| 摘 要： | 水体底泥(沉积物)污染,是世界范围内的一个重要环境问题.其污染物主要通过大气沉降、废水排放、水土流失、雨水淋溶与冲刷进入水体,最后沉积到底泥中并逐渐富集,使底泥受到严重污染.总结了底泥中氨氮、重金属的影响因素及释放机理,也指明了持久性有机污染物释放机理研究不足的现状,提出对其释放机理研究的重要性.

| Abstract: | The contamination of sludge is a worldwide environmental problem. The pullutants come into the rivers and lakes through atmospheric sedimentation, wastewater discharge, soil and water loss and rain erosion and gather at the bottom. In this paper the contrihuting factors and release mechanisms of nitrogen anti phosphorus and heavy metals in the sludge are summarized, the problems existed in the research of release mechanism of POPs and the importance of research on it is also raised. |

| Keywords: | nitrogen and phosphorus persistent organic pollutants(POPs) heavy metal release mechanism sludge |
