摘要
采用欧共体参比司的三步连续提取程序,对采集到的兖州矿区内的南屯、北宿、济二和东滩矿的矸石及周边土壤样品,分别测试了重金属Cu、Cd、Cr、Zn、Pb的4种形态及矸石浸出毒性。得出了重金属污染物的化学形态对环境和生命体的危害及毒性程度为:酸可提取态>氧化物结合态>有机结合态>残渣态。
Samples were taken from waste piles and soil nearby at Yankuang Group＇s Nantun,Beisu,Ji＇er and Dongtan mines and tested,using the process of European Community Bureau of Reference,for the speciations of Cu,Cd,Cr,Zn and Pb,and the leaching toxicity of the mine waste.It is determined that the harm of the chemical speciations of heavy metal pollutants to the environment and organisms,and their toxicity are in order of acid extractablereducibleoxidizableresidual.
