Abstract

Abstract

The parameters of water quality such as pH, WT, DO, SD, NH4+-N,TN,DP,TP,CODCr,CODMn,BOD5,TOC和Chl-a were chosen as primary assessment factors to evaluate the water quality of six medium and small creeks in Shanghai by principal component analysis, comprehensive pollution index, comprehensive nutritive index, organic pollution index and comprehensive water quality identification index from Match 2013 to February 2014. The evaluation methods were compared, and pollution sources of creeks were also analyzed. Results showed that great spatial difference was obtained among the water qualities of six creeks. The water quality of Danjiang creek was the worst, followed by Gongye creek, and that of Liwa creek was the best. TN and TP were the main primary pollution factors. The major form of total phosphorus in the six creeks was existed as dissolved phosphorus. The main form of nitrogen in creeks of Gongye, Changbang, Zhenru and Danjiang was of ammonia nitrogen. However, nitrate nitrogen was considered as the main form of nitrogen in creeks of Yingtao and Liwa.
