| 摘 要： | 对湘西锰矿区和铅锌矿区周边土壤中重金属铅的含量进行测定,采用美国最新的法定重金属污染评价方法 TCLP法对土壤铅污染状况进行了评价。结果表明,土壤中Pb的有效态含量为0.21~4.80 mg/kg,未超过相应的国际标准。湘西锰矿区和铅锌矿区周边土壤中的重金属Pb环境质量尚属安全,但越靠近矿区Pb污染对周围居民人体健康的危害风险越大。

| Abstract: | The contents of lead in surrounding soil of manganese and lead-zinc mining area in western Hunan were determined and the potential ecological risk of lead pollution was accessed with the latest statutory assessment method TCLP（Toxicity characteristic leaching procedure ） of USA.The results showed that the content of available Pb in soil was 0.21-4.80 mg/kg,no more than the corresponding international standards.The Pb environment is safe in surrounding area of manganese and lead-zinc mining area in western Hunan,but closer to the Pb pollution area,the harm risk to surrounding residents increased. |
