目的针对贵州赫章县多年矿山开采重金属污染地区开展人体铊含量特征调查。方法在开采污染最严重的妈姑镇和未曾有过开采的撒拉溪镇随机选取45岁以上村民作为研究对象,采集村民的尿液进行铊含量检测。结果妈姑镇人群尿铊含量高于撒拉溪镇,女性尿铊含量高于男性,两地区人群尿铊多数在正常人尿铊的生物接触上限值内。结论调查地区村民没有慢性铊接触中毒,妈姑镇45岁以上女性非职业人群尿铊95%上限为8μg/gCr,其余45岁以上非职业人群尿铊95%上限为5μg/gCr。
Aim To investigate the characteristics of thallium content in human heavy metals in Hezhang County, Guizhou Province for many years. Methods We selected randomly selected villagers over 45 years old from Mowe, the most polluted mining town, and Saraxi town, which had never been exploited, to collect the urine of villagers for the detection of thallium content. Results The population of Thau Town in Mogu Town was higher than that in Salah Town, and the urinary thallium in women was higher than that in men. The majority of urinary thallium in the two districts was within the biological contact limit of normal thallium. Conclusions There is no chronic thallium poisoning among villagers in survey area. The 95% upper limit of urinary thallium for women over 45 years old in Mogu town is 8μg / gCr, and the upper limit of 95% of thallium in non-occupational population over 45 years old is 5μg / gCr.
