  • An Update on Agricultural Wastes Used as Natural Adsorbents or Coagulants
           in Single or Combined Systems for the Removal of Dyes from Wastewater

    • Abstract: Abstract Over a billion people in developing countries do not have access to clean water. Industries such as textiles, tanneries, and plastics release wastewater with toxic dyes that require treatment to remove the color. Adsorption and coagulation are known methods for removing dyes from wastewater. The production of natural adsorbents and coagulants involves the use of waste from agricultural products, which makes them cost-effective and environmentally friendly. They can be modified to achieve high dye removal rate. Natural adsorbents and coagulants are more eco-friendly than synthetic materials such as activated carbon and alum, because they can achieve similar levels of removal efficiency while being biodegradable and reusable. The combination of two methods can help to reduce the required dosage of adsorbent and coagulant and simultaneously improve the rate of dye removal. The purpose of this review is to evaluate and contrast the efficacy of recent natural agricultural adsorbents and coagulants, as they are environmentally friendly and abundant in nature. Additionally, it aims to introduce novelty by reviewing the combined coagulation/flocculation and adsorption systems in the treatment process for removing dyes, utilizing adsorbents and coagulants derived from agricultural wastes. As it turns out, the most examined dyes for removal were Methylene Blue and Congo Red and as adsorbents were used banana peels, orange peels, and nut. Furthermore, Moringa oleifera is used as a coagulant in both single and combined systems. Regarding adsorption, it was observed that banana peels could remove different dyes with high efficiency.

  • Synthesis of Nano-silica Oxide for Heavy Metal Decontamination from
           Aqueous Solutions

    • Abstract: In the current study, nano-silica oxide (nano-SiO2) was fabricated via the sol-gel technique. Then, the prepared nano-SiO2 was characterized using X-ray diffractometer (XRD), transmission electron microscopy (TEM) coupled with energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and Brunauer-Emmett-Teller (BET) specific surface area analysis. Furthermore, the fabricated nano-SiO2 was applied for the adsorption of lead Pb (II) and chromium Cr (VI) from aqueous solutions. Additionally, the influence of different operating factors such as contact time (0–180 min), initial pH (1–11), nano-SiO2 dose (0.1–8 g L−1), initial metal ion concentration (5–100 mg L−1), and the temperature (30–85 °C) was investigated. The nano-SiO2 doses of 0.5 and 1 g L−1 were selected as the optimal adsorbent dose for the removal of Pb (II) and Cr (VI), respectively. These doses achieved a removal efficiency of 82.3% and 78.5% for Pb (II) and Cr (VI), after 60 and 90 min, at initial pH values of 5 and 2, respectively, using 10 mg L−1 initial metal concentration, and at room temperature. Lastly, kinetic and equilibrium studies were competently fitted using the pseudo-second-order and Freundlich models, respectively. Adsorption thermodynamic studies designate the spontaneous and thermodynamic nature of the adsorption process. These results reveal the efficiency of the fabricated nano-SiO2 as an adsorbent for heavy metal removal from aqueous solutions. Graphical

  • Effective RhB Dye Removal Using Sustainable Natural Bioadsorbents
           Synthesized from Avocado Seed and Skin

    • Abstract: Abstract Managing waste generated by the food industry is a pressing environmental challenge, and traditional disposal methods such as landfilling or incineration are no longer viable solutions. However, by recovering and valorizing waste in wastewater treatment, we can address the waste management issue and the energy-intensive nature of conventional treatment methods with processes compatible with renewable energy technologies. In this work, avocado skin and seed are valorized for their application in removing Rhodamine B (RhB) dye. Avocado skin (ASk) and seed (ASe) were recovered and recycled separately to develop natural bioadsorbents. Biomaterials were characterized by XRD, XPS, ICP-MS, ATR-FTIR spectroscopy, TGA, N2 adsorption/desorption, and SEM. The ASk and ASe bioadsorbents were employed to remove RhB at four experimental conditions: pH, RhB concentration, bioadsorbent concentration, and temperature. RhB removal was followed by UV–Vis spectroscopy. The results show that at pH 3, the highest percentages of dye removal are achieved, using ASk and ASe, with 88 and 92% removal, respectively. ASe bioadsorbent is more effective for removing RhB dye, reaching 92% after 4 h of contact with 2 g L−1 of bioadsorbent and at 30 °C. Experimental results better fit a pseudo-second-order kinetic model and the Langmuir adsorption model, with maximum adsorption capacities of 13.1240 and 17.9998 mg g−1 for ASk and ASe, respectively. The results show that natural bioadsorbents are suitable options for environmental remediation.

  • Sulfur Signature of a Mediterranean Wetland: The Case of Soils of the
           Inundated Floodplain Area at the Tablas de Daimiel National Park

    • Abstract: Abstract In the Mediterranean region, numerous wetlands co-exist with competitive agricultural systems. Although wetlands’ hydrology (in water volume, source, and residence time terms) plays a major factor in their ecosystem structure, many of these wetlands have been subjected to different degradation processes. One such case is the Tablas de Daimiel National Park (TDNP), which witnesses one of its most environmentally sensitive times. In this context, scarce information is available on the sulfur (S) contents in this wetland. To diagnose this wetland’s degradation status, 43 soil samples were selected and analyzed to investigate S contents in the surface soils (0 to 30 cm) of the inundated floodplain area of the TDNP. They represent different degrees of exposure to pollutants and exposure to flooding. Sulfur determination was carried out by X-ray fluorescence. The S contents in the area range between 1.85 and 37.15 g kg−1, with a mean value of 13.71 g kg−1, which implies marked variability throughout this wetland. The highest values were observed near the wetland entrance via the Gigüela River, while the lowest ones appeared at its exit, with a relatively uniform gradient from the entrance to the exit. The relatively high S concentrations observed at sites other than the wetland entrance can be probably related to the continuous non-point source contamination with P, N, and S fertilizer applications, via runoff agricultural production systems. The results of this study are essential for understanding and predicting total S variability within the TDNP (Spain), which can interfere with soil management practices.

  • Water Quality and Dissolved Organic Carbon Content in Agricultural
           Streams: Northern Nile Delta Region, Egypt

    • Abstract: Abstract Sustainable development goals (SDGs) 2 (zero hunger), 6 (clean water and sanitation), and 15 (life on land) are related to the human-water-soil nexus. Soil organic carbon and nutrients can be removed and transported to waterways through runoff and drainage. The main goals of this study are to quantify the water quality for irrigation and assess the dissolved organic carbon (DOC) contents in streams in the northern Nile Delta, Egypt. A 4-year water quality monitoring program is accomplished by collecting 35 irrigation and drainage water samples per year from the study area. The measured water quality parameters are as follows: salinity, pH, Na, SAR, Cl, and NO3–N. In addition, the DOC content is accessed. The salinity hazard ranged from moderate, for most irrigation samples, to high and very high for drainage samples. All collected water samples have low to medium sodium hazards. Results indicate that average DOC contents in irrigation canals are 2.32 and 2.93 mg L−1 for the summer and winter, respectively. The respective means of DOC concentration in drainage canals for the summer and winter seasons are around 3.96 and 5.09 mg L−1. This study revealed significant differences in EC, pH, Na, Cl, and SAR, as water quality parameters, between irrigation and drainage canals. Additionally, the studied agroecosystem has seasonal variability in DOC concentration in irrigation and drainage canals between summer and winter. Overall, reusing drainage water for irrigation in the study area requires the selection of suitable crops and site-specific management.

  • Irrigation Water Management in a Water-Scarce Environment in the Context
           of Climate Change

    • Abstract: Climate change has a considerable impact on irrigated agriculture, which is vital for food and fiber production. In this study, in the context of climate change, simulation model CROPWAT 8 was employed to compute the reference evapotranspiration, and net irrigation water requirement for wheat, barley, maize, sugar beet, potato, tomato, and date palm. In addition, the WaterGEMS model was utilized to design a new sprinkler irrigation system to run long-term simulations of hydraulic behavior within pressurized pipe networks to irrigate 43 acres for two arid sites (Siwa Oasis and West Elminya fields) inside the 1.5-million-acre groundwater irrigation project in the Egyptian western desert. Five scenarios for climate change were employed in the current (1991–2023), representative concentration path (RCP) 8.5 greenhouse gas emission scenarios for the 2040s, 2060s, 2080s, and 2100s. Mean ETo values for the current scenario show 4.56 and 5.7 mm for the Siwa Oasis and West Elminya fields, respectively. The climate changes cause an increase of the reference evapotranspiration by 4.6, 5.9, 9.4, and 12.7% for RCP: 8.5 greenhouse gas emissions for the 2040s, 2060s, 2080s, and 2100s scenarios, respectively, for the Siwa Oasis field. On the other hand, an increased ratio for the reference evapotranspiration by 4.2, 5.4, 8.6, and 11.6% was observed for the scenarios in the West Elminya field, respectively. The designed sprinkler system indicated a capacity of 111.4 m3 h−1 and 167 m3 h−1 for Siwa and West Elminya fields, respectively. The study suggests using crop patterns for wheat, barley, potato, and sugar beet to save irrigation water. Graphical abstract

  • Assessing the Presence of Petroleum Hydrocarbons in the Punta Carnero
           Estuary (Ecuador)

    • Abstract: Chronic hydrocarbon spills are a threat to coastal ecosystems, and their impact on the water quality along watercourses should be characterised to medium long term in order to assess the risk and define cost-effective and sustainable remediation strategies. For this purpose, a methodology for the measurement of total petroleum hydrocarbons (TPH) on a spatio-temporal scale was designed, implemented and validated in the Punta Carnero estuary, in the Santa Elena province, western Ecuador, which is affected by hydrocarbon pollution. The selection of monitoring stations was made according to the different inflows along the water system corresponding to the different anthropogenic activities in the area, in order to assess whether the effluents involve critical levels of pollution. Measurements of hydrodynamic, environmental and vegetation cover parameters were also carried out to assess their possible variations as a consequence of the impact of the spatio-temporal TPH concentrations. An increase in hydrocarbon concentrations was observed from 2013 to 2021. Mean annual TPH levels were above the maximum allowable limit for the protection of aquatic and other wildlife in estuarine waters according to the Ecuadorian regulation for environmental quality. An increase in mangrove tree cover could contribute to an exponential decrease in contamination levels. The methodology used in this study may support the quantifying of TPH content in future applications, which is a priority task for the restoration of degraded ecosystems. Graphical abstract

  • Environmental Perception of Solid Waste Management in the Hurtado
           Balneary, Colombia

    • Abstract: Abstract Environmental perception serves as a powerful tool for identifying community needs and potential within their surroundings. This study assessed tourists’ environmental perception regarding solid waste and its impact on the Hurtado Balneary, located in Valledupar, Colombia. The investigation delved into the environmental attitudes and behaviors of 769 balneary users by employing a combination of observation, photographic documentation, and a comprehensive 21-question online survey. The findings are 98.8% of participants acknowledged the adverse effects of solid waste on the environment, with 98% demonstrating a willingness to participate in waste management efforts. Furthermore, 42.13% exhibited limited awareness regarding waste management practices, reflecting a concerning lack of public interest and commitment (41.61%). Statistically significant disparities (p > 0.05) emerged 59% of waste items were not appropriately disposed of in designated receptacles. Reasons for this included a lack of a sense of belonging (50.2%) and inadequate environmental education (45.6%). Ninety-six percent expressed the need for river conservation signage, while 59.8% did not undertake any form of environmental training. The study’s implications extend beyond the Hurtado Balneary, potentially informing solid waste management strategies in other aquatic environments. This investigation aligns with three Sustainable Development Goals: SDG 12, emphasizing responsible consumption and production; SDG 13, addressing climate action; and SDG 15, advocating for life on land and below water.

  • Camp Lejeune Marine Cancer Risk Assessment for Exposure to Contaminated
           Drinking Water From 1955 to 1987

    • Abstract: Abstract This study utilizes guidance from the United States Environmental Protection Agency (USEPA) and the Agency for Toxic Substances and Disease Registry (ATSDR) to calculate the cancer risk to United States Marines who were exposed to carcinogens in drinking water at Marine Corps Base Camp Lejeune. Camp Lejeune is a 233-square-mile Marine Corps training facility in North Carolina. From 1953 to 1987, nearby dry cleaners, landfills, and underground storage tanks contaminated drinking water systems that served Camp Lejeune (ATSDR, 2017). Some of the most toxic contaminants found in the drinking water modeled by ATSDR include benzene, tetrachloroethylene (PCE), trichloroethylene (TCE), trans-1,2-dichloroethylene (DCE), and vinyl chloride (VC). ATSDR utilized MODFLOW and EPANET modeling software to determine the level of contamination in the three main drinking water systems at Camp Lejeune: Tarawa Terrace, Holcomb Boulevard, and Hadnot Point. This paper presents an application of methodology to quantify cancer risk for the Marines who lived and served at Camp Lejeune from 1953 to 1987 using ATSDR’s health assessment, chemical contaminant modeling, and USEPA methodology. While VC and TCE were found to be the main risk drivers, benzene and PCE also contributed to the cumulative cancer risk. This analysis shows (1) That the cancer risk was greatest during the 1970s and 1980s and (2) that the inhalation exposure pathway had the greatest contribution to overall cancer risk followed by ingestion, with the smallest contribution from dermal absorption.

  • Determination of Bioavailability, Potential Ecological and Human Health
           Risks, and Biomonitoring of Potential Toxic Elements in Gold Mine Tailings
           from Four Areas of Antioquia, Colombia

    • Abstract: Abstract Gold mining has helped many countries and regions grow and prosper. Yet, because of the significant environmental effects produced, waste management (mine tailings) has emerged as a crucial issue for the sector. In this study, the concentrations of several potential toxic elements (PTEs) (Fe, Zn, Cu, As, Hg, Pb, Cr, Cd, and Ni) in mine tailings from four gold mining operations (Yalí, Puerto Berrio, Buriticá 1, and Buriticá 2,) were quantified. A biomonitoring system has also been suggested, along with two environmental risk indexes for ecosystems and human health. To do this, composite samples of tailings were collected from the four regions. A PTEs analysis using an ICP-OES as well as physicochemical characterization (pH, electrical conductivity, cation exchange capacity, organic matter) have been performed. Indicators such as antioxidant activity and H2O2 content in Phaseolus vulgaris plants have been used to estimate the bioavailability of PTEs. In contrast to the pseudo-total concentration, the data showed that the bioavailable concentration of PTEs correlated with the risk. The ecological system and public health are more at risk from the mine tailings in Buriticá and Puerto Berrio. It has been demonstrated that P. vulgaris is a quick and effective technique to assess the danger to the environment and public health connected with mining regions, according to the suggested biomonitoring system. The findings of this study can assist the relevant authorities in taking quick action to improve environmental protection and risk management of hazardous waste in gold mining areas.

  • An Evaluation of Radon Concentrations in Arin Lake, Bitlis

    • Abstract: Abstract Arin Lake, situated in the Bitlis province, is a soda lake that holds significant ecological importance as a habitat for migratory bird species such as flamingos and white-headed ducks. In order to investigate the potential radiation exposure to the environment and living organisms in the area, radon concentration levels and dose calculations were determined for water samples collected from 27 different points in Arin Lake. The radon levels were determined using the AlphaGUARD PQ2000 PRO radon monitoring system, which has the range of 2–2.106 Bqm−3. The results of the radon concentration measurements are between 0.06 and 0.39 Bq/L, with a mean of value of 0.17 Bq/L. The annual effective doses for ingestion (Deff-ing) and inhalation (Deff-inh) were calculated at values ranging from 0.14 to 0.99 µSv/year. The radon levels were found to be lower than international standard values. Furthermore, the outcomes of this research were subjected to comparison with other studies in the literature.

  • Pike Mercury Concentration in Small Boreal Headwater Lakes During Four
           Decades of Regional and Local Changes

    • Abstract: Abstract We measured the total mercury (THg) concentration in the muscle of northern pike (Esox lucius L.) from 12 boreal headwater lakes once per decade during the 1980s to 2010s. Relations of pike THg to regional environmental changes, such as reduction of acid deposition and increase in water colour (i.e. browning), were examined as well as the effects of local lake-specific changes caused by introduced beavers (Castor canadensis) and intensive fishing of pike. No consistent decrease in pike THg took place during 1983–2013 despite the reductions in mercury emissions from European sources since the 1990s and the associated decreased mercury deposition in Finland. In most of the lakes, individual pike exceeded the recommended limit for human consumption (1 mg kg−1, wet weight). The highest THg levels were recorded in 2002 following intensive browning of the lakes in the 1990s in connection with decreased sulphate deposition. The effects of acid deposition were only seen as the highest pike THg in the two most acidic lakes in the early 1980s. After taking length effects into account, pike THg had a negative relationship with growth (i.e. growth dilution), but a positive relationship with water colour, iron, nutrients and maximum lake depth. Females grew faster and had lower THg than males. Pike THg was elevated in beaver-impacted lakes. Experimental removal of pike from three study lakes during 2005–2013 resulted in a decrease of pike THg. These findings emphasize the significance of local abiotic and biotic drivers when interpreting the regional long-term trends in pike THg.

  • Effects of Nano-zero-valent Iron and Earthworms on Soil Physicochemical
           Properties and Microecology in Cadmium-Contaminated Soils

    • Abstract: Abstract The capacity of nano-zero-valent iron (nZVI) and soil animals to remediate heavy metal–contaminated soil has been widely studied. However, the synergistic effect of soil animals and nZVI has not been thoroughly investigated. Here, we studied the combined effect of earthworms and nZVI on soil physicochemical properties and microecology during remediation of cadmium (Cd)–contaminated soil. The results showed that although amendment with nZVI reduced earthworm survival and biomass, the combination of nZVI and earthworms was effective at reducing the available Cd (ACd) content of soil and improving its quality. ACd most effectively reduced by 75.3% in the presence of earthworms under the 0.25% nZVI combination. Meanwhile, the combined action of earthworms and nZVI significantly improved soil properties and increased the diversity of soil microorganisms. In the earthworm-free system, nZVI reduced ACd by increasing soil pH and the abundance of Stenotrophobacter in Cd-contaminated soil, in addition to the co-precipitation and adsorption reported in previous studies. Correlation analysis revealed that the combination of nZVI and earthworms synergistically decreased ACd by decreasing soil OM and increasing the relative abundance of Opitutus and Gemmatta. Overall, our study indicates that the combination of nano-zero-valent iron and earthworms is a potential system for in situ remediation of Cd-contaminated soils and provides a deep understanding of the mechanisms involved in remediation.

  • Cyanobacteria Harmful Algae Blooms: Causes, Impacts, and Risk Management

    • Abstract: Abstract Cyanobacteria harmful algal blooms (cHABs) are increasingly becoming an emerging threat to aquatic life, ecotourism, and certain real estate investments. Their spontaneous yet sporadic occurrence has made mitigation measures a cumbersome task; moreover, current trends regarding anthropogenic activities, especially in agriculture and industry portend further undesirable events. Apart from the aesthetic degeneration they create in their respective habitats, they are equally capable of secreting toxins, which altogether present grave environmental and medical consequences. In this paper, we gave an update on factors that influence cHABs, cyanotoxin exposure routes, and environmental public health implications, especially impacts on fish, pets, and livestock. We discussed social economic impacts, risk assessment, and management problems for cHABs and, thereafter, assessed the extant management approaches including prevention, control, and mitigation of the proliferation of cyanobacterial blooms. In light of this, we suggest that more intensified research should be directed to the standardization of procedures for cyanotoxin analysis. Also, the provision of standardized reference material for the quantification of cyanotoxins is vital for routine monitoring as well as the development of strong in situ sensors capable of quantifying and detecting HABs cells and toxins in waterbodies to prevent the adverse impacts of cHABs. Also, more investigations into the natural and environmentally friendly approach to cyanobacteria management and the necessary and appropriate deployment of artificial intelligence are required. Finally, we wish to redirect the focus of public health authorities to protecting drinking water supply sources, agriculture products, and food sources from cyanotoxins contamination as well as to implement proper monitoring and treatment procedures to protect citizens from this potential health threat.

  • Effective Biosorption of Cesium and Strontium Ions from Aqueous Solutions
           Using Silica Loaded with Aspergillus brasiliensis

    • Abstract: Abstract In this study, the batch technique was used for the sorption of Sr(II) and Cs(I) onto silica loaded with Aspergillus brasiliensis (AB@S). The precipitation technique was used to synthesize the AB@S bio-sorbent, which was then evaluated using several analytical instruments such as XRD, FT-IR, and SEM. The results of this investigation revealed that the sorption process had a short equilibrium time (40 min). The distribution coefficient values have a sequence order Sr(II) ˃ Cs(I). AB@S sorbent has saturation capacity for Sr(II) and Cs(I) 72.2 and 26.1 mg g−1, respectively. The reaction kinetics follow the pseudo-second-order model with capacity values of 5.01 and 3.53 mg g−1 for Sr(II) and Cs(I), respectively. Applicability of Langmuir isotherms has capacity values of 66.3 and 23.38 mg g−1 for Sr(II) and Cs(I), respectively. Thermodynamics data are endothermic and spontaneous. The AB@S is a promising bio-sorbent for the removal of 85Sr and 134Cs from simulated radioactive waste (SRW). The investigation proved that the AB@S is suitable to adsorb Sr(II) and Cs(I) from aqueous solutions and could be considered potential material for the purification of effluent contaminated with these ions.

  • Determining Changes in Mangrove Cover Using Remote Sensing with Landsat
           Images: a Review

    • Abstract: Abstract Mangroves are ecosystems within the intertidal zone of tropical and subtropical coasts; they offer ecosystem services such as protection from coastal erosion and storms and flood control, act as carbon sinks and are also sources of income by providing various forest products. However, their cover is rapidly disappearing worldwide, which makes the diagnosis and monitoring of the state of these important ecosystems, as well as their restoration and conservation, a challenge. Remote sensing is a promising technique that provides accurate and efficient results in the mapping and monitoring of these ecosystems. The Landsat sensor provides the most used medium-resolution images for this type of study. The main objective of this article is to provide an updated review of the main remote sensing techniques, specifically Landsat satellite imagery, used in the detection of changes and mapping of mangrove forests, as well as a review of climatic and/or chemical factors related to changes in the spatial distribution of these ecosystems.

  • Assessment of PCR Inhibitor Removal Methods to Monitor Viruses in
           Environmental Water Samples: DAX-8 Outperforms Competitors

    • Abstract: Abstract Complex water matrices or viral elution buffers can interfere with the qPCR leading to an underestimation of the potential public health hazards of waterborne viral pathogens. Here, we assessed different approaches to mitigate inhibitory impact of complex water samples during RT-qPCR of murine norovirus (MNV), as an inhibition control. The dilution of extracted samples, the use of qPCR additives, a commercial PCR inhibitor removal kit, and polymeric adsorbents such as Supelite DAX-8 and polyvinylpyrrolidone (PVP) were all investigated in this context. Data indicated that the maximum amplification of MNV by RT-qPCR could be obtained by pre-dilution of samples. However, the dilution factor may depend on inhibitors concentration, primer length, probe sequence, and binding capacity. Interestingly, PCR inhibitor removal kits do not seem to be adequate for removing all PCR inhibitors. In comparison to other approaches studied here, the application of 5% DAX-8 led to an increase in MNV qPCR concentrations. DAX-8 can permanently eliminate humic acids from the extracted nucleic acids from the environmental water samples, and it has the potential to considerably improve the accuracy of the obtained non-detects and measured concentrations by qPCR. Further research is required to understand the performance of polymeric adsorbents with enveloped viruses.

  • Dynamic Transport and Distribution of Organic Pollutants in Water and
           Sediments of the Rur River

    • Abstract: Abstract The distribution and fate of organic pollutants within different compartments of a river system are determined by several key effects and drivers. Within the scope of this study, the aqueous and sedimentary compartments have been analyzed complementary to understand transport and accumulation pathways and to determine temporospatial effects. The bi-annual campaigns allow general statements to be made about relevant processes and effects on pollutant distribution. GC/MS non-target screenings revealed that there is only a minor group of contaminants that occur both in the water and in the riverbed. Nevertheless, for both phases, the main contamination with organic compounds occurred in the anthropogenic, middle to lower course of the river with loads up to 18.3 kg/d (2,4,7,9-tetramethyl-5-decyne-4,7-diol, TMDD) in the water and amounts up to 3.3 mg/gTOC (ƩEPA16 polycyclic aromatic hydrocarbons, PAHs) in the riverbed. Main emission sources were comparable, resulting in a high, almost constant contamination level which also contributes to the pollution of the superior, receiving river. Indeed, the pollution transport of the aqueous and sedimentary phases was closely connected, but with slight temporal and spatial heterogeneities. For the aqueous compartment, seasonal effects were identified while a remarkable change in riverbed contamination occurred due to an extreme flood event. However, dams within the catchment system cause a disconnection of the transport of lipophilic and hydrophilic substances. Overall, the combined investigation of different phases is an important aspect for a comprehensive view of river and environmental contamination.

  • Potentially Toxic Element (PTE) Sources in the Middle Eocene Carbonate
           Aquifer, East El Minia, Egypt

    • Abstract: Abstract Water pollution with potentially toxic elements (PTEs) becomes a major threat to the validity of that water for drinking and agriculture and hence human life. The current study aims to evaluate the carbonate aquifer groundwater PTE content, sources, and impact on water quality. To achieve this goal, drilling cutoff of two wells and 30 groundwater samples were collected and chemically analyzed. The groundwater has TDS values ranged from 271.2 to 971.8 mg/l. Freshwater recharge process led to the continuous freshening of the aquifer and enhanced the forward ion exchange reactions. Carbonate and evaporate mineral dissolution/precipitation processes are the main controller of groundwater chemistry. Cd and As represented the most hazardous elements in these rocks followed by Pb. The presence of high concentrations of PTEs (As, Cd, Cr, and Pb) in water-bearing carbonate rocks has led to detritus of water quality and its unsuitability for drinking owing to the occurrence of these harmful elements in water. Even though the high concentrations of PTEs in the studied water, these elements occurred in low mobility and toxicity species: Fe(OH)3, Mn2+, (HAsO4)−2, Cd2+, Cr2O3, Cu2O, CuO, and PbCO3. This reflects the importance of studying element species rather than total concentration. Even though the unsuitability of this water for drinking owing to high concentrations of some PTEs, all of the samples were found to be suitable for irrigation.

  • Growth Performance and Biochemical Composition of Desmodesmus sp. Green
           Alga Grown on Agricultural Industries Waste (Cheese Whey)

    • Abstract: Abstract Agricultural industries produce vast amounts of liquid waste, which contains a significant concentration of nutrients. In the context of emphasizing the huge increase in population, climate changes, and pollution which results in depletion of fresh water resources, a sustainable solution for a greener future is needed. Wastewater treatment by the use of microalgae can mitigate a part of the problem by restoring water for irrigating agricultural crops. Little studies give insights on the physiological responses and ultrastructure of the Chlorophyta alga Desmodesmus sp. as it grows in cheese whey (CW). The algal strain was mixotrophically grown in a growth medium composed of CW only and CW supported with Bold’s basal medium (BBM) for 14 days. The potent response was observed with algal cultures fed by 15% CW enriched with 50% BBM. Fifteen percent CW in combination with 50% BBM significantly improved Desmodesmus sp. growth (303%), productivity (325%), and accumulation of cell metabolites, mainly lipids (3.89%), and carbohydrates (1.95%). On the contrary, protein and photosynthetic pigment (chlorophyll a, chlorophyll b, and carotenoids) contents were higher in BBM than in all treatments. Fatty acid composition demonstrated that the predominantly accumulated fatty acids were palmitic (25.86%), oleic (35.31%), and linoleic acid (13.22%). In conclusion, Desmodesmus sp. can be a good candidate for phycoremediation when cultivated on CW, whereas it can reduce the nutrition costs and water demand of algal cultivation by 50% and 15%, respectively. Therefore, it may be an effective strategy for algal mass production in sustainable agricultural systems.
