摘　　要：目的了解济宁市采煤塌陷区水域中重金属含量,为合理利用水资源提供科学依据。方法分别于2011年6月和11月,采集济宁地区二号井煤矿、兴隆庄煤矿、鲍店煤矿和南屯煤矿塌陷区的水样,同时采集同期济宁北湖生态区水样作为对照。对水体中的铁、钙、铅、锰、砷、硒、铜、六价铬进行测定。结果采煤塌陷区枯水期水体中元素的含量要高于丰水期;水体中的铁、铅、砷、硒含量均高于地表水Ⅲ类限值标准,六价铬含量符合我国Ⅰ类限值标准,铜的含量符合我国Ⅱ类限值标准,锰未检出。结论采煤矿塌陷区水体受到铅、砷等重金属元素污染,相关部门应采取有效的治理和降解措施后,再进行综合开发利用。[Objective]To determine the concentration of heavy metals in water of coal-mining subsided area of Jining City,and provide scientific evidence for rational use of water resources.[Methods]The subsided water samples were collected from Jining Ⅱ coal mine,Xinglongzhuang coal mine,Baodian coal mine and Nantun coal mine in June and November 2011 respectively,as well as Beihu ecological Zone as the control.The concentrations of mental elements Fe,Ca,Pb,As,Cu,Mn,Se,Cr6＋were determined.[Results] The concentration of heavy metals in water of coal mining subsided area was higher in the dry season than that in the rain season,with the level of Fe,Pb,As and Se over the limits of class Ⅱ standards of surface water,and the level of Cr6＋ was over the class Ⅰstandard of China.The concentration of Cu did not exceed the limit of class Ⅱ standards,and Mn was not detected.[Conclusion]Water in coal-mining subsided area has been polluted by heavy metals Pb and Se,etc.More efforts should be done to govern and degrade the poisonous metals for the subsequent development and utilization.
