目的：探讨沙颍河污染区外环境重金属暴露对居民血清铅、镉、锌、铜及金属硫蛋白（ MT ）的影响。方法：在距沙颍河河堤5 km以内和20 km以外各选取一个人口构成相似的村庄分别作为污染区和对照区，测量河水、饮用水、土壤、蔬菜和粮食中的铅、镉含量。采用火焰原子吸收光谱法测定河水、饮用水、土壤、蔬菜、粮食中的铅、镉含量；采用溶出伏安法测定各组人群血清中的铅、镉、锌、铜含量；采用ELISA方法测定人群血清中MT的含量。结果：污染区饮用水、土壤、粮食和蔬菜中的铅、镉含量均高于对照区（铅：t＝2．663、2．300、3．001和2．117，P＜0．05；镉：t＝3．549、2．073、2．202和2．167，P＜0．05）；污染区人群的血清铅、镉水平和铜/锌比值高于对照区（t＝5．544、10．438和5．556，P＜0．05）；血清MT含量随着血清铅、镉含量的增加而增加。结论：沙颍河水污染已影响到当地居民体内的重金属负荷。

chosen from villages less than 5 km and more than 20 km away from the Shaying River respectively , which had similar pop-ulation composition and economy condition .The concentrations of lead and cadmium in drinking water , soil, grain and veg-etables samples from the two areas were measured respectively by flame atomic absorption spectrometry .Serum lead , cad-mium, zinc and copper levels were determined by cyclic voltammetry method .Serum MT level was measured by ELISA . Results:The levels of serum lead , cadmium in drinking water , soil, grain and vegetable samples in the contaminated area were significantly higher than those of control area ( lead:t =2.663,2.300,3.001,and 2.117,P<0.05;cadmium:t =3.549,2.073,2.202,and 2.167,P<0.05).The levels of serum lead, cadmium, zinc, and Cu/Zn in the contaminated area were significantly higher than those of control area respectively (t=5.544,10.438,and 5.556,P<0.05).Conclu-sion:Water pollution of Shaying River has affected the load of heavy metals in local residents .
