Abstract Nitrate (NO 3 − ), one of the most important inorganic aerosols in atmosphere, is mainly formed by oxidation NO x hydroxyl radical (OH) and ozone (O ) urban atmospheres. However, fractional contributions its various pathways remain unclear. Here, we collected particulate matter with aerodynamic diameter less than 2.5 μm (PM samples a second‐tier city southeast China from 1 September to 31 December 2017 measured nitrate isotopic compositions (δ 15 N δ 18 O). The average concentration...
Chlorine is an important atmospheric photochemical oxidant, but few studies have focused on chlorine. In this study, PM2.5 samples were collected from urban and rural sites across China in January 2018, concentrations of Cl− other water-soluble ions analyzed. The size-segregated aerosol data measured Chinese cities by compiled for comparison. observed demonstrated that the northern (5.0 ± 3.7 µg/m3) higher than those central (1.9 1.2 southern (0.84 0.54 µg/m3), suggesting substantial...
In this study, we measured the daily water-soluble inorganic ions (WSIIs) concentration (including SO42−, NO3−, NH4+, Ca2+, K+, Cl−, Na+, Mg2+, and F−) of PM2.5 (particulate matter with a diameter smaller than 2.5 μm) throughout year in Nanning (a typical subtropical monsoon climate city southwestern China) to explore influence seasonal change on properties pollution. This suggested that NH4+ were main component WSIIs Nanning. Secondary from fossil fuel combustion, agricultural activities,...
Sulfate, nitrate and ammonium (SNA) are the dominant components of water-soluble ions (WSIs) in PM2.5, which great significance for understanding sources transformation mechanisms PM2.5. In this study, daily PM2.5 samples were collected from September 2017 to August 2018 within Guiyang urban area concentrations major WSIs characterized. The results showed that average concentration SNA (SO42−, NO3−, NH4+) was 15.01 ± 9.35 μg m−3, accounting 81.05% (48.71–93.76%) total 45.33% (14.25–82.43%)...
As the primary component of air pollution, nitrogen oxides (NOx = NO + NO2) are responsible for formation ozone and fine particle matter (PM2.5), which together pose a threat to environment human health worldwide. Coal combustion is assumed be prominent emitter atmospheric NOx in urban environments on basis isotopic constraints (δ15N), but recently detailed emission inventories inconsistent with extant estimates. To resolve this disagreement, we compiled dissected previously reported δ15N...
