目的了解贵州省赫章县长期矿山开采重金属污染地区人群尿砷含量特征。方法在开采污染最严重的妈姑镇和无矿山开采的撒拉溪镇随机选取>45岁村民作为研究对象,采集村民的尿液进行砷含量检测。结果妈姑镇男女尿砷均值分别为46.97和56.30μg/gCr,撒拉溪镇男女尿砷均值分别为36.55和45.83μg/gCr,妈姑镇人群尿砷含量高于撒拉溪镇,女性尿砷含量高于男性。妈姑镇非职业人群尿砷95%上限男女分别为99.40和141.92μg/gCr,撒拉溪镇非职业人群尿砷95%上限男女分别为65.70μg/gCr和78.06μg/gCr。结论调查地区95%村民尿砷<100μg/gCr,无慢性砷中毒。
Objective To understand the characteristics of urinary arsenic in the population of heavy metal pollution in Hezhang County, Guizhou Province. Methods A random sample of 45-year-old villagers from Mowe town, the most polluted mining town and Salaxi town without mine, was selected as the research object to collect the urine of villagers for the detection of arsenic content. Results The mean urinary arsenic concentrations in male and female Mogan women were 46.97 and 56.30 μg / gCr, respectively. The urinary arsenic contents of male and female were 36.55 and 45.83 μg / gCr, respectively. The urine urinary arsenic content in Mogu town was higher than that in Salah town. Higher than men. The upper limit of 95% urinary arsenic in men and women in Mogu town was 99.40 and 141.92 μg / gCr, respectively. The 95% upper limit of urinary arsenic in non-occupational population in Salah town was 65.70 μg / gCr and 78.06 μg / gCr, respectively. Conclusion 95% of the villagers in the investigated area have urinary arsenic <100μg / gCr, no chronic arsenic poisoning.
