摘要
以徐州市北郊工业区作为研究对象,探讨工业型城市大气总悬浮颗粒物中重金属元素的时空分布特征。监测结果表明,该区大气TSP中重金属污染较为严重,单个样品中重金属铅、锌、镉、铬、铜和锰的最高含量分别达350.9、1037.9、5.5、16.3、17.8、238.5mg/kg;元素浓度呈秋冬季偏高,夏秋季偏低的趋势;空间分布充分体现了与污染源地域分布的一致性。
The north suburb of Xuzhou was selected as research area. The TSP was series monitored and the concentration of Cu, Cd, Pb, Cr , Zn and Mn in TSP were analyzed. The results indicated that TSP was polluted by heavy metals seriously. The maximum concentration of Cu,Cd,Pb, Cr ,Zn and Mn in TSP respectively are： 350.9, 1037.9, 5.5, 16.3, 17.8 and 238.5 mg/kg. And the concentration of heavy metals was higher in spring ＆ winter and lower in summer ＆ autumn. The spatial distribution was identical with the space distribution of the pollution sources.
