Dependence of heavy metal content in soils and snow cover on the distance of their source


, : Dependence of heavy metal content in soils and snow cover on the distance of their source. Pochvovedenie 0(9): 141-144

A mathematical model of the distribution in the atmosphere and precipitation of aerosols produced by a point source has been used. Results of calculations with this model applied were compared with simple functions. The approximation of this correlation by a degree function was proved to be more reliable than by the exponential one.
