Analysis of Chemical Composition and Sources of PM₁₀ in the Southern Gateway of Beijing by Yu Qu, Juan Yang, Xingang Liu, Yong Chen, Haiyan Ran, Junling An, Fanyeqi Yang

“…The results showed that five trace elements (Mn, Cu, As, Zn and Pb) had high enrichment in PM₁₀ and were closely related with anthropogenic combustion and vehicle emissions; organic and element carbon had a high correlation due to the same primary sources and similar evolution; nitrate dominated SNA (sulfate, nitrate, ammonium) and nitrate/sulfate ratios reached 2.35 on the polluted days owing to the significant contribution of motor vehicle emissions. …”
