抚顺西露天采场土岩污染潜势分析

ANALYSIS OF POLLUTION POTENTIAL OF THE ORIGINAL ROCKS IN THE OPENCAST IN THE WEST OF FUSHUN CITY

本文采集了抚顺西露天采场成上原岩样品，实验室分析了该样品的酸化潜力．基岩中潜在毒害重金属(Cu，Pb，Ni，Cd，Zn)的表生活动性．指出该采场的成土原岩处于低，中度产酸范围．并有进一步酸化的可能。基岩中的重金属表生活动性随岩层部位不同有所差异．外围岩层中重金属活性增强。

Based on the samples of the original rocks collected in the opencast in the west of Fushun city, rocks acidification potential and the activity of heavy metals in the original rocks were studied by experiments. It was indicated that the original rocks in the opencast in the west of Fushun city which had low or moderate acid prductivity had the possilbility of further acidification. The activity of the heavy metals in the original rocks varied with the location in the rock layers, and the activity of the heavy metals in the exterior intensified.
