【摘要】：为评估"有色金属之乡"——南丹典型村庄常住居民体内重金属水平,对矿业活动影响区车河镇、大厂镇和长老乡及对照区六寨镇典型村庄居民尿液Cd、As和Sb含量进行了抽样调查。结果表明,长老乡居民尿Cd平均含量超过参考值的人所占比例高达71.43%,车河镇、大厂镇人尿As含量分别是对照区的1.49倍、1.50倍,车河镇、大厂镇居民尿Sb含量分别是对照区的1.60倍、2.72倍。从不同人群比较结果来看,男性与女性之间尿样Cd、As、Sb含量差异均不显著;不同年龄段之间As、Sb差异均不显著;老年组与壮年组之间Cd差异不显著,但都显著高于未成年组。综合起来看,南丹3个矿业活动影响区的常住居民体内重金属含量水平高于对照区,需要引起关注。
[Abstract]:In order to assess the levels of heavy metals in the residents of the typical village of Nandan, which is a "township of non-ferrous metals", Chehe Town, an area affected by mining activities, The urine CD, as and SB contents of typical villages in Dachang Town, Changlaoxiang Township and the control area were investigated. The results showed that the proportion of people whose urine CD content exceeded the reference value was as high as 71.43. The urine as content in Chhe Town and Dachang Town was 1.49 times or 1.50 times of that in the control area, respectively. The urinary SB content in Dachang Town was 1.60 times and 2.72 times as much as that in the control area. The results showed that there was no significant difference between male and female in the content of aspartate SB in urine samples; there was no significant difference in aspartate SB in different age groups; there was no significant difference in CD between the aged group and the adult group, but all of them were significantly higher than that in the minor group. To sum up, the content of heavy metals in the residents of the three mining activity affected areas of Nandan is higher than that in the control area, which needs to be paid attention to.
