The degree of air pollution is assessed by comparing the actual concentrations of impurities (in mg/m3, μg/m3) against the maximum permissible concentrations (MPC) of the pollutant in the air.
MPC is a concentration that does not directly or indirectly adversely affect the present or future generations throughout life, does not reduce a person’s performance capacity, does not worsen his/her well-being and sanitary living conditions. The MPC values are given in mg of substance per 1 m3 of air (mg/m3).
MPC m.o. is the maximum permissible one-time concentration of a pollutant in the air of populated areas, in mg/m3;
MPC d.a. - maximum permissible average daily concentration of a pollutant in the air of populated areas, mg/m3.
