  • Predict the particulate matter concentrations in 128 cities of China
    • Abstract: Abstract To predict the concentrations of PM2.5 and PM10 in the 128 cities of China, the discrete gray prediction model with fractional order accumulation (DFGM(1,1)) was used to predict the annual average PM2.5 and PM10 concentrations from 2019 to 2023. The result is as following: the annual average PM2.5 concentrations of Xi’an, Xuzhou, Ordos, Jingmen, Meizhou, Huizhou, Panzhihua, Kunming, Jixi, and Yichun are increasing from 2019 to 2023. The annual average PM2.5 concentrations in the 118 other cities are decreasing from 2019 to 2023. While the annual average PM10 concentrations of Taiyuan, Ordos, Dongguan, Karamay, Foshan, Yichun, Qitaihe, Jinzhou, and Heihe are increasing from 2019 to 2023, the annual average PM10 concentrations in the 119 other cities are decreasing from 2019 to 2023.

  • Differences in purifying and resistance tolerance ability of Scindapsus
           and Chlorophytum to formaldehyde pollution
    • Abstract: Abstract Formaldehyde is a major indoor air pollutant, and its removal decreases the health risk of urban inhabitants. Scindapsus and Chlorophytum are indoor plants that have been reported to remove formaldehyde. However, their ability to absorb formaldehyde, their resistance, and their morphological changes in response to formaldehyde absorption have not been reported to date. In this study, both Scindapsus and Chlorophytum were used as test materials and their phenotype, microscopic change, enzyme activity, gene expression, and ability to absorb formaldehyde were investigated in response to formaldehyde stress. The results showed that the ability of Chlorophytum to absorb formaldehyde was stronger than that of Scindapsus; moreover, the expression level of the ADH2 gene in Chlorophytum was significantly higher than in Scindapsus. However, Chlorophytum suffered more severe damage of the leaves than Scindapsus. The superoxide dismutase, peroxidase, and catalase enzyme activities of Chlorophytum were lower than those of Scindapsus in response to formaldehyde absorption. This showed that compared with Scindapsus, Chlorophytum had a strong ability to absorb formaldehyde but a weaker ability to tolerate formaldehyde. Based on these results, to purify formaldehyde pollution from indoor air, it is recommended to use the Chlorophytum. However, regular replacement of these damaged Chlorophytum plants should be implemented to retain a beautiful indoor environment.

  • Sustainable hybrid electric vehicle selection in the context of a
           developing country
    • Abstract: Abstract The ever increasing global warming is affecting both the environment and quality of life. The dependency on the usage of fossil fuels for transportation and power generation sector is harming the environment in terms of greenhouse gas (GHG) emissions. To limit the use of fossil fuel, the world has to move towards a renewable, clean, and economical form of energy. In the transportation sector, the paradigm shift towards electric mobility is a step towards the same goal. For a developing country like Pakistan, due to the lacking charging infrastructure, load shedding of electricity, and high cost of non-renewable electrical energy, a country like Pakistan cannot go dependent on fully electric vehicles (EVs). The country has to shift from normal internal combustion engine vehicles (ICEVs) to hybrid electric vehicles (HEVs). This paper aims to select the most sustainable HEV in the context of a developing country, Pakistan. Using the multi-criteria decision making (MCDM) technique, i.e., fuzzy Technique for Order Performance by Similarity to Ideal Solution (TOPSIS), based on ten criteria and seven alternatives, it has been found that Toyota Aqua outperforms among all the other alternatives in terms of economic, social, and environmental perspective. Furthermore, to move towards hybrid technology, the government has to give relaxation in terms of customs duty and should encourage auto manufacturers to set up local industries of such vehicles in the country.

  • Financial instability and CO 2 emissions: cross-country evidence
    • Abstract: Abstract In the energy economics literature, a few scientific studies are found on the topic of financial instability and environmental quality. The current study is an attempt to fill this gap by examining the association between financial instability, economic growth, energy consumption, trade openness, urban population and CO2 emissions in 54 developing economies using panel data from 1980 to 2016. For empirical analysis, we employ fixed effects, difference generalized method of moments (GMM) and system GMM estimator. Empirical evidence confirms that financial instability has a significant negative impact on CO2 emissions, whereas the increase in economic growth, energy consumption and urban population are harmful to the environment. The findings of this empirical study offer new outcomes for policymakers to design inclusive financial, economic and energy consumption strategies to reduce the adverse effect of environmental pollution.

  • Health-relevant ground-level ozone and temperature events under future
           climate change using the example of Bavaria, Southern Germany
    • Abstract: Abstract Relationships of larger scale meteorological predictors with ground-level daily maximum ozone (O3max) and daily maximum air temperature (Tmax) for stations in Bavaria were analysed. O3max and Tmax as well as threshold exceedances of these variables were assessed under the constraints of ongoing climate change until the end of the twenty-first century. Under RCP8.5 scenario conditions, a substantial increase of Tmax in the months from April to September arose, with a mean value of 5 K in the period 2081–2100 compared with the historical period 1986–2005. Statistical downscaling projections pointed to a mean O3max rise of 17 μg/m3. The frequency of threshold exceedances showed also large changes. Hot days may occur in the future at about 30% of all days. Exceedances of O3max > 100 μg/m3 were projected to increase to about 40% of all days at urban traffic sites and up to about 70% in the rural regional background. Days with O3max > 120 μg/m3 occurred still at about 20% of all days at urban traffic sites and at about 45% in rural regional background locations. With respect to combined Tmax > 30 °C and O3max > 100 μg/m3 events in the future, an occurrence of such events at about 27–29% of all days in the summer months from April to September was assessed. The increases were mainly associated with the strong temperature rise until the end of the century. In summary, the projected Tmax and O3max changes point to a considerable increased health burden in Bavaria until the end of the century, resulting from strong changes of both variables and their associated individual and combined impact on human health.

  • Population urbanization, trade openness and carbon emissions: an empirical
           analysis based on China
    • Abstract: Abstract The key to control carbon emissions is to clarify the cause of carbon emissions and their transfer process. This paper focuses on the relationship and its internal mechanism of population urbanization, trade openness and carbon emissions using the threshold model and the moderated mediating model, which is based on the panel data of China during 2003–2016. The results show that the higher the level of population urbanization is; the more carbon emissions are. There is a significant threshold effect on trade openness. That is, when the threshold value of urban population density is 24,211 people per square kilometer, the relationship between trade openness and carbon emissions is “inverted U”. The population urbanization can also affect carbon emissions through trade openness indirectly, and its moderated mediating effect is significant. The moderated variables can be divided into four categories: scale effect, structure effect, technological progress effect, and social effect. Different moderated variables have different effects on carbon emission path, but they show an effective tendency of controlling emissions on the whole. By quantifying the conditional indirect effect, this paper analyzes the internal channel of population urbanization, trade openness, and carbon emissions. Then, according to the characteristics of different moderated effects, the effective emission control policy in China will be formulated in the future.

  • Migraine headaches and fragranced consumer products: an international
           population-based study
    • Abstract: Abstract Fragranced consumer products, such as air fresheners and cleaning supplies, have been associated with health problems including migraine headaches. This study investigates the prevalence of migraines associated with exposure to fragranced products. Nationally representative population surveys (n = 4435) across four countries—the United States (US), Australia (AU), the United Kingdom (UK), and Sweden (SE)—found that, on average, 12.6% of adults report migraine headaches when exposed to fragranced products (15.7% US, 10.0% AU, 8.4% UK, 16.1% SE). Among those individuals, 43.2% report migraines from air fresheners or deodorizers, 15.0% from the scent of laundry products coming from a dryer vent, 39.9% from being in a room cleaned with scented products, 53.7% from being near someone wearing a fragranced product, and 45.7% from other types of fragranced products. Furthermore, 30.6% of these individuals have lost workdays or lost a job, in the past year, due to fragranced product exposure in the workplace. Findings from this study indicate that migraine headaches can be associated with fragranced consumer products, and that reducing exposure could reduce adverse health and societal effects.

  • Linking health impact and Post-environmental impact assessments: a case of
           municipal sewage treatment plant volatile organic compounds
    • Abstract: Abstract Deficiencies remain in current health impact assessment (HIA) and environmental impact assessment (EIA) projects. To address the shortcomings in EIA theory, a case of odors from a municipal sewage treatment plant (MSTP) was examined and geographic factors were employed to associate the spatial diffusion of the pollutants with the population’s activities based on land-use attributes. After screening the MSTP priority control pollutants, odors, hydrogen sulfide, and ammonia were selected for this study. Then, the spatial parameters for the pollutant simulation were surveyed, including parameters concerning the meteorological analysis, environmental emission monitoring, and emission source analysis, and a prediction of the pollutant diffusion as imaged and identified. The types of human social activity and exposure patterns were sorted as land-use attributes. An integration of the spatial diffusion of the pollutants with the exposure profiles of the scenario population according to the land-use attributes was achieved using counterpart spatial coordination factors. In our study, the commonly applied method of HIA risk calculation was followed and then extended by the spatial techniques introduced. The results of the scenario HIA contours are presented here, making it easy to determine the acceptable levels of the MSTP odor pollutants on a geographic scale. This study examines a significant approach to associate HIA with post-EIA via spatial factors and addresses the deficiencies of HIA in EIA empirical applications.

  • Vehicle atmospheric pollution evaluation using AERMOD model at avenue in a
           Brazilian capital city
    • Abstract: Abstract One of the most complex environmental problems is the air pollution, and automotive vehicles are one of the main sources of urban air pollution. Aracaju-SE, Sergipe’s capital in the northeast of Brazil, faces frequent congestion in traffic and does not have a monitoring network of air quality, so mathematical models are useful for impact assessment. This work consisted of an unusual application of AERMOD View software for vehicular pollution evaluation at Tancredo Neves Avenue in Aracaju’s city. The modeling was performed for the two avenue tracks, considered as urban linear sources. The rate of emission source was calculated from emission factors, average speed, and the number of vehicles accounted for footage circulating on the promenade at peak times. Concentrations distributions of total suspended particles (TSP), carbon monoxide (CO), and nitrogen oxide (NOx) on the mesh receptors were determinated from weather, topographic, and sources of emission data. The dispersion maps showed that the pollutants were concentrated around the sources; the estimated TSP concentrations were within the standards of CONAMA 491/2018 law. The CO concentration values exceeded the standard due to the high rate of emission sources. NO2 concentrations also exceeded the standard for hourly average, attributed to the contribution of heavy vehicles and the emission rates of light vehicles and motorcycles. The simulations showed that the meteorological and topographical conditions of Aracaju favor the atmospheric pollutants dispersion, that vehicles significantly affect air quality in the region and that the mathematical modeling is a useful tool for the study of atmospheric dispersion.

  • Association between PM 2.5 exposure and heart rate variability for the
           patients with cardiac problems in Japan
    • Abstract: Abstract A reduction in heart rate variability (HRV) is reportedly associated with an increased risk of cardiovascular mortality and morbidity. In previous studies, an inverse association was noted between HRV and particulate air pollution, but the sample populations were small and most consisted only of elderly individuals. We examined the association between 24-h HRV and fine particulate matter (PM2.5) in a large study population spanning 7 prefectures in Japan from April 2010 through March 2013. Meta-analysis was also performed. In total, 59,493 records of 24-h HRV for patients aged 20–90 years with symptoms/signs suggestive of heart disease were included in this analysis. Air pollution data were obtained from the National Institute for Environmental Studies. Regression models were used to examine the association between daily concentration of PM2.5 and HRV indices (e.g., standard deviation of normal-to-normal (SDNN), SD of average NN internals calculated over short periods (SDANN), very low frequency (VLF), and ultra-low frequency (ULF)). The model was adjusted for age, sex, temperature, and relative humidity. We examined the lagged association for single (up to lag3) and moving average (up to lag03). We found that decreases in HRV indices, especially for SDNN, SDANN, VLF, and ULF, were associated with PM2.5 in Hokkaido, Chiba, Tokyo, and Kanagawa. In contrast, there was no clear association between HRV with PM2.5 in Saitama and Aichi. Meta-analysis revealed significant decreases in SDNN, SDANN, VLF, and ULF were associated with PM2.5. Short-term exposure to PM2.5 was associated with lower 24-h HRV in patients with symptoms/signs suggestive of heart disease.

  • Exposure to respirable particles and TVOC in underground parking garages
           under different types of ventilation and their associated health effects
    • Abstract: Abstract Vehicle-induced pollutants in closed underground parking garages represent a major environmental issue influencing human health. In this study, the exposure to particulate matter (PM10, PM4, and PM2.5) and health risk assessments were analyzed using the lifetime average daily doses (LADDs) and cancer risks for selected volatile organic compounds (VOCs). Ventilation types and traffic volumes were used as parameters to characterize variations of the PM and total volatile organic compounds (TVOCs). In the investigated underground parking garage, the mass concentrations of PM10, PM4, and PM2.5 were 107.2–213.6, 78.4–138.3, and 56.2–102.4 μg m−3, respectively, and TVOC concentrations ranged from 523.0 to 1064.0 μg m−3 during the summer and winter seasons. Hourly PM2.5 concentrations during the daytime were higher than those measured at night, while no significant difference was observed between day and night for TVOC concentrations. The linear regressions for TVOC and traffic volume show that TVOC concentrations increased with increasing traffic. Among the I/O ratios for PM investigated during summer and winter, the only statistically significant difference was observed between natural and mechanical ventilation in parking garages. For all generated PMs, 72.2–80.1% of the aerosol deposition occurred in the head airways, while 4.8–5.1% of the total was deposited in the alveola and 2.5% in the tracheobronchial regions. The data presented herein suggest that, depending on ventilation types, the highest respirable particles generate in underground parking garage and deposit in all respiratory regions. The estimated cancer risks for car park users and occupational staff were determined, and possible and probable risks were measured.

  • Google Earth Engine–assisted black carbon radiative forcing calculation
           over a heavy industrial city in China
    • Abstract: Abstract Black carbon (BC) aerosol has a low content in the atmosphere; however, it has a strong radiative forcing effect and a significant impact on human beings and the environment. BC aerosol radiative forcing (ARF) has a major environmental influence. The main method to calculate the ARF is numerical simulation using a radiation transfer model by inputting atmospheric and surface parameters. Currently, most research studies directly apply the albedo products, which are not the real surface albedo (the blue-sky albedo). Alternatively, they use an empirical formula to calculate the sky diffuse light ratio to obtain the real surface albedo. To overcome these shortcomings, this study develops a new scheme to obtain the BC ARF in Xuzhou City from May 2014 to July 2016 by combining the BC mass concentration, albedo measurements from the Google Earth Engine (GEE) platform, aerosol optical depth (AOD), and microphysical parameters retrieved from the Aerosol Robotic Network (AERONET). Although BC AOD accounts for 3.3 to 17.9% of the total AOD, the BC ARF at the surface (SFC) and top of the atmosphere (TOA) is between − 14.06 ± 4.645 W/m2 and − 4.04 ± 0.437 W/m2 and between 2.93 ± 1.034 W/m2 and 0.74 ± 0.093 W/m2, with average values of − 9.67 ± 2.787 W/m2 and 2.02 ± 0.587 W/m2, respectively. Finally, comparing the BC ARF obtained by different albedo methods shows that the BC ARF change at the TOA is marked, and generally, the BC ARF calculated by the empirical formula method is lower than that calculated by using the blue-sky albedo method.

  • Investigating wintertime air pollution in Hangzhou, China
    • Abstract: Abstract Hangzhou, one of the most prosperous cities in China, suffered from severe air quality degradation in wintertime, and the ambient atmospheric particulate matter (PM) has become the most public-concerning air pollutant. In this work, a case study in wintry Hangzhou is made, for analysis of air pollutants and prediction of PM2.5/PM10 using two machine learning models, recurrent neural network (RNN) and random forest. The results signify that statistic-based and inventory-free machine learning is competently alternative to the inventory-predicted atmospheric models. Variable importance (VI) indicates that CO was the predominant factor for both PM2.5 and PM10. Dew-point deficit played an essential role in shaping gaseous air pollutants. Water vapor pressure and hydrostatic energy had trivial impact on atmospheric pollutants. RNN and random forest both show high accuracy in predicting PM2.5 and PM10. The inter-annual consistence of PM’s components is confirmed. A method to pinpoint whether the high episodes of PM were spawned by long-range transport or increase of gaseous pollutants (SO2, NO2, and CO) is proposed. Additionally, the possible chemical bond between CO and PM needs to be further investigated.

  • Analysis of an indoor air decontamination device inside an aerobiology
           chamber: a numerical-experimental study
    • Abstract: Abstract This study developed a computational fluid dynamics (CFD) model to assess the impact of the site of location of a commercial device (HEPA filter/ultraviolet light) on its capacity for microbial decontamination of indoor air. The three locations of the air decontamination device (ADD) in the aerobiology chamber were at the center, the middle of one of the lateral sides, and at the middle of the side in front of the axial air circulating fan. The findings were then compared to the experimental data generated in an earlier study on the same device using aerosolized Staphylococcus aureus as the challenge. The findings of the CFD model were strongly correlated to the experimental results, and the best site for the ADD was found to be at the middle of one of the lateral sides of the chamber. In this state, the microbial decontamination efficiency of the ADD was 99.46%. Additionally, this modeling study identified (a) the device’s optimal location in the chamber for microbial decontamination and the device’s effectiveness, (b) the axial fan’s location and its ability to uniformly distribute the airborne bacteria inside the chamber, and (c) suitability of the air samples collecting from the chamber’s center. The incorporation of this model could boost the design and construction of the chamber, reduce the need for laboratory experimentation, and also help to simulate and investigate an ADD’s efficacy for maximum reduction of airborne pathogens.

  • Comparison of biomass burning tracer concentrations between two winter
           seasons in Krynica Zdrój
    • Abstract: Abstract Biomass burning is one source of air pollution that emits soot, smoke, particulate matter, free radicals and other substances, affecting human health, air quality, cloud formation processes and climate change. During biomass burning, organic biomass burning tracers are emitted, such as levoglucosan and its isomers mannosan and galactosan, which are formed at temperatures above 300 °C during cellulose and hemicellulose pyrolysis. The objective of this research is the measurement of biomass burning tracer concentrations in PM10 samples in Krynica during two winter seasons from 01.12.2017 to 31.03.2018 and from 01.12.2018 to 26.03.2019. The average concentrations of organic carbon were 9.48 μg/m3 in the 2017/2018 season and 8.79 μg/m3 in the 2018/2019 season. The average concentration of levoglucosan in the PM10 samples in 2017/2018 was 137 ng/m3, while in 2018/2019, the average concentration reached 245 ng/m3. Levoglucosan was the dominant compound among the determined biomass burning tracers, accounting for 88.6% in 2017/2018 and 72.4% in 2018/2019. The conducted measurements show that the levoglucosan to mannosan ratio was equal to 10.5 and 3.9 in 2017/2018 and 2018/2019, respectively. The biomass smoke organic carbon was approximately 10.6% in 2017/2018 and 20.5% in 2018/2019. These results correspond to the contribution of biomass smoke to organic carbon, which was equal to 14.4% and 28.4% in the 2017/2018 and 2018/2019 seasons, respectively.

  • Impact of regional versus local resolution air quality modeling on
           particulate matter exposure health impact assessment
    • Abstract: Abstract As much of the population lives in close proximity to high-traffic roads, there is the potential for health impact assessments based on regional air quality modeling to underpredict health impacts. We compare the estimated health impacts from fine particulate matter (PM2.5) using local (0.04 × 0.04 km upscaled to census block group resolution) compared to regional (12 × 12 km resolution) modeled concentrations for three locations in Connecticut: Hartford, New Haven, and Willimantic. We use concentration estimates from the Comprehensive Air Quality Model with Extensions (CAMx) regional model and a hybrid model combining CAMx with a near road model (HYCAMR) in the Environmental Benefits Mapping and Analysis Program—Community Edition (BenMAP-CE) to calculate the difference in estimated human health impacts using different resolution air quality estimates from PM2.5 exposure including mortality, emergency room visits, hospitalizations, and asthma exacerbation. This provides an estimate of the potential underprediction of health impacts resulting from not accounting for the sharp concentration gradients in near road environments in urban areas. The fine-scale estimates capture the elevated concentrations near the roadways leading to increased estimates of overall mortality and morbidity in the population. We find an increase in the estimated likelihood of emergency department visits and mortality in the urban core. We also compare the impact of model resolution on the health impact estimates for different demographic groups. Of the locations investigated, we see the largest differences between demographic groups in Willimantic, CT. Our results indicate that using regional air pollutant concentrations may lead to an underprediction of human health impacts from air pollution exposure.

  • Association between traffic emissions mixed with resuspended dust and
           heart rate variability among healthy adults in Delhi
    • Abstract: Abstract Aerosol emissions from vehicles have been linked to changes in heart rate variability (HRV) parameters of the susceptible population in developed countries. In the present study, the effects of vehicular emission and resuspended road dust on HRV parameters in healthy adults (18–43 years of age) were assessed at Delhi, India, a metro city where the world’s largest youth population 356 million of age group 10–24 years resides as per census report of 2011. The study presents personal exposure concentration of fine particulate matter (PM1 and PM2.5) at a road site in Delhi and its link with the changes in HRV parameters. The mixed effect model treated particulate matter (PM) mass concentration, age of participants, body mass index, and climatic parameters (ambient temperature and relative humidity) as independent variables and HRV parameters as dependent variables. The observed data showed that per inter quartile range (IQR) increase in PM1 resulted in a considerable decrease in the HRV indices: percentage of successive NN-intervals that differ from each other by greater than 50 ms (pNN50) [− 26.6% (− 40.52, − 1.29)], root mean square of differences between successive NN-intervals (r-MSSD) [− 9.8% (− 17.53, 1.32)] and high-frequency power (HF) [− 15.6% (− 27.61, 2.89)], and considerable increase in low frequency (LF) by HF ratio [24.0% (0.95, 45.39)]. Greater changes were seen in most of the HRV parameters for PM2.5 as compared to PM1, probably due to the presence of fine dust along with vehicle emissions which aggravate the effect. The change in HRV parameters is considered as a powerful and independent predictor of changes in cardiac autonomic nervous system. The trend observed in the present study was in congruence with that observed in previous studies except for LF, and the reductions in HRV indices were well within the range when compared with literature. But still the impact on HRV was significant which raises a concern for the healthy population which forms a large portion of the society. Also, in light of the limited evidence on the effect of PM1 on cardiac health, the present study summarized that PM1 has a significant impact on HRV too which is of concern due to its high contribution to total PM.

  • Mitigating the impacts of air pollutants in Nepal and climate co-benefits:
           a scenario-based approach
    • Abstract: Abstract Short-lived climate pollutants (SLCPs) including black carbon (BC), methane (CH4), and tropospheric ozone (O3) are major climate forcers after carbon dioxide (CO2). These SLCPs also have detrimental impacts on human health and agriculture. Studies show that the Hindu Kush Himalayan (HKH) region, which includes Nepal, has been experiencing the impacts of these pollutants in addition to greenhouse gases. In this study, we derive a national-level emission inventory for SLCPs, CO2, and air pollutants for Nepal and project their impacts under reference (REF) and mitigation policy (POL) scenarios. The impacts on human health, agriculture, and climate were then estimated by applying the following: (1) adjoint coefficients from the Goddard Earth Observing System (GEOS)-chemical transport model that quantify the sensitivity of fine particulate matter (PM2.5) and surface O3 concentrations in Nepal, and radiative forcing in four latitudinal bands, to emissions in 2 × 2.5° grids, and (2) concentration–response functions to estimate health and crop loss impacts in Nepal. With the mitigating measures undertaken, emission reductions of about 78% each of BC and CH4 and 87% of PM2.5 could be achieved in 2050 compared with the REF scenario. This would lead to an estimated avoidance of 29,000 lives lost and 1.7 million tonnes of crop loss while bringing an economic benefit in present value of 2.7 times more than the total cost incurred in its implementation during the whole period 2010–2050. The results provide useful policy insights and pathways for evidence-based decision-making in the design and effective implementation of SLCP mitigation measures in Nepal.

  • Effectiveness of an air quality intervention: an accountability study in a
           highly polluted industrial town
    • Abstract: Abstract Public interventions to reduce industrial emissions and improve air quality are particularly necessary in areas that suffer an environmental and health emergency. Taranto (Apulia region, Southern Italy) is one of the most industrialized cities in Southern Italy due to the massive presence of industrial sites, including a huge steel plant. The latter hosts a large open-air mineral deposit, whose dust strongly impacts the Tamburi neighborhood, downwind of the plant when the wind blows north-wester. In order to reduce the PM10 (particulate matter) and B(a)P (Benzo(a)pirene) concentrations in this neighborhood, the Apulia Region enacted a law restricting some industrial activities during certain meteorological situations, called wind days, characterized by strong north-westerly winds. Connected to the regional law, there was a Local Health Unit warning to the Tamburi population to ventilate indoor environments during the central hours of the day. The aim of this work is to assess the effectiveness and the appropriateness of the intervention implemented and to evaluate whether it effectively improved the air quality in the neighborhood close to the mineral deposit. Time-space statistical analysis of PM data measured by the fixed monitoring network before and after the intervention period was carried out. The analysis was performed for different meteorological conditions, different wind days characteristics (long/short), time periods, and other pollutants such as PAH (polycyclic aromatic hydrocarbon), which includes B(a)P for which measurements were not available. In the area closest to the industrial area, there was a reduction in the difference between the concentration of PM10 on wind days and those in other weather conditions. The reduction was more consistent on long, persistent wind days, when the difference in concentrations reduced from 13.3 to 3.9 μg/m3. However, the uncertainties regarding the wind days predictions suggest that the PM reduction may only partially be attributed to the regional law. Furthermore, the analysis of the PAH showed that there are weather conditions other than wind days that lead to a deterioration in the air quality in the neighborhood. Regarding the warning given by local health authorities to protect the population from dust injuries, the wind days daily PM10 profiles do not evidence a sharp reduction during the selected time slot, while other industrial pollutants clearly increase in the same time slot. Overall, results evidence the partiality of the intervention and call for a more comprehensive emissions plan to reduce their impact on air quality. In general, the study shows the need to periodically evaluate the effectiveness of any intervention and to take the consequent decisions to adapt them.

  • Chemical and sulfur isotopic characteristics of precipitation in a
           representative urban site, South China: implication for anthropogenic
           influences
    • Abstract: Abstract Nanchang, the capital of Jiangxi Province, is a major constituent of the South China Acid Rain Zone. In this study, the chemical and sulfur isotopic compositions of precipitation in this region were investigated during 2015–2016 to clarify the origin of major chemicals. The pH was < 5.6 for 72.6% of precipitation events, reflecting the predominance of acid rain. SO42−, Ca2+, NH4+, and NO3− were the four main ions, occupying 77% of the total ions in precipitation. SO42− and NO3− were the dominant acidifying species while Ca2+ and NH4+ were the dominant neutralizing species. Overall, the concentrations of ions in precipitation were lower in the rainy months than in other months. Compared with foreign cities, the concentrations of ions in precipitation, particularly SO42− and NO3−, were significantly higher in Nanchang, indicating the effect of anthropogenic pollution. Factor analyses showed that in precipitation, anthropogenic pollutants controlled SO42−, NO3−, and NH4+ whereas K+, Mg2+, and Ca2+ originated from rock weathering, and Cl− was dominantly of marine origin. Based on the sulfur isotope data, it was further found that precipitation SO42− was associated with the use of northern Chinese coal in Nanchang and homogeneous oxidation was a major mechanism affecting δ34S fluctuations in precipitation SO42− with time. This work provides deep insights into the formation of acid rain and is helpful for guiding air quality protection in South China.
