Abstract The combustion of solid fuels, including coal and biomass, is a main anthropogenic source atmospheric particulate matter (PM). hidden costs have been underestimated due to lack consideration the toxicity PM. Here we report unequal inhalable PM emitted from energy use in residential sector coal-fired power plants (CFPPs). incomplete burning fuels household stoves generates much higher concentrations carbonaceous matter, resulting more than one order magnitude greater that CFPPs. When compared with CFPPs, consumed only tenth mainland China 2017, but it contributed about 200-fold population-weighted toxic potency-adjusted 2.5 exposure risk. We suggest -related should be considered when making air pollution emission control strategies, sources receive policy attention reduce risks.

Air-borne pollutants in particulate matter (PM) form, produced either physically during industrial processes or certain biological routes, have posed a great threat to human health. Particularly the current COVID-19 pandemic, effective filtration of virus is an urgent worldwide. In this review, we first introduce some fundamentals about PM, including its source and classification, mechanisms, evaluation parameters. Advanced materials their functions are then summarized, among which polymers MOFs discussed detail together with antibacterial performance. The discussion on application divided into end-of-pipe treatment control. Finally, conclude review our prospective view future research area.

Protecting human health from fine particulate matter (PM) pollution is the ambitious goal of clean air actions, but current control strategies largely ignore role source-specific PM toxicity. Here, we proposed health-oriented by integrating unequal toxic potencies most polluting industrial PMs. Iron and steel industry (ISI)-emitted PM2.5 exhibit about one order magnitude higher potency than those cement power industries. Compared with mass-based strategy (prioritizing implementation ultralow emission standards in sector), (priority ISI sector) could generate 5.4 times reduction population-weighted potency-adjusted exposure among industries China. Furthermore, marginal abatement cost per unit mass ISI-emitted only a quarter that other two sectors under scenarios. We highlight urgently required to achieve cost-effective reductions risks.

Organic compounds are important contributors to the oxidative potential (OP) of atmospheric aerosols. This study is first report OP water-soluble organic matter (WSOM) related chromophoric substances in PM2.5 over Xi'an, China. The dithiothreitol (DTT) activity levels extracted by water were quantified as well relationships between DTT and light absorption fluorescence properties. results show that has significantly correlated with colored WSOM, which we identified three absorbing (BrC1-3) eight fluorescent (C1-8). It further found BrC3 C7 accounted for almost all although these two factors contributed only a small fraction fluorescence. clearly distinguished from other because their long wavelength (λmax = 475 nm) emission 462 nm), respectively. discovery will help better interpret understand mechanism oxidation generation aerosols provide guidance predicting OPs based on optical

Reactive oxygen species (ROS) are a class of substances that general concern in terms human health and used to represent the oxidation potential (OP) atmosphere. In this study, ROS levels 116 daily fine particulate matter (PM2.5) samples taken over Xi'an 2017 were measured with dithiothreitol (DTT) method. The sources DTTv (volume-based DTT consumption) PM2.5 as well their contributions identified by both positive matrix factorization (PMF) multiple linear regression (MLR) based on chemical (PM). results showed yearly average was 0.53 nmol/min/m3 (0.19-1.10 nmol/min/m3). highest level occurred winter, followed spring, summer autumn. most strongly correlated water-soluble organic carbon (WSOC; r = 0.85), but effects WSOC very limited. SO2, NO2, CO, elemental (EC) K+ (r > 0.64) had moderate correlations moderately related environmentally persistent free radicals (EPFRs) 0.56). mixed-effects model pollutants originating from incomplete combustion greater than those complete combustion. Source apportionment PMF motor vehicle emissions (27.4%), secondary sulfates (21.6%) coal (18.8%) more important contributors dust (8.4%), metal processing (4.9%), industrial (11.3%) nitrates (7.5%). for consistent MLR results, which verified feasible methods source specific such EPFRs. Backward trajectory clusters dominant cluster groups local regional transport, while OP affected long-range transport transport. As stated above, improvement atmospheric require not only efforts also large-scale joint cooperation. Furthermore, study PM information provides guidance effect research.

EEnvironmental pollutants and allergens induce oxidative stress mitochondrial dysfunction, leading to key features of allergic asthma. Dysregulations in autophagy, mitophagy, cellular senescence have been associated with environmental pollutant allergen-induced stress, secretion multiple inflammatory proteins, subsequently development Particularly, particulate matter 2.5 (PM2.5) has reported autophagy the bronchial epithelial cells through activation AMP-activated protein kinase (AMPK), drive mitophagy activating PTEN-induced 1(PINK1)/Parkin pathway, cell cycle arrest senescence. Intriguingly, allergens, including ovalbumin (OVA), alternaria alternata, cockroach allergen, also shown different signaling pathways. Additionally, dysfunction can due excessive ROS production, which affects airway diseases. Although share similar properties, recent studies suggest that either accelerate or prevent Thus, this review, we evaluated literature regarding basic processes, senescence, explored their molecular mechanisms regulation initiation downstream signaling. Especially, highlighted involvement pollutant/allergen-induced major phenotypic changes asthma such as inflammation remodelling reviewed novel critical research areas for future studies. Ultimately, understanding regulatory may allow new therapeutic targets
