Emission quantification of primary particulate matter (PM) is essential for assessment its related climate and health impacts. To reduce uncertainty associated with global emissions PM2.5, PM10, TSP, we compiled data high spatial (0.1° × 0.1°) sectorial (77 sources) resolutions 2007 based on a newly released fuel product (PKU-FUEL-2007) an emission factor database. Our estimates developing countries are higher than those previously reported. Spatial bias large could be reduced by using...

Residential wood combustion is one of the important sources air pollution in developing countries. Among pollutants emitted, parent polycyclic aromatic hydrocarbons (pPAHs) and their derivatives, including nitrated oxygenated PAHs (nPAHs oPAHs), are concern because mutagenic carcinogenic effects. In order to evaluate impacts on regional quality human health, emission inventories, based realistic factors (EFs), needed. this study, EFs 28 pPAHs (EFPAH28), 9 nPAHs (EFPAHn9), 4 oPAHs (EFPAHo4)...

The health impacts of polycyclic aromatic hydrocarbons (PAHs), the most concerning organic pollutants, depend not only on locations and strengths emission sources, but also individual susceptibility. Moreover, trans-boundary transport makes them a global concern. In this study, comprehensive analysis (PAHs) in ambient air is presented. Model resolution critical exposure modelling. Globally, incremental lifetime lung cancer risk (ILCR) induced by PAH 3.1 × 10−5. If susceptibility was taken...

Emission characterization of polycyclic aromatic hydrocarbons (PAHs) from residential combustion crop residues, woody material, coal, and biomass pellets in domestic stoves rural China are compared term emission factors (EFs), influencing factors, composition profiles, isomer ratios phase distributions. The EFs PAHs vary by 2 orders magnitude among fuel types suggesting that a detailed categorization is useful the development an inventory potential abatement replacing dirty fuels with...

Agricultural droughts can create serious threats to food security. Tools for dynamic prediction of drought impacts on yields over large geographical regions provide valuable information management. Based the DeNitrification-DeComposition (DNDC) model, current research proposes a Drought Risk Analysis System (DRAS) that allows scenario-based analysis drought-induced yield losses. We assess corn using two case studies, 2012 U.S.A. and 2000 2009 in Liaoning Province, China. The results show...

Abstract This paper reports a room temperature visible‐light‐driven protocol for the intermolecular [2+2] cycloadditions between coumarin‐3‐carboxylates and acrylamides analogs by an energy‐transfer process. Using iridium complex FIrPic as photosensitizer 3 W blue LED light source, array of cyclobutabenzocypyranones were prepared in moderate to excellent yields.

Coronary heart disease (CHD), the leading cause of death globally, might be developed or exacerbated by air pollution, resulting high burden to patients. To date, limited studies have estimated relations between short-term exposure pollution and CHD in China, with inconsistent results. Hence, we aimed estimate impact ambient PM pollutants on hospitalizations specific CHD.PM10 PM2.5 were measured at 82 monitoring stations 9 cities Sichuan Province, China during 2017-2018. Based...

The spatially resolved emission inventory is essential for understanding the fate of mercury. Previous global mercury inventories fuel combustion sources overlooked influence trading on local estimates many countries, mostly developing which national data are not available. This study demonstrates that in content coal and petroleum locally consumed differ significantly from those produced. If produced fuels were used to estimate emission, then resulting emissions would be overestimated by...
