深圳市大沙河底泥毒物污染特征及对策探讨

运用生物毒性监测方法，对深圳市南山区大沙河底泥毒物污染特征进行了分析，结果表明，大沙河底泥不同程度的受到了毒物污染，底泥毒物污染趋势与水体毒物污染趋势基本一致；还结合化学监测方法，分析了大沙河底泥毒物主要为有机毒物．此外，就大沙河底泥毒物的治理方法提出了自己的见解．

An approach to the features and countermeasures against the bottom sediment poison pollution of the Dashehe River in Shenzhen city Nanshan district

This article, by means of biological toxicity tests, analyzes the feature of the bottom sediment poison pollution in the Dashahe River. Results show as follows: The Dashahe River bottom sediment has been to a different degree. The tendency of the bottom sediment poison pollution is essentially the same as that of the water body poison pollution. Besides, this article, with chemistry monitoring means, analyzes that the poison in the bottom sediment is mostly organic matter. Moreover, it proposes views and ideas of administrating the Dashahe bottom sediment poison pollution.
