EC value, pH value, pE value, nitrate nitrogen and nitrite nitrogen of surface water and groundwater in the Jiantan River in the Three Gorges Reservoir Area were measured and analyzed to depict the spatial distribution of nitrate and nitrite pollution in the study basin. The results show the nitrate nitrogen level of the groundwater in the study basin is holistically larger than those of the surface...
A study assessed the risk of nitrate (NO3--N) pollution in groundwater was conducted in Zhangye Oasis, Northwest China. The mean value of NO3--N concentrations of groundwater samples was 10.66plusmn0.19 mg/L, NO3--N concentrations exceeding 10 mg/L (the threshold of drinking water set by World Health Organization) was found in 32.4% of 71 wells, and were 13%, 33.3%, 52.4%, and 50.0% in the groundwater...
Six newly constructed experimental macrocosms (approximately 0.13 ha each) were built to study nitrogen transformation processes in the adjacent Prado Basin constructed wetland, southern California, USA. First year macrocosm data showed that nitrate was the dominant nitrogen species. Nitrate removal rates during September 1992 were measured at 2800 mg N m -2 d -1 while inorganic...
