In this study, PM2.5 samples had been measured from the summer of 2009 to the winter of 2010 in a suburb of Shenzhen. The results indicated serious PM2.5 pollution in the suburb of Shenzhen. Seasonal and daily variations of water-soluble ions were discussed. SO4(2-), NO3(-) and NH4+ were the most abundant ions in winter. In summer, the average contributions of Cl(-), Na+, K+, Ca2+ and Mg2+ increased significantly, while SO4(2-), NO3(-) and NH4+ decreased. Furthermore, Naphthalene… CONTINUE READING
