Abstract:Analyses the concentration of water-soluble anion and ammonia, organic carbon (OC) and elemental carbon (EC), as well as copper, zinc, lead, silica and other elements (38 in total), in fine particles, during the period when stalks are burnt in Nanjing. The result shows that the water-soluble ion has highest concentration of sulfate, followed by ammonia, nitrate or chloride ion, and fluoride ion and nitrite, Ion takes 26% of fine particles (PM2.5) during that period, while silica and metals take only 17.1% and carbon takes 19.6%, with 37% unknown in the remaining.
Keywords:stalks  fine particles  components
