| Abstract: | 38 samples in surface water and 13 samples in drinking water wells in rural areas are collected in the Jiantan River in the Three Gorges Reservoir area during the low water period.Nitrate nitrogen and nitrite nitrogen in the samples are measured and analyzed to depict the distribution of nitrate and nitrite pollution in the studied basin.Correlativity analysis reveals the relationship between the nitrate nitrogen and the nitrite nitrogen level of the surface water samples in the study basin.The NO3-N is serious exceeded in rural drinking water wells along the Jiantan River Basin,and the importance of the safety of drinking well water in rural areas is proposed. |
