| 摘 要： | 锦州市工业废水和生活污水大部分通过管网排入小凌河。通过对该河易污染区河底泥实地调查采样,采用原子吸收光谱法对底泥中的铜、铅、镉、铬、镍、锌进行测定分析,评价小凌河底泥重金属的环境状况。结果显示,重金属污染大小程度:锌>铬>镍>铜>铅>镉,该区域河底泥为中度污染,污染等级为Ⅲ级。

| Abstract: | Most of the industrial wastewater and domestic sewage in Jinzhou City was discharged into Xiaoling River through pipe network. By field investigation on sediment samples of Xiaoling River, Cu, Pb, Cr, Ni, Cd and Zn were determined with atomic absorption spectrometry, the environmental conditions of heavy metal in sediments were evaluated. The results showed that the order of heavy metal pollution is Zn 〉 Cr 〉 Ni 〉 Cu 〉 Pb 〉 Cd, river sediments in the region are moderately polluted with pollution grade of Ⅲ. |
