Abstract
The heavy metals and organic pollutants in sediment of 6 points of Maimiao-Beitang River were monitored. The results showed that the uneven distribution of heavy metals and volatile areas, in addition to two mornitoring sites ,which zinc contents were over "Control standards for pollutants in sludges from agricultural" (GB4284-84), other indicators of heavy metals met the standards. Organic pollutants chloroform, dichloroethane, benzene, toluene, xylene, ethylbenzene, BHC, DDT levels in four monitoring sites sediment reached the relevant standards. Potential ecological risk of heavy metals in sediment followed the order Hg> Cd> Cu> Zn> Ni> As> Cr> Pb, the point position of the potential ecological risks of pollution followed the order S2> S3> S5> S6> Sl> S4, Hg was the main potential ecological risk factor. Discussion result is that sediment in S2 ~ S4 can't be utilized in agriculture and landscaping, it should be proper disposed based on identification of hazardous properties.关键词
