摘要
本文对南广河水体中的砷镉铅铬含量分布特征进行了描述,并探讨了南广河的水质质量。结果表明:南广河从上游到下游水体中污染物含量为增大趋势;在时间上也存在一定的变化,枯水期水体中污染物含量高于平水期和丰水期。目前南广河综合水质质量可满足Ⅱ类水质标准要求。
This paper describes the distribution characteristics of As,Cd,Pb and Cr of Nanguang River and makes a probe to its water quality The result shows there is more pollutants than before from upper reaches to lower reaches of the river,while pollutant concentrations in dry water season are higher than those in average one At present the integrated quality of water can accord with the request of Class B,National Standard for Surface Water
