Investigation on the Contamination by Dissloved Inorganic Nitrogen in Xiangjiang River |
| |
| Abstract: | It investigated the distributional characteristics and spacetime variations of dissloved inorganic nitrogen(DIN) to 29 monitoring sites in five monitoring regions of Xiangjiang river including Hengyang,Zhuzhou,Xiangtan,Changsha and Yueyang,during three period of drought period,breeding period and seeking period in Jan,May,Sep,2009.The results showed: the DIN concentrations in Xiangjiang river Hunan section were 1.71 mg/L in seeking period,1.14 mg/L in drought period,and 0.77 mg/L in breeding period.In addition,there was ascending tendency of the DIN concentration from the upper stream Hengyang section to the downstream Yueyang section. |
