Abstract The formation mechanism of aerosol sulfate during wintertime haze events in China is still largely unknown. As companions, SO 2 and transition metals are mainly emitted from coal combustion. Here, we argue that the metal-catalyzed oxidation on surfaces could be dominant pathway investigate this hypothesis by integrating chamber experiments, numerical simulations in-field observations. Our analysis shows contribution manganese-catalyzed approximately one to two orders magnitude...
Abstract. China's new "Twelfth Five-Year Plan" set a target for total NOx emission reduction of 10% the period 2011–2015. Heavy-duty diesel vehicles (HDDVs) have been considered major contributor to emissions in China. Beijing initiated comprehensive vehicle test program 2008. This included sub-task measuring on-road profiles hundreds HDDVs using portable measurement systems (PEMS). The finding is that neither distance-specific (g km−1) nor brake-specific kWh−1) factors buses and heavy-duty...
Abstract. Humic-like substances (HULIS) are a mixture of high-molecular-weight, water-soluble organic compounds that widely distributed in atmospheric aerosol. Their sources rarely studied quantitatively. Biomass burning is generally accepted as major primary source ambient humic-like with additional secondary material formed the atmosphere. However, present study provides direct evidence residential coal also significant HULIS, especially heating season northern China based on measurements,...
There is a large gap between the simulated and observed sulfate concentrations during winter haze events in North China. Although multiphase formation mechanisms have been proposed, they not evaluated using chemical transport models. In this study, Weather Research Forecasting model coupled with Chemistry (WRF-Chem) was used to apportion formation. It found that Mn-catalyzed oxidation on aerosol surfaces dominant pathway, accounting for 92.3 ± 3.5% of events. Gas-phase contributed 3.1 0.5%...
Field measurements in rural households were conducted three Chinese municipalities/provinces (Beijing, Chongqing, and Henan) to determine the emission characteristics of particulate matter from biofuel combustion. The selected types stove are representative local areas. Particle number concentration, size distribution, mass distribution determined. Both particle these emissions dominated by submicrometer particles. factor PM2.5 combustion is between 1.80 7.00 g/kg (dry basis) 0.84−2.40 g/MJ...
Particulate polycyclic aromatic hydrocarbons (p-PAHs) emitted from diesel vehicles are of concern because their significant health impacts. Laboratory tests, road tunnel and roadside experiments have been conducted to measure p-PAH emissions. While providing valuable information, these methods limited capabilities characterizing emissions either individual or under real-world conditions. We employed a portable measurement (PEMS) emission factors priority p-PAHs for representative an array...
Ambient and household air pollution are found to lead premature deaths from all-cause or cause-specific death. The national lockdown measures in China during COVID-19 were abrupt changes ambient surface quality, but indoor quality neglected. In this study, we aim investigate the impacts of on both as well short-term health effects changes. an up-to-date emission inventory January March 2020 was developed based observations combination with emission-concentration response functions derived...
