Metal intoxication of atmospheric precipitations near coal power stations

Intoxication of atmospheric precipitation near power stations is presented. The migration of some metals in air is described by intoxication coefficient, which in 1981 for Pb changed from 2.25 to 2.96, for Cd from 1.92 to 3.0, for Cu from 2.31 to 4.44, for Fe from 2.78 to 3.95, and for Mn from 1.77 to 3.76. The coefficient value defines potential ecotoxicity of a given metal in the region investigated. Rain or snow intoxication by Pb, Cu, Cd, Fe and Mn, depending o their amount, is described by equation y=axb. (author). 4 refs, 3 figs, 3 tabs
