摘要
2011年江苏省环境监测中心对南京市鼓楼、建邺、栖霞3区8个采样点采集了TSP和PM10样品,进行颗粒物质量浓度、水溶性离子、无机元素以及碳成分分析。结果表明该市春季大气颗粒物污染以PM10为主,不同区域颗粒物污染特点不一;水溶性离子以Ca2+、NO3-及SO2-4居多;无机元素以Ca、Fe、Al为主,Pb与Zn浓度较Ni与V高;市内EC浓度较高,可能与裸露堆煤场有关。有关研究结果提交南京市政府部门,供决策时参考。
TSP and PMi0 samples of 8 points have been acquired in Gulou, Jianye and Qixia District of Nanjing city in 2011 by Jiangsu Environmental Monitoring Center, the particles density quality, water soluble ions, inorganic elements, as weU as carbon in gredient were analyzed. Results indicate that PM10 is the main pollutant in city＇s spring atmosphere, pollution Characteristics is dif- ferent for different region; Ca2 ＋ , NO3 - and SO2 - contributed most in water-soluble ions ; inorganic elements mainly include Ca, Fe, A1, and the density of Pb and Zn is higher than that of Ni and V; city＇s high concentration of EC may be related to the exposed coal yard. The findings of the study were submitted to Nanjing Municipal Departments for further decision-making.
