contamination in agricultural fields, with a particular focus on South and Southeast Asia, where rice, a primary food source and As accumulator, is of significant concern. Biochar, a product of biomass pyrolysis, has emerged as a viable solution for environmental remediation due to its effectiveness in immobilizing metal(loid)s in water and soil. The successful implementation of biochar as a soil amendment strategy has led to growing interest in its use as an effective means of reducing the bioaccumulation and availability of metal(loid)s, including As. Summary A meta-analysis of 25 studies revealed that biochar generated from maize and sewage sludge successfully reduced As availability and bioaccumulation in rice grains. In addition, the use of biochar led to higher biomass and yield of rice crops compared to control groups. Modified biochar was more effective in decreasing As availability, likely due to interactions with iron and calcium phases or complexes occurring in or on the biochars. Nevertheless, at elevated biochar dosages, As mobilization was noted in field conditions which warrants further investigation.

  • Noise from Unconventional Aircraft: A Review of Current Measurement
           Techniques, Psychoacoustics, Metrics and Regulation

    • Free pre-print version: Loading...

      Abstract: Purpose of Review This review aims to evaluate and discuss the current advances in the measurement and assessment of the noise generated by unconventional aircraft, such as unmanned aircraft systems (UAS) and urban air mobility (UAM) vehicles. Building upon the findings of this review, research gaps are identified, and further work is proposed to enhance existing and emerging methods for the appropriate noise management of these advanced air mobility (AAM) technologies. Recent Findings Noise has been highlighted as one of the key concerns for the wider deployment of UAS and UAM operations. This is suggested to be due to having acoustic signatures with sound characteristics commonly associated with noise annoyance, such as ‘sharpness’ (the perceived proportion of high-pitched sonic energy) and ‘tonality’ (the perceptual prominence of concentrated sonic energy at discrete frequencies). These types of ‘psychoacoustic features’ are thought to be connected with observations of increased noise annoyance for AAM, compared with conventional aircraft and road vehicles, at the same level of sound exposure. Summary In the last few years, there has been a growing body of research on UAS and UAM noise. Research has focused on a comprehensive understanding of the sound sources of these unconventional aircraft under a wide range of operating and operational conditions. Based on gathered evidence, measurement protocols for both laboratory and field studies are very advanced for the acoustic characterisation of UAS in terms of sound level, frequency and directivity. Looking at the human response to UAS and UAM noise, loudness has been consistently reported as the main contributor to noise annoyance, with second-order contributions from other psychoacoustic features, such as sharpness, tonality and ‘amplitude modulation’ (fluctuations in loudness over time), varying among studies. Noise targets for UAS certification have been derived from existing regulations for conventional aircraft and rotorcraft, but might not account for the usually reported annoyance offset between UAS/UAM and conventional vehicles. Key research gaps identified include the lack of studies focusing on multiple events, and deeper understanding of the influence that personal or contextual factors may have on responses, which will be important for the development of robust methods for the assessment and minimisation of community noise annoyance due to the operation of these unconventional aircraft.

  • Crosslinked Cyclodextrin as Potent Composite For Removal of Wastewater
           Pollutants

    • Free pre-print version: Loading...

      Abstract: Purpose of Review Pollution from wastewater is a perpetual environmental issue worldwide that negatively impacts the ecosystem and human beings. The use of natural-based compounds such as cyclodextrin (CD) to remove pollutants from water and wastewater systems has been reported by various researchers. Nevertheless, its direct use in wastewater treatment is hampered by its water-soluble properties. Beta-cyclodextrin (β-CD) is a cyclic oligosaccharide compound that can effectively trap pollutants from wastewater by the formation of truncated inclusion complex with various molecules. Hence, it is the motivation of this article to review the effectiveness and the recent strategies of crosslinked-β-CD toward remediation of various pollutants from wastewater. Recent Findings The crosslinked-β-CD was found as an improvement for native β-CD in the purpose of wastewater pollutant remediation. Strategies in chemical crosslinking include the choice of suitable crosslinkers, the type of support materials, and surface modifications. It was observed that different strategies resulted in various degrees of performance of the composite β-CD adsorbents. The efficiency of adsorption process was influenced by the operational parameters such as pH, contact time, and initial pollutant concentration, whereby it was characterized by the recyclability, adsorption capacity, and mechanical strength. The emergence of nanotechnology has led to a great improvement to the existing composite-β-CD adsorbent by providing a large surface area, where it can be easily functionalized and modified toward the targeted molecules. Summary Crosslinking is a versatile method for developing a composite-β-CD adsorbent for pollutant uptake as it employs a simple technique and performs a simple separation process with moderate operational conditions. Graphical The 3D structure of β-cyclodextrin resembles a truncated cone, having characteristics of hydrophilic surface and hydrophobic cavity and capable to trap molecules inside its cavity. The graphical abstract shows the flows of this review paper. The crosslinking strategies, the operational parameters, and the adsorption performance of the composite CD-adsorbents were reviewed and discussed

  • Arsenic and Human Health: New Molecular Mechanisms For Arsenic-Induced
           Cancers

    • Free pre-print version: Loading...

      Abstract: Purpose of Review Chronic inorganic arsenic (iAs) exposure affects over 220 million people throughout the world. Given that iAs is ubiquitous in the environment, it is important to understand the human health consequences of chronic iAs exposure. The purpose of this review is to highlight and evaluate research findings within the past 5 years that address the molecular mechanisms responsible for cancers caused by chronic iAs exposure. We also propose new research directions for the iAs research field based on the newest uncovered mechanisms for how this age-old poison promotes cancer. Recent Findings Within the past 5 years, studies provide evidence that chronic iAs exposure promotes kidney, prostate, liver, and breast cancer in humans. New molecular mechanisms that promote cancer development by iAs exposure in skin, lung, bladder, kidney, prostate, liver, and breast include histone modifications, DNA and RNA methylation, non-coding RNA expression, disruption of alternative splicing, and inhibition of the DNA damage response. Summary Recent studies highlight disruption of epigenetic and epitranscriptomic modifications and/or the DNA damage response by chronic iAs exposure across many models of iAs-induced carcinogenesis, including cancers that are not classically defined as being caused by chronic iAs exposure. Understanding the molecular mechanisms underlying initiation and metastasis of iAs-induced cancers is essential for improving detection and targeted treatment of iAs-induced cancers. Graphical

  • Sealants and Other Management Strategies for PFAS-Contaminated Concrete
           and Asphalt

    • Free pre-print version: Loading...

      Abstract: Purpose of Review The unique properties of per- and polyfluoroalkyl substances (PFASs) have seen their widespread adoption, subsequent accumulation in the environment and concern regarding potential environmental effects. Globally, airfields and paved firefighting training surfaces are hotspots for accumulation of PFAS due to extensive use of aqueous film-forming foams (AFFF). Evidence from contaminated concrete and asphalt airfield and training pavements suggests they may serve as an enduring PFAS source. This review investigates sealants as remediation technologies to minimise PFAS mobilisation from pavements drawing on current knowledge of remediation options for soils, sediments, surface and groundwaters. Recent Findings The review did not identify any published sealant information specific to PFAS. Our analysis showed that surface and penetrative sealants may offer an immediate solution via encapsulation of PFAS residues in concrete and asphalt. The most promising surface sealants likely to minimise water ingress and PFAS leaching are selected polymers and (modified) bitumen, owing to the relatively low cost, good adhesion, trafficability and chemical, heat and UV resistance. Potential also exists to enhance PFAS immobilisation using additives to absorb or otherwise chemically bind PFAS. Prospective penetrative sealants include silicates or siloxanes that bind to internal mineral surfaces and/or fill pores to restrict PFAS mobility. It is likely that combinations of surface and penetrative sealants will be required to meet functional, operational and management requirements with respect to new or existing contamination in concrete or asphalt pavements. Summary At present, few if any sealants have been evaluated for their ability to bind or mitigate PFAS mobility. This review serves as a starting point for further studies to evaluate their short or long-term effectiveness in immobilisation of PFAS residues in in situ or ex situ concrete and asphalt. Several knowledge gaps along with suggestions for future research have been made.

  • Arsenic in the Soil-Plant-Human Continuum in Regions of Asia: Exposure and
           Risk Assessment

    • Free pre-print version: Loading...

      Abstract: Abstract In this review article, a comprehensive meta-analysis based on available literature information has been undertaken to make a relative comparison of total arsenic in rice grain. This involves analyzing the findings of various peer-reviewed studies that examined arsenic-contaminated Asian regions. Also, this article highlights the regional-level human health risks caused by the consumption of arsenic-contaminated rice in the three regions of Asia. Deriving such information at the continental level is of major importance in view of the need for proper monitoring and alleviating serious and continually emerging human health issues in arsenic-contaminated areas. One aim of this paper is to highlight the potential of a viable modeling approach for appraising the danger posed by arsenic in soil-plant-human system. There is an urgent need to fix the safe limit of bioavailable arsenic in soil because total arsenic in soil is not a good index of the arsenic hazard. Our hypothesis is finding out whether the modeling approach can be used in establishing a safe limit of bioavailable arsenic in soils with reference to human health. To achieve the above-mentioned objectives, we have selected reported rice grain arsenic content data from Asian countries following the PRISMA guidelines. Carcinogenic and non-carcinogenic risk was calculated following the US EPA’s guidelines. It emerged that adults in Asian countries are prone to a high risk of cancer due to their consumption of arsenic-contaminated rice. South Asia (SA), South East Asia (SEA), and East Asia (EA) exceeded the US EPA-prescribed safe limit for cancer risk with ~ 100 times higher probability of cancer due to rice consumption. The hazard quotient for the ingestion of arsenic containing rice was 4.526 ± 5.118 for SA, 2.599 ± 0.801 for SEA, and 2.954 ± 2.088 for EA. These figures are all above the permissible limit of HQ of 1. The solubility free ion activity model can predict arsenic transfer from soil to rice grain based on easily measurable soil properties and be used to fix the safe limit of bioavailable arsenic in paddy soils. The methods and findings of this review are expected to be useful for regional-level policymaking and mobilizing resources to alleviate public health issues caused by arsenic.

  • Heavy Metals in Indoor Dust in China: Occurrence, Source, and Health Risk

    • Free pre-print version: Loading...

      Abstract: Exposure to heavy metals in indoor dust may affect human health and has gained increasing attention in recent years. However, the occurrence, sources, and health risks of heavy metals in indoor dust in China are still poorly understood, thus leading to certain knowledge gaps. This review systematically discussed the pollution characteristics and the associated health risks of heavy metals in indoor dust in China. Results show that the heavy metals in indoor dust in China are more serious than that in other countries with concentration distribution patterns of Zn > Mn > Pb > Cu > As > Cr > Ni > V > Co ≈ Cd > Hg. Mining and smelting activities, electronic waste recovery, and industrial production can increase heavy metal concentrations in indoor dust in sampling cities. Due to the variation of sources, significant spatial differences are observed among different regions and between rural and urban homes. Results from source apportionment show that mining activity and traffic are the dominant sources of indoor heavy metals. In comparison with adults, children have higher non-carcinogenic and carcinogenic risks due to more frequent ingestion of indoor heavy metals. Residents in South China are suffering from high carcinogenic risks due to high As occurrence levels. Children in South, East, and Southwest China are suffering from non-carcinogenic risks due to Pb exposure. To our theme, more studies, especially in rural homes, involved with more kinds of microenvironments are welcomed in the future. Meanwhile, in the premise of setting a standard guideline for a consistent target heavy metal, activity patterns should be considered when estimating the health risk. Results from this study are expected to provide crucial information for policymakers and researchers to alleviate indoor heavy metal pollution. Graphical

           Prevention: Opportunities, Challenges, and Future Outlook

    • Free pre-print version: Loading...

      Abstract: Purpose of Review The ability to monitor soil moisture wirelessly can deliver immense benefits to annual crops. Real-time soil moisture monitoring allows for accurate and on-demand irrigation to achieve optimal growth and avoid overwatering. It is also an effective pollution prevention method, eliminating excessive run-off to prevent soil erosion, sediment discharge, and the dispersion of key water pollutants such as nitrogen and phosphorus to natural waterway. Current soil moisture sensors require constant a power supply or battery. Wiring can be used for soil moisture sensing of perennial crops but is also not suitable for annual crops that require significant tillage. This review aims to delineate the readiness of moisture sensors and wireless power transfer technology for developing a wireless soil moisture sensing network. Recent Findings Of the many types of soil moisture sensors, only a few are compatible to a wireless network. They either are too expensive, have unreliable measurement accuracy, or require too much power. This review shows that capacitive sensor is a potential candidate for underground sensor networks in terms of affordability, measurement reliability, and power consumption. In addition, among all currently available wireless power transfer technologies, inductive power transfer has the potential to supply adequate power for wirelessly charging underground sensors and meet other requirements of an underground sensing network. Summary This review evaluates available soil moisture sensing and wireless power transfer techniques for wireless underground moisture sensing. The combination of capacitive sensing and inductive power transfer technologies has been identified as a potential solution for wireless underground sensor networks. Future research should focus on improving the calibration and post-processing algorithm for capacitive sensor while the misalignment and impact of soil need to be considered to enhance the performance of the inductive power transfer system.

      Abstract: Purpose of Review The article reviews the literature on soundscape studies to analyse (i) which of the methods included in the Technical Specification (TS) 12913-2:2018 by the International Organization for Standardization (ISO) for collecting soundscape data from individuals are predominantly used in scientific research and (ii) what is the level of compliance with ISO recommendations of the methods employed in scientific research. Recent Findings The ISO/TS 12913-2:2018 provide three possible protocols for individuals’ soundscape data collection (Methods A, B, and C). Despite standardization efforts, a reference method has yet to be identified to improve comparability amongst studies and the formation of scientific evidence. Summary The analysis of 50 peer-reviewed papers published from 2018 (year of release of ISO/TS 12913-2) showed that Method A is the prevalent one, adopted by 94.4% of the identified studies. Full compliance with ISO technical specification recommendations is in any case quite limited, and almost no study is strictly adhering to them. Attributes are not always suitable to cover all the acoustic contexts (e.g. indoor environments). This is an indicator that the field is still developing, but it also signals that technical specification recommendations leave room for ambiguity or are not always implementable. This study is ultimately intended to offer recommendations on future development of the protocols in the standardization process. Graphical

  • Influence of Green Areas on the Urban Sound Environment

    • Free pre-print version: Loading...

      Abstract: Purpose of Review Urban green spaces provide benefits for human health and well-being, among other properties, thanks to their ability to attenuate environmental pollutants. The sound environment is not healthy in most cities, and this situation has not changed in recent decades. These green spaces are potential quiet areas with good acoustic quality if they are designed and planned properly from a multidisciplinary perspective. Although the mitigating effects of green infrastructure have been extensively studied, their application in green areas has been very limited. The objective of this study is to analyze those characteristics of green spaces that contribute to a healthy soundscape and, in turn, the benefits that this would give them to the characteristics of green areas, users, and their physical environment. Recent Findings Current studies show that to accurately determine the relationship between green spaces and health and well-being benefits, it is necessary to know the interaction with other environmental variables, including the soundscape. The development and application of ISO/TS 12913-2 have promoted the consideration of the soundscape and the use of appropriate procedures for its evaluation. Summary The inclusion of soundscape quality in epidemiological studies will improve the quantification of the effects of green spaces on the health and well-being of citizens. Only the consideration of global indicators, such as Lden (dB), show the importance of the sound environment in the interaction with other environmental variables and user activities for the determination of the effects of green spaces on health.

  • Climate Change Effects on Phosphorus Loss from Agricultural Land to Water:
           A Review

    • Free pre-print version: Loading...

      Abstract: Purpose of Review Phosphorus (P) loss from agricultural land to surface water is a leading cause of water quality deterioration. We reviewed the climate change impacts on sources and transport of P and how they can exacerbate P loss from agricultural soils to waterways. Recent Findings The effects of climate change include extreme precipitation events, increased temperature, elevated atmospheric carbon dioxide (eCO2), and saltwater intrusion induced by sea level rise. Extreme precipitation (EP) events cause accelerated transport of dissolved and particulate P from soils, exacerbated after the application of fertilizers and manures or drought. The unpredictability of EP leads to greater incidental P losses as appropriately timing nutrient applications is more challenging. Increased soil and air temperatures influence soil microbial communities and P-solubilizing microbes, but their effects on P losses are uncertain. Likewise, eCO2 may increase plant growth, P demand, and soil P cycling, but its impact on P losses is unclear. Saltwater intrusion caused by sea level rise can further mobilize P in high (legacy) P soils and enhance P loss from land to water. Summary Climate change is likely to increase P losses due primarily to increases in extreme precipitation and saltwater intrusion in coastal areas. These impacts will be geographically variable. Current P loss models could be improved by including climate change effects on P sources and transport, the inclusion of legacy P soil data, and accounting for P losses from legacy P soils.

  • Sustainable Conversion of Biowaste to Energy to Tackle the Emerging
           Pollutants: A Review

    • Free pre-print version: Loading...

      Abstract: Biowaste is a major source of organic material that can be converted into energy through various processes such as anaerobic digestion, composting, and pyrolysis. However, emerging pollutants, such as pharmaceuticals, pesticides, herbicides, and personal and household products, are a growing concern in wastewater treatment that can be effectively removed by biowaste-to-energy processes. While these contaminants pose significant challenges, the development and implementation of effective monitoring programs and risk assessment tools help to mitigate their impact on human health and the environment. Likewise, monitoring programs, challenges, legislations, and risk assessment tools are essential for understanding and managing the risks associated with emerging pollutants. Biowaste recycling is an important aspect of a biocircular economy perspective as it involves the conversion of organic waste into valuable resources that can be reused sustainably. The review discusses the modern approaches that offer several advantages, including reducing the waste disposal and generating renewable energy while addressing emerging wastewater treatment pollutants. To achieve the goal of a circular economy, modern biotechnological approaches including anaerobic digestion, composting, bioleaching, bioremediation, and microbial fuel cells offer a sustainable and effective way to convert waste into valuable products. These bioproducts alongside energy generation using waste-to-energy technologies can provide economic benefits through revenue generation, reduced waste disposal costs, and improved resource efficiency. To achieve a biocircular economy for biowaste valorization, several stakeholders, including waste collectors, waste management companies, policymakers, and consumers need to be involved. The sustainable conversion of biowaste to energy is an essential and instrumental technology in environmental sustainability. Graphical

  • Microbiome Wetlands in Nutrient and Contaminant Removal

    • Free pre-print version: Loading...

      Abstract: Purpose of Review Constructed wetlands (CWs) are engineered systems that have been proven as an alternative option to traditional wastewater treatment technologies because of their ability to provide cost-effective and energy-efficient solutions. This technology depends on natural microbial/biological, physical, and chemical processes to treat wastewater. Processes removing impurities in constructed wetlands are based on the combination of interactive systems such as selected plant species, the nature of substrate used for constructed wetlands, biofilm growth, microbial diversity, and several biogeochemically affected reaction cycles in wetland systems. Microorganisms play a vital role in these processes such as the degradation of pollutants and the transformation of nutrients. Microorganisms remove the pollutants from CWs by catalyzing chemical reactions, biodegrading, biosorbing, and supporting plant growth. An in-depth analysis of the function of microorganisms in CWs is important to understand. This review deals with the recent developments in constructed wetland systems from a microbiological perspective to treat impurities present in wastewater. It focuses on the studies of microbial diversity in CWs and the role of enzymes produced by microbes, the influence of the substrates of CWs on microbial diversity, the influence of the hydraulic design of CWs on the growth of microorganisms, the role of specific microbes in the removal of pollutants and the different software, analytical equipment, tools, and techniques used to measure/quantify the parameters of interest or to design and operate a wetland. Recent Findings The combination of different types of substrates in constructed wetlands can form different types of zones such as anaerobic and aerobic zones which can allow to form a diversity of microorganisms. In addition, plant diversity plays a vital role in microbial growth by providing O2 and increasing plant biomass production which influences the soil microbial community. Moreover, the influent carbon source influences the biomass as for example when the COD/N ratio is increased by 80%, the phospholipid fatty acids (PLFA) concentration of microbial biofilm in glucose constructed wetlands is increased by 50%. At the same time, the biomass of aerobic and anaerobic bacteria and fungi increased significantly. In addition, different microorganisms are responsible in removing different types of heavy metals and micropollutants. Summary This article provides useful information on the understanding of the diversity of microbes, influencing factors on the growth of microorganisms, and the efficiency of pollutant removal process in CWs. Overall, this review provides new ideas and directions for the improvement of constructed wetlands from a microbiological perspective.
