摘要和关键词

摘要: 为探究皖南地区工业聚集区土壤重金属生态及健康风险,文章选取典型代表地青阳县,通过实地调研获取其矿业、工业、居民、产业园4类用地重金属质量比数据,分析表层土壤重金属Cu、Ni、As、Cd、Hg、Pb的空间分布特征、污染程度、重金属溯源、生态风险和健康风险。结果表明,研究区域表层土壤重金属质量比的空间分布差异显著,总体呈现北高南低、西高东低的趋势。研究区北部存在较强的潜在生态风险,其中工业区和居民区的潜在风险指数相对较高。在健康方面的影响上,经口摄入是主要风险途径,Pb和As的影响远高于其他重金属,且儿童大于成人。重金属Ni主要来自于矿业行业和产业园区,重金属Pb、Hg主要来自于工业区和居民区,重金属Cd主要来自于工业区,重金属Cu和As的来源相对平均。

Abstract and Keywords

Abstract: In order to explore the ecological and health risks of heavy metals in the soil of industrial agglomeration areas in southern Anhui, this paper selected Qingyang County, a typical representative area, to obtain the heavy metal content of four types of land for mining, industry, residence and industrial parks through field investigation, and analyzed the spatial distribution characteristics, pollution degree, traceability, ecological risks and health risks of heavy metals Cu, Ni, As, Cd, Hg and Pb in the surface soil. The results show that the spatial distribution of heavy metal content in the surface soil in the study area is significantly different, and presents a trend of high in the north and low in the south, high in the west and low in the east. There are strong potential ecological risks in the northern part of the study area, and the potential risk index of industrial and residential areas is relatively high. In terms of health effects, oral ingestion is the main risk pathway, the effects of Pb and As are much higher than those of other heavy metals, and the impact on children is higher than on adults. Heavy metal Ni mainly comes from the mining industry and industrial parks, heavy metals Pb
