【摘要】 用等离子体原子发射法测定了钉螺软体组织与其孳生地土壤中重金属元素Cr、Cu、Zn、Mn、Cd和Pb的含量,对其污染状况进行了分析.结果表明:钉螺是监测其孳生地土壤重金属污染的理想的指示生物,根据重金属在钉螺体内的累积情况可以判定土壤受重金属污染的程度.更多还原

【Abstract】 The heavy metal elements of Cr,Cu,Zn,Mn,Cd and Pb in the tender tissues of O.hupensis and soil were determined and analyzed by plasma-atomic emission spectrometry.The results showed that O.hupensis is an ideal indicator for the pollution of heavy metals in soil,The bioaccumulation of heavy metals in O.hupensis reflected the pollution of heavy metals in soil.更多还原
