Brief description:

Water pollution by nutrients is characterized by annual average concentrations of phosphates and nitrates, which are compared with the maximum permissible concentration (MPC); in Belarus, the MPC for phosphates is 0.066 mg of P/liter, and for nitrates - 40.0 mg of NО3/liter;
The indicator is presented in the context of 10 rivers, 18 lakes as well as groundwater monitoring stations within the Dnieper, the Western Dvina, the Western Bug, the Neman and the Pripyat river basins
