摘要
以乌鲁木齐市和上海市中心城区为研究区域,按不同功能区对城市土壤采样并进行Pb含量及形态分析,结果表明:两市土壤Pb的平均值含量均超出相应土壤Pb的背景值,上海市土壤Pb的含量远远高于乌鲁木齐市;两市土壤Pb在各功能区的分布均存在明显差异,但两市土壤Pb在功能区的分布规律并不相同;两市土壤Pb的形态分布规律趋于一致,乌鲁木齐市土壤Pb活性要大于上海市。造成上述城市土壤Pb污染特征的影响因素有很多。
The concentration and chemical speciation of lead in urban soil of Untmqi city and Shanghai city were studied. The results indicated that both cities had high contents of Pb, The content of Pb soil in Shanghai had higher than in Urumqi. There were some sifferent polluted levels of Pb in different dements of certain city, and two cities had different character; species of Pb in two cities had the same distribution pattern, but activities of Pb in Urumqi were higher than in Shanghai. These polluted character were caused by many Influence factors.
