| 摘要: |
| 分析并探讨了南京市秸秆焚烧期间细颗粒中水溶性阴离子和铵，有机碳(OC)和元素碳(EC)，以及Cu、Zn、Pb、Si等38种元素的含量和浓度。结果表明：细颗粒水溶性离子中硫酸根浓度最高，其次是铵根离子，硝酸盐和氯离子，氟离子和亚硝酸盐最低。秸秆焚烧期间细颗粒（PM2.5）样品中离子含量占26%，Si元素和金属所占份额为17.1%，碳元素占19.6%，其余未知的质量约占37%。 |

| 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. |
