Ecological and Human Health Risk Assessment of Heavy Metals in the Land Left by a Closed Smelting Enterprise
摘要
Abstract
In this paper,heavy metals in the land left over by a closed smelting enterprise were taken as the research object.In order to clearly understand the heavy metal pollution in the soil,sampling detection and analysis of the heavy metal content were carried out at different locations.The inverse distance weight difference method was used to process the data,and the impact of heavy metals on ecological risks and human health risks was further discussed.The results showed that there were As,Sb,Pb and Cr(Ⅵ)pollution in different degrees in this field,and the regional distribution of heavy metals was obviously related to the production activities of enterprise.The single factor potential ecological risk of soil heavy metals was As>Pb>Sb>Cr(Ⅵ),and the comprehensive potential ecological risk was at a medium level.The carcinogenic risk and non-carcinogenic hazard quotient of heavy metals through oral ingestion were higher than those of other ways,the carcinogenic risk and non-carcinogenic hazard quotien of As were 1.18×10-4 and 4.60,respectively,and the contribution rates were higher than those of other heavy metals.关键词
