摘    要:矿产资源的长期勘探、开采和冶炼活动给大冶铁山地区的自然生态环境造成了严重破坏.对该区西港河、东港河河水和水系沉积物中重金属元素分布特征的研究结果表明,该区矿山开采和冶炼活动形成的重金属污染元素主要为Cd、As、Zn;其主要污染源为冶炼厂排放的废水,其次是采矿废弃物堆积渗漏水;重金属元素在河水与水系沉积物中的空间分布特征较相似,但水系沉积物中元素质量分数比河水中的普遍增高,元素变化的剧烈程度加剧.

关 键 词:重金属污染  河流水体  水系沉积物  铁山  大冶

Abstract:The long-time exploration,mining and smelting activities,have damaged the environment quality of Tieshan,Daye,Hubei Province.This paper studies the heavy metal distribution of creek water and its sediments in this area.The result shows that the Cd,As,Zn is the most distinct pollution elements;and the pollution matter mainly comes from the waste water of the smelting factory.The next source is the drainage of mining.The spatial distribution characteristic of some heavy metal elements in creek water and sediments,especially for Cd,As,Sb,Hg,is similar,but for most heavy metal elements,the content in sediments is higher.The variety of these elements in sediments is also more acute.
Keywords:heavy metal pollution  creek water  sediment  Tieshan  Daye
