Abstract
This study aims to explore the acute effects of short-term exposure to PM2.5 components and their mixture on PROM. Counts of hospital admissions due to PROM were collected at the Fourth Hospital of Shijiazhuang. The associations between the PROM and PM2.5 components was examined using a time-stratified case-crossover approach. The overall effects of components on TPROM were examined using the BKMR. During the study period 30,709 cases of PROMwere identified. The relative risks and the 95% CI of TPROM were 1.013 (1.002, 1.028) and 1.015 (1.003, 1.028) associated with per interquartile range increase in nitrate and ammonium ion on the current day and they were 1.007 (1.001, 1.013) and 1.003 (1.000, 1.005) on the previous day. The results from the BKMR models showed a higher risk of TPROM was associated with exposure to mixtures, in which, nitrate and organic matter were the main contributors to the overall effect.

Abstract
Urban air contamination is one of the ten most dangerous parameters for human health, which causes cardiovascular disease, respiratory, metabolic diseases, and decreased lung function. Air Q is a reliable software for studying the impacts of atmospheric contaminants on human health, and today, it is widely used in the environment. The purpose of this research was to quantify the mortality and morbidity rates that corresponded to ambient particulate matter (PM) in Rigan City. To perform this, the Air Q software was used. The findings reflected that the yearly mean values of PM10 and PM2.5 are 264.83 and 50.45 μg/m3. The findings indicated that the PM10 and PM2.5 content in Rigan was above standard levels described by WHO. The total number of deaths, cardiovascular deaths, and respiratory deaths due to PM in Rigan were estimated as 70.3, 45.8, and 10.7 persons, respectively. Hospital admissions for cardiovascular and respiratory diseases correlated to PM10 were estimated at 154.2 and 59 persons, respectively. Acute myocardial infarction associated with PM2.5 was 2.7 persons. Overall, the data in this study may be helpful to national and regional policymakers who are responsible for managing and preventing atmospheric contamination and assessing the costs of health risks.

A Review of Studies Using Air Q Software for Prediction of Air Pollution Health Effects in Iran. Curr Environ Health Rep 2022; 9:386-405.

Abstract
PURPOSE OF REVIEW Exposure to air pollutants may lead to various health effects and is a major public health issue. Concerns about these effects exist in both developed and developing countries. The Air Q software was developed to estimate the health impacts of air pollution based on reported levels of air pollutants in real world studies. In Iran several studies have been conducted to estimate human morbidity and mortality based on this software. We conducted this review to summarize articles which have predicted the effects of air pollution on human health in Iran using Air Q. We conducted a systematic search for relevant studies published until 24 April 2021 in Web of Science, PubMed, Scopus, and SID (Scientific Information Database which includes articles in Farsi language). We applied no time or language restrictions. RECENT FINDINGS A total of 44 studies out of 525 identified articles met our inclusion criteria. The main air pollutants under investigation were particulate matter (PM), NO2, O3, and SO2. Most studies were conducted in metropolitan areas, such as Ahvaz (9 studies), Tehran (9 studies), and Shiraz (7 studies). In all studies, the levels of most air pollutants were higher than the 2005 WHO guideline levels and were predicted to be related to considerable health effects. However, it was not possible to aggregate the results and report the total number of casualties during these years, because studies were done in different cities with fluctuating levels of multiple pollutants and in different years and time frames. This systematic review showed that air pollution remains at unacceptably high levels resulting in substantial detrimental health effects in various Iranian cities. Using clean renewable energies, increasing human capital, and increasing green spaces and vegetation can help improve air pollution and decrease human casualties in Iran.

The prospective effects of long-term exposure to ambient PM 2.5 and constituents on mortality in rural East China. CHEMOSPHERE 2021; 280:130740. [PMID: 34162086 DOI: 10.1016/j.chemosphere.2021.130740] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Revised: 04/25/2021] [Accepted: 04/28/2021] [Indexed: 06/13/2023]
Abstract
Few cohort studies explored the associations of long-term exposure to ambient fine particulate matter with an aerodynamic diameter of 2.5 μm or less (PM2.5) and its chemical constituents with mortality risk in rural China. We conducted a 12-year prospective study of 28,793 adults in rural Deqing, China from 2006 to 2018. Annual mean PM2.5 and its constituents, including black carbon (BC), organic carbon (OC), ammonium (NH4+), nitrate (NO3-), sulfate (SO42-), and soil dust were measured at participants' addresses at enrollment from a satellite-based exposure predicting model. Cox proportional hazard model was used to estimate hazard ratios (HRs) and 95% confidence intervals (95%CIs) of long-term exposure to PM2.5 for mortality. A total of 1960 deaths were identified during the follow-up. We found PM2.5, BC, OC, NH4+, NO3-, and SO42- were significantly associated with an increased risk of non-accidental mortality. The HR for non-accidental mortality was 1.17 (95%CI: 1.07, 1.28) for each 10 μg/m3 increase in PM2.5. As for constituents, the strongest association was found for BC (HR = 1.21, 95%CI: 1.11, 1.33), followed by NO3-, NH4+, SO42-, and OC (HR = 1.14-1.17 per interquartile range). A non-linear relationship was found between PM2.5 and non-accidental mortality. Similar associations were found for cardio-cerebrovascular and cancer mortality. Associations were stronger among men and ever smokers. Conclusively, we found long-term exposure to ambient PM2.5 and its chemical constituents (especially BC and NO3-) increased mortality risk. Our results suggested the importance of adopting effective targeted emission control to improve air quality for health protection in rural East China.

Abstract
Previous studies have proved that particulate air pollution was related to adverse cardiovascular effects. However, most studies focused on the acute effects of short-term fine particulate matter (PM2.5) exposure and the general population. Evidence from long-term cohort studies based on the cardiovascular disease (CVD) patients was scarce. Our study aimed to explore the impact of long-term exposure to PM2.5 on the mortality among post-CVD patients. This is a cohort study that involved 5143 post-CVD patients in Beijing, China. We collected records of CVD patients from hospitals in Beijing, China from 1 January 2012 to 31 December 2012 and followed up these patients from hospital admission until December 31, 2016. The vital status of the patients was determined using the National Death Surveillance Point System (DSPs). The PM2.5 concentrations were obtained from the Atmospheric Composition Analysis Group. The Cox regression models were used for data analyses. Our findings suggested that increased mortality of CVD patients with an HR of 1.43 (95% CI: 1.24, 1.63) was related to long-term exposure to PM2.5. The association was stronger for cardiovascular-related mortality, especially for mortality from myocardial infarction (MI). The HR for any CVD mortality was 1.57 (95% CI: 1.27, 1.94), HR for MI mortality was 1.82 (95% CI: 1.16, 2.83). Long-term PM2.5 exposure may significantly affect the survival of CVD patients. Compared with the general population, patients with CVD are more susceptible to PM2.5 exposure. Increased attention to the management of CVD patients is warranted.

Abstract
There are relatively few studies that focus on the health effects of exposure to size-specific particles on respiratory mortality in China. We aimed to examine the association between different particle sizes and mortality from cause-specific respiratory diseases. We used a time series model with a quasi-Poisson link to investigate the relationship between different particle sizes and mortality from respiratory diseases, chronic obstructive pulmonary diseases (COPD), pneumonia, and asthma in Shenzhen during 2014-2017. A total of 3716 mortalities due to respiratory diseases were collected. Both PM1 and PM2.5 were associated with mortality of overall respiratory diseases, COPD, and pneumonia. An interquartile range (IQR) increase in PM1 at lag03 was associated with a 12.21% (95% CI: 2.59%, 22.75%) increase in respiratory mortality, and each IQR increase in PM2.5 at lag03 corresponded to a 12.09% (95% CI: 2.52%, 22.56%) increase in respiratory mortality. PM1-2.5 was not associated with mortality from all-cause or cause-specific respiratory diseases. This study suggests that both PM1 and PM2.5 may increase the risk of mortality due to respiratory diseases in Shenzhen, China.

Abstract
We investigate the prospective association between neighbourhood-level disadvantage and cardiovascular disease (CVD) among mid-to-older aged adults and whether physical activity (PA) mediates this association. The data come from the HABITAT project, a multilevel longitudinal investigation of health and wellbeing in Brisbane. The participants were 11,035 residents of 200 neighbourhoods in 2007, with follow-up data collected in 2009, 2011, 2013 and 2016. Multilevel binomial regression was used for the cross-sectional analysis and mixed-effect parametric survival models were used for the longitudinal analysis. Models were adjusted for age, sex, education, occupation, and household income. Those with pre-existing CVD at baseline were excluded from the longitudinal analyses. The mediated effect of PA on CVD was examined using multilevel generalized structural equation modelling. There was a total of 20,064 person-year observations across the five time-points clustered at three levels. Results indicated that the incidence of CVD was significantly higher in the most disadvantaged neighbourhoods (OR 1.50; HR 1.29) compared with the least disadvantaged. Mediation analysis results revealed that 11.5% of the effect of neighbourhood disadvantage on CVD occurs indirectly through PA in the most disadvantaged neighbourhoods while the corresponding figure is 5.2% in the more advantaged areas. Key findings showed that neighbourhood disadvantage is associated with the incidence of CVD, and PA is a significant mediator of this relationship. Future research should investigate which specific social and built environment features promote or inhibit PA in disadvantaged areas as the basis for policy initiatives to address inequities in CVD.

Changes in nitrate accumulation mechanisms as PM 2.5 levels increase on the North China Plain: A perspective from the dual isotopic compositions of nitrate. CHEMOSPHERE 2021; 263:127915.

Abstract
Nitrate (NO3-) has become recognized as the most important water-soluble ion in fine particulate (PM2.5), and has been proposed as a driving factor for regional haze formation. However, nitrate formation mechanisms are still poorly understood. In this study, PM2.5 samples were collected from September 2017 to August 2018 in Shijiazhuang, a city located on the North China Plain, and NO3-concentration, δ18O-NO3- and δ15N-NO3- values in PM2.5 were analyzed. NO3- concentrations increased as PM2.5 levels increased during both polluted and non-polluted days over the entire year. δ18O-NO3- values during cold months (63.5-103‰) were higher than those during warm months (50.3-85.4‰), these results suggested that the nitrate formation pathways shifted from the NO2 + OH (POH) in warm months to the N2O5 + H2O (PN2O5) and NO3 + VOCs (PNO3) pathways in cold months. Especially during cold months, δ18O-NO3- values increased from 65.2-79.9‰ to 80.7-96.2‰ when PM2.5 increased from ∼25 to >100 μg/m3, but when PM2.5 > 100 μg/m3, there were relatively small variations in δ18O-NO3-. These results suggested that nitrate formation pathways changed from POH to PN2O5 and PNO3 pathways when PM2.5 < 100 μg/m3, but that PN2O5 and PNO3 dominated nitrate production when PM2.5 > 100 μg/m3. Higher δ15N-NO3- values in warm months (-11.8-13.8‰) than in cold months (-0.7-22.6‰) may be attributed to differences in NOx emission sources and nitrogen isotopic fractionation among NOx and NO3-. These results provide information on the dual isotopic compositions of nitrate to understand nitrate formation pathways under different PM2.5 levels.

Abstract
According to the epidemiological surveys, ambient air pollution has directly related to mortality and different diseases such as cardiovascular and respiratory defects. Among the atmospheric contaminants, criteria air ones (NO2, O3, PM2.5/10, SO2) demonstrated that have particular importance in the community disease. The overall goal of this paper was to study the impact of criteria air contaminants on the health of the inhabitants of Shiraz city, Iran. To accomplish this, the AirQ2.2.3 software was applied. The results of the study revealed that the annual average NO2, SO2, PM2.5, PM10, and O3 concentrations are 39.98, 27.6, 14.35, 46.16, and 120.03 μg/m3 in 2016 and 30.27, 23.97, 16.45, 51.65, and 52.58 μg/m3 in 2017. The total International Classification of Diseases (ICD), cardiovascular, and respiratory mortalities caused by air contaminants in Shiraz was predicted as 911, 628, and 182 cases in 2016, and 346, 370, and 82 cases in 2017, respectively. Sulfur dioxide (SO2) had the greatest rate of total mortality with the attributable equivalent of 4.3% in 2016, but this value has been decreased to 0.42% in 2017. The findings of this research revealed that air contamination has caused problems in Shiraz city according to the predicted results. The findings of this work provide useful data for regional and national health policymakers, who should take decisions to develop strategies for control air contaminants and estimate the cost-effectiveness of interventions.

Ammonia is a hazardous environmental pollutant that can be harmful to animal health. In this study, we aimed to evaluate the effect of ammonia exposure on broiler chicken spleens. We randomly divided one hundred twenty 1-day-old broiler chickens into 3 groups and raised them with exposure to different ammonia concentrations (low, middle, and high); at 42 D of age, the chicken spleens were extracted. We observed histopathologic changes in spleen tissues by microscopy and measured the expression of Th1/Th2 secreted cytokines (interleukin [IL]-1β, IL-2, IL-4, IL-6, IL-10, interferon-γ [IFN-γ], tumor necrosis factor-α) by RT-PCR. We also measured the expression of nuclear receptor-κB (NF-κB) pathway–related genes (cyclooxygenase-2 [COX-2], nitric oxide synthase [iNOS], and prostaglandin synthetase [PGE]) in spleens by RT-PCR and Western blot analysis. Histopathologic observations indicated that the spleen tissues were seriously injured in the high ammonia concentration group. There was abnormal cytokine expression, including increased IL-4, IL-6, and IFN-γ and decreased IL-2, which indicated an imbalance in the Th1/Th2 response. The proinflammatory factors such as NF-κB, COX-2, iNOS, and PGE were upregulated in the high ammonia group. In conclusion, this study illustrated that ammonia exposure led to a Th1/Th2 immune imbalance and triggered the NF-κB pathway, causing inflammatory damage to the spleen.

Abstract
BACKGROUND The associations between maternal exposure to ambient PM2.5 during pregnancy and the risk of premature rupture of membranes (PROM) and preterm premature rupture of membranes (PPROM) are controversial. And no relevant study has been conducted in Asia. This study aimed to determine the association between maternal exposure to ambient PM2.5 during pregnancy and the risk of (P)PROM. METHODS A cohort study including all singleton births in a hospital located in Central China from January 2015 through December 2017 was conducted. Multivariable logistic regression models, stratified analysis, generalized additive model, and two-piece-wise linear regression were conducted to evaluate how exposure to ambient PM2.5 during pregnancy is associated with the risks of PROM and PPROM. RESULTS A total of 4364 participants were included in the final analysis, where 11.71 and 2.34% of births were complicated by PROM and PPROM, respectively. The level of PM2.5 exhibited a degree of seasonal variation, and its median concentrations were 63.7, 59.3, 55.8, and 61.8 μg/m3 for the first trimester, second trimester, third trimester, and the whole duration of pregnancy, respectively. After adjustment for potential confounders, PROM was positively associated with PM2.5 exposure (per 10 μg/m3) [Odds Ratio (OR) = 1.14, 95% Confidence Interval (CI), 1.02-1.26 for the first trimester; OR = 1.09, 95% CI, 1.00-1.18 for the second trimester; OR = 1.13, 95% CI, 1.03-1.24 for the third trimester; OR = 1.35, 95% CI, 1.12-1.63 for the whole pregnancy]. PPROM had positive relationship with PM2.5 exposure (per 10 μg/m3) (OR = 1.17, 95% CI, 0.94-1.45 for first trimester; OR = 1.11, 95% CI, 0.92-1.33 for second trimester; OR = 1.19, 95% CI, 0.99-1.44 for third trimester; OR = 1.53, 95% CI, 1.03-2.27 for the whole pregnancy) Positive trends between the acute exposure window (mean concentration of PM2.5 in the last week and day of pregnancy) and risks of PROM and PPROM were also observed. CONCLUSIONS Exposure to ambient PM2.5 during pregnancy was associated with the risk of PROM and PPROM.

Abstract
The aim of the study was to evaluate the health effects associated with the exposure to ground-level of particulate matters with aerodynamic diameter ≤ 2.5 μm (PM2.5) on citizens in Rome (Italy) in 2015 and 2016. Based on the new version of the World Health Organization's AirQ+ model, we have estimated the short- and long-term effects of PM2.5 on hospital admissions due to cardiovascular (HA-CVD) and respiratory diseases (HA-RD) as well as on mortality for ischemic heart disease (M-IHD) and chronic obstructive pulmonary disease (M-COPD). In this study, city-specific relative risk values and baseline incidence rates were used to calculate the association between PM2.5 and daily counts of emergency hospitalizations and mortality. The annual mean PM2.5 concentrations were 18 μg m-3 and 14 μg m-3 in 2015 and 2016, respectively. In Rome, the citizens are mostly exposed to daily mean PM2.5 concentrations of 10-20 μg m-3 during the study period. In 2015-2016, 0.4-0.6% for HA-CVD, 1.1-1.5% for HA-RD, 16.5-18.1% for M-IHD and 8.5-9.2% for M-COPD are attributed to PM2.5. In 2015-2016, 134-186 HA-CVD, 126-175 HA-RD, 947-1037 M-IHD and 244-279 M-COPD, caused by PM2.5 exposure, could be "avoided" if PM2.5 concentrations would not exceed 10 μg m-3, i.e. the threshold recommended by the World Health Organization. Thus, a consistent air quality management and sustainable city planning are needed, urgently, to mitigate the adverse effects of PM2.5 exposure in Rome.

Abstract
H2S is one of the air pollutants, which can cause multiple organ damage to the body. H2S exposure will directly damage respiratory system and cause inflammatory reaction. In this experiment, the effect of H2S on LPS-induce chicken pneumonia is explored from the Th1/Th2 balance and the NF-κB pathway. 42-day-old broilers was selected as research object, exposed to exogenous H2S, received an intraperitoneal injection of LPS to establish inflammatory model on forty-second days. We carry out qRT-PCR and Western blot to detect the expression of cytokines secreted by Th1/Th2, PPAR-γ/HO-1 genes, NF-κB pathway genes and the downstream genes COX-2 and iNOS. We found the expression of IL-4, IL-6, TNF-α and IL-1β increased and that of IFN-γ decreased, which indicating the immune imbalance of Th1/Th2 was occurred and the level of PPAR-γ/HO-1 was significantly suppressed. In addition, the activation of I-κB-β and NF-κB genes with the degradation of I-κB-α indicated that NF-κB pathway has been activated, which accompanied with COX-2, PGE and iNOS increasing. These results suggested that H2S exposure can lead to Th1/Th2 immune imbalance, repress the anti-inflammatory effect of PPAR-γ/HO-1, and then activate NF-κB pathway-related genes and the downstream genes to aggravate pneumonia induced by LPS.

Abstract
Chemical speciation of fine particles or PM2.5 collected on filters is still a costly and time-consuming task. In this study, filter-based PM2.5 samples were collected during November-December 2013 at four sites in Guangzhou, and the major components were fast screened (~7min per filter sample) by Attenuated Total Reflectance (ATR)-Fourier Transform Infrared Spectroscopic (FTIR) in comparison with that measured by Organic carbon/Element carbon (OC/EC) analyzer and Ion Chromatography (IC). The concentrations of nitrate, ammonium, sulfate, primary organic carbon (POC) and secondary organic carbon (SOC) measured by OC/EC and IC analyzers were better correlated with their infrared absorption peak heights at 1320cm-1 for nitrate, 1435, 3045 and 3215cm-1 for ammonium, 615cm-1 for sulfate, 690, 760 and 890cm-1 for POC and 1640 and 1660cm-1 for SOC respectively, during polluted days (PM2.5>75μg/m3) than during clean days (PM2.5≤75μg/m3). With the evolution of a haze episode during our field campaign, the concentrations of the major PM2.5 components displayed consistent variations with their infrared absorption peak heights, suggesting ATR-FTIR could be a fast and useful technique to characterize filter-based PM2.5 compositions particularly during pollution events although cautions should be taken when PM2.5 levels are low. Notably, elevated PM2.5 mass concentrations occurred with enhanced ratios of [NO3-]/[SO42-] and [NH4+]/[SO42-], implying that nitrogenous components play vital roles in the PM2.5 pollution events in the study region.

Abstract
Amongst the various pollutants in the air, particulate matters (PM) have significant adverse effects on human health. The current research is based on existing epidemiological literature for quantitative estimation of the current health impacts related to particulate matters in some selected principal Iranian megacities. In order to find the influence of air pollution on human health, we used the AirQ software tool presented by the World Health Organization (WHO) European Centre for Environment and Health (ECEH), Bilthoven Division. The adverse health outcomes used in the study consist of mortality (all causes excluding accidental causes), due to cardiovascular (CVD) and respiratory (RES) diseases, and morbidity (hospital admissions for CVD and RES causes). For this purpose, hourly PM10 data were taken from the monitoring stations in eight study cities during 2011 and 2012. Results showed annual average concentrations of PM10 and PM2.5 in all megacities exceeded national and international air quality standards and even reached levels nearly ten times higher than WHO guidelines in some cities. Considering the short-term effects, PM2.5 had the maximum effects on the health of the 19,048,000 residents of the eight Iranian cities, causing total mortality of 5,670 out of 87,907 during a one-year time-period. Hence, reducing concentrations and controlling air pollution, particularly the presence of particles, is urgent in these metropolises.

Abstract
BACKGROUND Sources of air pollutants are significant factors for adverse health effect. Few current studies explored the linking of sources influence and ambient pollutants to asthma patient visits in Shanghai, China. OBJECTIVES This study explored the associations between short-term exposures to ambient pollutants and asthma morbidity with terrestrial and marine source influence in Shanghai. METHODS Generalized additive model (GAM) was used to explore the association of daily patient visits and ambient pollutants. These analyses were calculated in R statistical software in mgcv package. PSCF modeling was used to locate potential source areas contributing to the concentrations of pollutants. RESULTS We found that per IQR of PM2.5, PM10, NO2, SO2, O3 and CO in terrestrial source were associated with an increase of 6.63% (95% CI: -0.27% to 14%), 6.48% (95% CI: 0.06% to 13.3%), 1.68% (95% CI: -2.68% to 6.24%), 2.81% (95% CI: -1.42% to 7.22%), -0.60% (95% CI: -5.94% to 5.04%) and 16.6% (95% CI: 8.68% to 25.2%), respectively in asthma patient visits. Per IQR of PM2.5, PM10, NO2, SO2, O3 and CO in marine source were associated with an increase of 5.34% (95% CI: 0.42% to 10.5%), 3.84% (95% CI: 0.08% to 7.74%), 3.21% (95% CI: -0.92% to 7.52%), 2.58% (95% CI: -1.02% to 6.30%), 1.42% (95% CI: -3.10% to 6.15%) and 8.81% (95% CI: 2.56% to 15.4%). The PSCF show all of the pollutants except O3 mainly come from terrestrial during observation. We also found that all of the pollutants except NO2 displayed the highest effect in the spring for relative risk of asthma morbidity. CONCLUSIONS Ambient air pollutants that cause an increase in asthma patient visits, such as PM2.5, PM10, NO2, SO2 and CO are mainly produced from terrestrial sources, while O3 is primarily from marine sources. The association of ambient pollutants and asthma patient visits is closely related with seasons, especially with spring. PM2.5 and CO are major air pollutants increasing the relative risk of asthma patient visits in Shanghai.

Abstract
OBJECTIVE Risk factors for suicide can be broadly categorized as sociodemographic, clinical and treatment. There is interest in environmental risk and protection factors for suicide. Emerging evidence suggests a link between environmental factors in the form of air pollution and aeroallergens in relation to suicidality. METHODS Herein, we conducted a systematic review of 15 articles which have met inclusion criteria on the aforementioned effects. RESULTS The majority of the reviewed articles reported an increased suicide risk alongside increased air pollutants or aeroallergens (i.e. pollen) increase; however, not all environmental factors were explored equally. In specific, studies that were delimited to evaluating particulate matter (PM) reported a consistent association with suicidality. We also provide a brief description of putative mechanisms (e.g. inflammation and neurotransmitter dysregulation) that may mediate the association between air pollution, aeroallergens and suicidality. CONCLUSION Available evidence suggests that exposure to harmful air quality may be associated with suicidality. There are significant public health implications which are amplified in regions and countries with greater levels of air pollution and aeroallergens. In addition, those with atopic sensitivity may represent a specific subgroup that is at risk.

Abstract
Particulate matter with an aerodynamic diameter less than 2.5μM (PM2.5) is one of the major environmental pollutants in China. In this study, we carried out a metabolomics profile study on PM2.5-induced inflammation. PM2.5 from Beijing, China, was collected and given to rats through intra-tracheal instillation in vivo. Acute pulmonary injury were observed by pulmonary function assessment and H.E. staining. The lipid metabolic profile was also altered with increased phospholipid and sphingolipid metabolites in broncho-alveolar lavage fluid (BALF) after PM2.5 instillation. Organic component analysis revealed that benzo[a]pyrene (BaP) is one of the most abundant and toxic components in the PM2.5 collected on the fiber filter. In vitro, BaP was used to treat A549 cells, an alveolar type II cell line. BaP (4μM, 24h) induced inflammation in the cells. Metabolomics analysis revealed that BaP (4μM, 6h) treatment altered the cellular lipid metabolic profile with increased phospholipid metabolites and reduced sphingolipid metabolites and free fatty acids (FFAs). The proportion of ω-3 polyunsaturated fatty acid (PUFA) was also decreased. Mechanically, BaP (4μM) increased the phospholipase A2 (PLA2) activity at 4h as well as the mRNA level of Pla2g2a at 12h. The pro-inflammatory effect of BaP was reversed by the cytosolic PLA2 (cPLA2) inhibitor and chelator of intracellular Ca2+. This study revealed that BaP, as a component of PM2.5, induces pulmonary injury by activating PLA2 and elevating lysophosphatidylcholine (LPC) in a Ca2+-dependent manner in the alveolar type II cells.

Abstract
BACKGROUND The aim of this study was to investigate the cardiotoxicity and mechanism of particulate matter 2.5 (PM2.5) exposure on offspring rats during pregnancy. MATERIAL AND METHODS Wistar rats were used to establish a PM2.5 exposure animal model during pregnancy, and they were divided into a control group, a low-dose group, a middle-dose group, and a high-dose group according to PM2.5 exposure dose. The pathological changes of heart tissue, the rate of myocardial cell apoptosis, the levels of LDH, AST, and CM-KB in serum, and the difference in mitochondrial fusion genes (OPA1 and Mfn1) and mitochondrial genes (Drp1 and Fis1) were compared among groups. RESULTS The arrangement of myocardial fibers in offspring mice of PM2.5 exposure groups became disordered, the shape of some cardiomyocytes became irregular, and some staining darker nuclei appeared. The apoptotic rates of myocardium in offspring rats exposed to PM2.5 were (12.61±0.93)% in the low-dose group, (25.14±1.53)% in the middle-dose group, and (30.13±1.50)% in the high-dose group, which were all significantly higher than in the control group (9.12±0.80)% (P<0.05). The levels of LDH, AST, and CM-KB and the expression of OPA1, Mfn1, Drp1, and Fis1 in offspring mice of PM2.5 exposure groups increased with the increase of PM2.5 exposure dose, and were significantly higher than that of the control group (P<0.05). CONCLUSIONS The mitochondria of the offspring mice were damaged due to the abnormal expression of mitochondrial fusion/splicing gene by PM2.5 exposure during pregnancy, and the hearts of offspring mice were damaged due to damaged mitochondria.
