摘　　要：本项研究通过单点采样,对西安东二环附近总悬浮颗粒物(TSP)污染状况及TSP中重金属的浓度变化趋势和组配特征进行研究。结果显示,观测点处2006年冬季与2007年春季的TSP日均浓度的平均值均超过国家空气环境质量二级标准(0.30mg/m3)。2006年冬季TSP中Cu、Pb、Cd、Zn、Ni的平均含量均高于2007年春季。此外,应用相关性计算,推测TSP中Pb、Cd、Cu可能具有同源性;而根据Cu、Ni高度相关,推测Cu还有另一贡献源,而Zn则来自于独立的污染源。Through sampling at a single point, study the pollution of TSP, the seasonal changes in concentration and characteristics of the group assignment of heavy metals contained in TSP near the Second Ring of East Xi＇ an. The results showed that at observation point, both in winter 2006 and spring 2007, the daily average concentration of TSP exceeded the national standards Ⅱ （0. 30 mg/m^3 ） for environmental air quality. In winter 2006, the average levels of Cu, Pb, Cd, Zn contained in TSP were higher than those in spring 2007. In addition, through the calculate of the interrelation, inferred that Pb, Cd, Cu in TSP probably have the same source. And because Cu and Ni are in highly relevant, so there is another source contribution to Cu. In addition, Zn is from independent source.
