目的 探讨重金属镉(Cd)与人体内金属硫蛋白(MTs)的关系及相互影响. 方法用茜素红共振光散射法和石墨炉原子吸收分光光度法分别测定不同环境人群尿中Cd和MTs的含量. 结果职业暴露人群组与对照组尿中Cd和MTs差异均有统计学意义(P＜0.001),并且尿Cd与尿MTs呈直线相关关系(r=0.585,P＜0.001). 结论尿中MTs的含量可以反映人体镉中毒的程度,并且在重金属污染环境风险评价中具有重要意义.

Objective To investigate the changes of MTs in vivo effected by cadmium. Methods We determined the content of urinary MTs and cadmium in different crowds by RLS method using alizarin red and graphite furnace atomic absorption spetrophotometry （GFAAS） respectively. Results The results showed that.statistical significant differences existed in the different crowds （P〈0. 001）, moreover, there was a linear correlation between cadmium and MTs （r = 0..585, P〈 0. 001）. Conclusions The urinary MTs can reflect the degree of cadmium toxicity and it is of great value in asses...
