| 摘 要： | 目的]研究太湖西北部主要7条入湖河道沉积物的主要污染源和污染程度。方法]2005～2006年,对太湖西北部的7条入湖河道沉积物进行采样调查,采用常量元素摩尔比来划分每条河道的主要污染源,并采用富集系数评价7条河道中沉积物重金属污染状况。结果]马山河、梁溪河、西湾河主要受市政污染,直湖港、漕桥河主要受工业污染,大浦河、武进河主要受农业污染;以工业污染源为主的河道重金属污染程度最大,以农业污染源为主的河道次之,以市政污染为主的河道最小。结论]该研究为太湖流域河道污染的治理提供了理论依据。

| Abstract: | Objective] The study aimed to analyze the pollution sources and degree of sediments in seven rivers flowing into Taihu Lake.Method] Based on a survey for the sediments in seven rivers flowing into the northwestern Taihu Lake from 2005 to 2007,the molar ratio of major elements was used to determine the main pollution sources of each channel,and the heavy metal pollution of sediments in the seven rivers was assessed by enrichment coefficient.Result] Mashan River,Liangxi River and Xiwan River mainly suffered municipal pollution;Zhihu Port and Caoqiao River were chiefly subjected by to industrial pollution;Dapu River and Wujin River were mainly affected agricultural pollution.The pollution of the rivers by heavy metals mainly from industries was the most seriously,followed by the pollution caused by agricultural activities,while the pollution of the rivers resulting from municipal pollution sources was the minimum.Conclusion] The research could provide scientific references for the control of river pollution by heavy metals along Taihu Lake basin. |
