摘要
对淮南矿区潘集杨庄塌陷水域沉积物中的营养盐及重金属元素进行了分析,揭示了其环境现状和受污染程度。结果表明:潘集杨庄塌陷水域沉积物OI和ON属于尚清洁级别。沉积物的重金属污染主要以Cd元素为主,并依据潜在生态风险指数,表明该区域重金属总潜在风险达到强生态危害程度。
This article reveals the environmental status and extent of contamination in the subsidence in Yangzhuang of Huainan Mining Area through the analysis of nutrients and heavy metals in its sediments. The results show that the subsidence waters is in the state of less clear by evaluating the sediments of Yangzhuang with OI and ON. Cd is the main pollution factors in sediments. According to the potential ecological risk index, the potential ecological risk of heavy metal in sediments of subsidence area of Yangzhuang is in the strong rank.
