Distribution and potential health risk of nitrate in centralized groundwater sources of Wanbei Plain, Central China

Centralized groundwater sources are the main source for drinking, domestic, industry, and agriculture in Central China. Thirty-five centralized groundwater sources were selected to determine the concentration and distribution characterization of nitrate in Wanbei Plain, Anhui Province. Meanwhile, th...
