为了解某铅锌矿冶炼厂镉污染对附近村民健康影响,于2000年5月以该厂附近村庄所有在册常住居民作为暴露组(n=98),另选距冶炼厂约4 km的另一村庄村民为对照组(n=98),检测尿镉、尿β2微球蛋白。结果显示暴露组尿镉含量中位数(3.9μg/g cr)明显高于对照组(2.1μg/g cr()P<0.01);暴露组女性尿镉含量中位数(5.1μg/g cr)明显高于男性(2.9μg/g cr()P<0.05);尿镉、尿β2微球蛋白含量均有随着年龄和居住年限的增加而明显增加(P<0.05,P<0.01)的趋势。暴露组尿镉≥5μg/g cr有47人,尿镉≥15μg/g cr有21人,尿β2微球蛋白>1 000μg/g cr有4人,提示铅锌矿冶炼厂镉污染对附近村民健康已经产生了影响。
To understand the health effects of cadmium contamination in a lead-zinc mine smelter on nearby villagers, all registered permanent residents of the village near the plant were used as the exposure group (n = 98) in May 2000 and another about 4 km from the smelter Villagers in the control group (n = 98), urinary cadmium and urine β2 microglobulin. The results showed that the median urinary cadmium concentration (3.9 μg / g cr) in the exposed group was significantly higher than that in the control group (2.1 μg / g cr (P <0.01) ) Was significantly higher than that of males (2.9μg / g cr (P <0.05)). The contents of urinary cadmium and urinary β2 microglobulin increased significantly with the increase of age and residence time (P <0.05, P <0.01) trend. There were 47 urinary cadmium≥5μg / g cr in the exposed group, 21 urinary cadmium ≥15μg / g cr, and 4 urinary β2 microglobulin> 1000μg / g cr, suggesting that the cadmium pollution in the lead-zinc mine smelter is harmful to nearby villagers Health has had an impact.
