青海东部地区土壤重金属污染评价
The evaluation of heavy metals pollution in soil of eastern Qinghai
摘要
Abstract
According to the investigation of heavy metal content in topsoil and deep soil in the east of Qinghai, the authors used Nation⁃al Standard ( GB15618⁃1995) as the evaluation standard. The status of heavy metals in the soil was evaluated, and the situation of heavy metal pollution in Ganhetan was discussed by combining single soil samples, plant samples, water samples and geochemical sec⁃tions. Two heavy metals ( Cd, Hg) were selected to compare the situation of their pollution in different periods. The results indicate that the heavy metal pollution in eastern Qinghai is not serious, but some heavy metals such as Zn, Cd, Pb in Ganhetan have formed obvi⁃ous circular pollution, and the pollution has reached deep soil. Agricultural development is not suitable in this area. It is found that the pollution of some heavy metals such as Cd has aggravated, whereas pollution of some heavy metals like Hg has been reduced.关键词
