  • Assessment of indoor air pollutant concentrations and emissions from
           natural gas cooking burners in residential buildings in Tehran, Iran
    • Abstract: Abstract The effect of natural gas cooking burner usage on time-dependent concentrations of carbon monoxide (CO), nitrogen dioxide (NO2), and formaldehyde (HCHO) in homes in Tehran was estimated using a mass balance model. The outdoor air concentrations were considered the only background sources of indoor concentrations of CO and NO2, and indoor concentration of HCHO was calculated without considering any background sources. The contributions of the natural gas cooking burner use to the indoor concentrations of CO and NO2 in the residential buildings were significantly affected by season and municipal region and estimated to be 13% (95% uncertainty interval (UI) 8–42) and 26% (15–45), respectively. The annual average indoor concentrations of CO, NO2, and HCHO in the residential buildings were 3431 (2308–6863), 87 (56–169), and 3 (1–20) μg/m3, respectively. Although the average indoor concentrations of all the pollutants were within the permissible range, the upper limits of 95% UI of 24-h average CO and 1-h average NO2 concentrations were higher than the WHO guidelines in 41% and 25% of the cases, respectively. The most efficient measures for control of people’s high exposure to the pollutants from natural gas burners were determined to be partial or total replacement of natural gas burners with electric burners, using the range hood during cooking, reducing frequency and duration of natural gas burner, optimizing ventilation rate, and increasing people awareness about air pollutants emitted by natural gas burners that should be taken with more consideration.

  • 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.

  • Concentrations of bacteria and bacterial and fungal spores calculated from
           chemical tracers associated with size-segregated aerosol in a composting
           plant
    • Abstract: Abstract The lack of information on biological risks in workplaces arises from the difficulty to measure bioaerosol. This study aimed to develop and improve the bioaerosol monitoring technique that uses proper biomarkers as a tool. Muramic and dipicolinic acids, and ergosterol were used as tracers for bacteria cells, bacterial spores, and fungal spores, respectively. Furthermore, 12- and 13-methyltetradecanoic acids (iso- and anteiso- C15:0) were used to study the presence of airborne bacteria and 3-hydroxy fatty acids were used to determine the concentration of peptidoglycan. Airborne particulate matter was sampled in a municipal indoor waste composting facility by multistage impactor samplers, during three main stages of composting process. The microorganism content, in airborne particles with aerodynamic diameter minor then 1 μm and between 1 and 10 μm, was determined starting from the aforementioned biomarker concentrations. For iso- and anteiso- C15:0, a conversion factor to transform its concentration into bacterial content was tentatively proposed. The results show that the chemical method covers some gaps in the information about bioaerosol presence in polluted atmospheres. Differences up to two orders of magnitude are observed, by comparing the results obtained by biomarkers and by cultivation-dependent methods. The microbial content, expressed as a percentage by mass on respect the PM, ranged from 4 to 28% with higher percentages during shredding and mixing stages and lower values during biocell opening operations. Bacterial spores, bacterial cells, and fungal spores detected were high in number, compared with the findings in similar studies elsewhere.

  • 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.

  • Estimation of local daily PM 2.5 concentration during wildfire episodes:
           integrating MODIS AOD with multivariate linear mixed effect (LME) models
    • Abstract: Abstract Seasonal peaks of air pollution from wildfires are increasing in frequency and severity in the western provinces of Canada. During these episodes, populations are exposed to adverse short-term health effects due to elevated levels of fine particulate matter, which is the primary pollutant associated with smoke. The spatial resolution of ground-based monitoring records generally is not sufficient for emergency preparedness and epidemiological studies of such events. Accurate spatial and temporal models of smoke pollution for the study of smoke exposure effects require reliable, fine-scale input data. Satellite aerosol optical depth (AOD) measures can provide a valuable alternative to the coarse spatial resolution of ground PM2.5 monitoring network measurements. Numerous statistical approaches have been used to estimate the link between AOD and PM2.5, most of which consider the relationship between AOD and PM2.5 as being fixed over space and for an entire day; however, due to time-varying meteorological variables, that relationship changes over time and space. Hence, to capture the effects of temporal and spatial variations on the AOD-PM2.5 relationship, two nested linear mixed effect (LME) models are developed herein. Daily estimation of PM2.5 concentration is derived by incorporating nested period-zone-specific random effects of the AOD-PM2.5 relationship over the province of Alberta, Canada. Model validation shows that LME improves the estimation performance of the model compared with ordinary multivariate linear regression by more than 115%. Our findings indicate that the potential of the LME model increases when additional variables are integrated with AOD measures in a multivariate framework. This single model yields an array of reliable spatial-temporal estimates of daily PM2.5 concentrations from wildfire at fine spatial resolution.

  • PM 2.5 concentration forecasting using ANFIS, EEMD-GRNN, MLP, and MLR
           models: a case study of Tehran, Iran
    • Abstract: Abstract Tehran, the capital city of Iran, is among the world’s most polluted cities. Tehran is exposed to different types of pollutants, one of which is the suspended particles of PM2.5. One of the steps that should be taken to reduce hazardous effects of this pollution on the health of society is timely prediction and announcement of its increased levels. Different methods can be used for predicting PM2.5 concentration. This study used a variety of models for predicting PM2.5 concentrations, including linear, nonlinear, and hybrid models. More specifically, the models which were used consisted of multiple linear regression, multi-layer perceptron (nonlinear model), and a combination of ensemble empirical mode decomposition and general regression neural network (EEMD-GRNN) and Adaptive Neuro-Fuzzy Inference System (ANFIS) (hybrid of nonlinear models). The independent variables in the current study were air quality parameters, which were measured in reference to PM2.5, PM10, SO2, NO2, CO, and O3 and meteorological data which included average atmospheric pressure (AP), average maximum temperature (Max T), average minimum temperature (Min T), daily relative humidity level of the air (RH), daily total precipitation (TP), and daily wind speed (WS) in 2016 in Tehran. The results indicated that the ANFIS model exhibited the most accurate prediction in the training phase (R2 = 0.99, RMSE (root mean square error) = 0.4794 and MAE (mean absolute error) = 0.1305) and in the testing phase (R2 = 0.82, RMSE = 3.2979 and MAE = 2.1668). As it can be concluded, in comparison with a linear model, hybrid models are of higher precision in predicting PM2.5 concentration.

  • 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.

  • Does higher education system moderate energy consumption and climate
           change nexus' Evidence from a small island
    • Abstract: Abstract This study estimates the effects of higher education development on climate changes through energy consumption in the case of Cyprus (North), which progressed successfully in this sector although countries other than Turkey do not recognize its state (Turkish Republic of Northern Cyprus). The results of this study reveal that there is strong evidence for the positive and significant impact of higher education growth on climate change via energy consumption. Therefore, it is concluded that educational development in Cyprus is a long-term contributor to the energy sector and, therefore, climate change.

  • Indoor air pollution and respiratory health effects in inner city children
           with moderate to severe asthma
    • Abstract: Abstract Indoor air pollution is increasingly recognized as a significant risk for respiratory illness, particularly in vulnerable populations. Thirty-six children aged 6–14 years with moderate/severe asthma from inner city areas in New York City were studied for 2-week periods (summer and winter) using diaries and spirometry. Seven-day integrated indoor samples of PM10, PM2.5, trace elements, elemental/organic carbon, black carbon, and criteria gases (NO2, SO2, and O3) were collected in the subjects’ residences. Asthma outcomes included cough and wheeze severity, albuterol use, and pulmonary function. Mixed effects regression models for longitudinal data were used to relate weekly indoor pollutant concentrations to asthma outcomes. Odds ratios (ORs) were calculated for ordinal outcomes. During winter, significant positive associations for average weekly symptom severity scores were seen for NO2 (OR = 2.83; p = 0.02), calcium (OR = 3.29; p = 0.02), and silicon (OR = 3.64; p = 0.04). In summer, chlorine was associated with average weekly symptom scores (OR = 1.85; p = 0.004). Average albuterol puff use per day in winter was associated with NO2 (OR = 5.89; p = 0.009), nickel (OR = 2.27; p = 0.05), and silicon (OR = 5.59; p = 0.05). Albuterol use was not associated with indoor pollutants in summer. Asthma severity was associated with specific indoor pollutants. Seasonal differences were observed by pollutant and by clinical index studied.

  • A novel hybrid model for multi-step daily AQI forecasting driven by air
           pollution big data
    • Abstract: Abstract Air pollution is considered as a serious issue for the society and economy. Air pollution forecasting can offer a timely and effective early warning. In the current mainstream studies, the information from high-resolution air pollution data is usually ignored. In this study, the useful information from high-resolution big data (1 h) is utilized sufficiently. In the proposed model, high-resolution data (1 h) of different air pollution indices (AQI, PM2.5, PM10, SO2, NO2, O3, and CO concentrations) are utilized to enhance the performance, including 7 × 24,000 data samples. Besides, the variational mode decomposition (VMD) and the least absolute shrinkage and selector operation (LASSO) are proposed to preprocess and reshape the input data. The stacked auto-encoder (SAE) is proposed to reduce dimension and extract features. The deep echo state network (DESN) is trained to generate daily forecasting results. The high-resolution input is converted to low-resolution output in this way. Air pollution data of four polluted Chinese cities are utilized to verify the effectiveness, stability, and universality of the proposed model. The proposed model can outperform low-resolution forecasting models and other benchmark models.

  • Air pollution: impact and interventions
    • Abstract: Abstract Clean air is a fundamental requirement for the existence of life on earth. However, with the rapid rate of economic development, globalization, and increasing energy demand, large amount of emissions and waste are generated, leading to severe air pollution. This paper surveys the literature to provide an overview of the impact of air pollution on various aspects of human life. The impact is categorized broadly into health and socio-economic aspects and further subcategorized into multiple dimensions of health and socio-economic consequences. The survey reveals that the impact of air pollution is comprehensive, ranging from chronic to life-threatening diseases, and from malfunctioning of specific organ systems to subjective well-being. Additionally, evidence of the impact of air pollution on unexpected dimensions such as housing prices, larger economy, academic outcomes, and more is uncovered, leaving no doubt on the need to address this problem with the attention of the highest order. This evidence can be used to trigger more research and give policy-makers a starting point for clean-air campaigns. Merely highlighting the seriousness of the issue is not enough, and hence the paper also surveys the broader literature to identify interventions for clean air developed by public and private stakeholders across the world. While none of them may be ripe for blind duplication, this paper aims to provide decision-makers and researchers a bouquet of solutions to choose from while developing clean air programs and research agenda.

  • Use of two-point models in “Model choice in time-series studies of air
           pollution and mortality”
    • Abstract: Abstract In this work, a new technique is proposed to study short-term exposure and adverse health effects. The presented approach uses hierarchical clusters with the following structure: each pair of two sequential days in 1 year is embedded in the year. We have 183 clusters per year with the embedded structure <year:2 days>. Time-series analysis is conducted using a conditional Poisson regression with the constructed clusters as a stratum. Unmeasured confounders such as seasonal and long-term trends are not modelled but are controlled by the structure of the clusters. The proposed technique is illustrated using four freely accessible databases, which contain complex simulated data. These data are available as the compressed R workspace files. Results based on the simulated data were very close to the truth based on the presented methodology. In addition, the case-crossover method with 1-month and 2-week window, and a conditional Poisson regression on 3-day clusters as a stratum, was also applied to the simulated data. Difficulties (high type I error rate) were observed for the case-crossover method in the presence of high concurvity in the simulated data. The proposed methods using various forms of a stratum were further applied to the Chicago mortality data. The considered methods have often different qualitative and quantitative estimations.

  • Solar radiation attenuation by aerosol: application to solar farms
    • Abstract: Abstract The use of solar energy requires precise insolation knowledge of the considered site. Solar irradiance depends on geographical and astronomical parameters and variable characteristics of the atmosphere such as aerosol or cloud charge, which has a very important attenuation and pollution role. This study presents the estimate of the annual insolation of sites close to several solar farms. Insolation is calculated from Iqbal’s basic formulas with introduction of the total optical thickness determined by the AERONET. The PSDs and aerosol loading on an atmospheric column allowed the establishment of the attenuation-aerosol concentration relationship. The cloudless atmosphere attenuates the incident solar flux by an annual average of the order of 23.5%, where in average, about 13.73% is attributed to the aerosol, 17.75% for solar farm sites near the Sahara, and 8% for California and Arizona US sites.

  • A likely increase in fine particulate matter and premature mortality under
           future climate change
    • Abstract: Abstract Climate change modulates the concentration of fine particulate matter (PM2.5) via modifying atmospheric circulation, temperature, and the hydrological cycle. Furthermore, PM2.5 is associated with cardiopulmonary diseases and premature mortality. Here, we use seven models to assess the response of PM2.5 to end of the twenty-first century climate change under Representative Concentration Pathway 8.5, and the corresponding impact on premature mortality. The majority of models yield an increase in both PM2.5 and premature mortality associated with lung cancer and cardiopulmonary disease in all world regions except Africa. These results are robust across five different future population projections, although the magnitude of premature deaths can vary by up to a factor of two. Much larger uncertainty is related to uncertainty in model physics and the representation of aerosol processes. Although our analysis requires several assumptions related to future population estimates, as well as the concentration-response function, results suggest that future emission reductions are necessary to avoid the likely health risks associated with increasing PM2.5 in a warmer world.

  • Spatiotemporal assessment of mortality attributable to ambient PM 2.5
           exposure in Taiwan during 2008–2015
    • Abstract: Abstract In this study, we quantified the spatiotemporal burden of mortality attributable to ambient fine particulate matter (PM2.5, which is defined as a mass of particles with an aerodynamic dry diameter of ≤ 2.5 μm) in Taiwan during 2008–2015. Hourly concentrations of PM2.5 were obtained from the Taiwan Air Quality Monitoring Network. According to geographical and climatic characteristics, the Taiwan Environmental Protection Administration has divided Taiwan into seven air quality regions (AQRs): the North (four districts), Chu-Miao (two districts), Central (three districts), Yun-Chia-Nan (three districts), Kao-Ping (two districts), Yilan (one district), and Hua-Tung (two districts) regions. Demographic information and mortality data were acquired from the Department of Household Registration and National Death Registry of Taiwan, respectively. The World Health Organization’s (WHO) AirQ+ software was used to estimate the mortality attributable to exposure to PM2.5 for specific causes of deaths, specifically from ischemic heart disease (IHD), cerebrovascular disease (stroke), lung cancer (LC), and chronic obstructive pulmonary disease (COPD). The results indicated that nationally, the annual mean concentration of PM2.5 decreased from 2008 (30.75 μg m−3) to 2015 (20.07 μg m−3). Moreover, the population-attributable fraction (PAF) of cause-specific mortality due to PM2.5 exposure for IHD, stroke, LC, and COPD decreased from 21.72%, 30.31%, 15.97%, and 13.04%, respectively, in 2008 to 17.40%, 18.18%, 10.77%, and 9.09%, respectively, in 2015. Geographic variation was observed in the PM2.5 concentration and PAF. High PM2.5 levels and PAF of mortality due to PM2.5 were observed in southwestern and central Taiwan. Moreover, cardiovascular and cerebrovascular disease (IHD and stroke) accounted for the majority of the premature deaths related to PM2.5. Stroke was the largest contributor in PM2.5-related premature mortality; however, IHD instead of stroke became the largest contributor in the Yilan AQR in 2010, 2012, and 2014–2015 and in the Hua-Tung AQR in 2012–2015 with relatively low PM2.5 levels (less than 19 μg m−3). In Taiwan, ambient PM2.5 contributed substantially to the burden of disease. Our results could aid authorities in determining the effectiveness of current air pollution control strategies and plans.

  • Aspergillus spp. burden on filtering respiratory protective devices. Is
           there an occupational health concern'
    • Abstract: Abstract There is scientific evidence that associates occupational exposure to fungi in the waste industry to health outcomes, being Aspergillus genera reported as the most prevalent. During Filtering Respiratory Protective Devices (FFR) use, humidity and temperature conditions provide favorable conditions for Aspergillus growth. The aim of this study was to characterize Aspergillus burden retained by FFR interior layer and exhalation valve. The sample consisted of 120 FFR and the correspondent interior layer and exhalation valves collected from different workstations from one waste sorting industry. The fungal content of exhalation valve and from the interior layer of the each FFR was extracted and inoculated on malt extract agar (MEA) supplemented with chloramphenicol (0.05%) and dichloran-glycerol agar (DG18). FFR extracts were also used for the molecular detection of Aspergillus sections Flavi and Fumigati. Valves presented Aspergillus spp. as the most prevalent genera on MEA media (44.4%), unlike what was observed in the FFR interior layer, where Aspergillus spp. was not the most prevalent genera (6.84% MEA; 5.2% DG18). Among the Aspergillus genera, section Fumigati was the one with highest prevalence, both in exhalation valves (76.57% MEA; 87.24% DG18) and interior layer (75.81% MEA; 51.22% DG18). qPCR analysis successfully amplified DNA from the Aspergillus sections Flavi and Fumigati. Interior layers presented statistically significant differences showing higher number of FFR contaminated with higher levels of Aspergillus in the workstations where workers contact directly with waste. This work, revealing strong fungal contamination of FFR used by workers at waste industry, clearly indicates that future trials to test FFR protective efficacy and establishment of times for FFR replacement should be performed.
