摘　　要：为研究抚顺市区南部地表堆积的油页岩中微量元素的淋滤作用对水体的影响,本文分别进行了抚顺西露天矿采场和西舍场油页岩pH为4.0、6.5和8.0的动态淋滤实验,以ICP-MS测试了淋滤液及水体中的微量元素。结果表明,高、低品位油页岩中Cu、Zn、Pb、Ni、Rb、Bi、Ba、Ti、Co、Cr、Cu和Mn等淋出率较高;水体中Pb、Cd、Co、Cr、Ni、Zn、Mn等元素超标,表明抚顺西舍场油页岩的堆积已对周围地表水体和地下水体造成了污染。In order to investigate the leaching behavior of trace elements from oil shale piled at the southern Fushun city and its effects on the surrounding water, dynamic experiment of leaching oil shale samples from the West Open Pit and the West Dumping Site, Fushun, have been undertaken at 4.0, 6.5 and 8.0 for the pH values of leaching solutions respectively. Then trace elements in leachates and water samples collected from the surrounding area of the West Open Pit and the West Dumping Site, Fushun, have been measured by using ICP-MS. Results show that the leaching ratios of Cu, Zn, Pb, Ni, Rb, Bi, Ba, Ti, Co, Cr, Cu, Mn from high-grade and low-grade oil shale samples are quite high; The Pb, Cd, Co, Cr, Ni, Zn, Mn concentrations of the water samples are higher than those of the national standard. Therefore, the waters surrounded the West Open Pit and the West Dumping Site, Fushun, have been polluted by the leaching of trace elements from the oil shale piled in the two sites, and will be continuously polluted if there is no any treatment.
