• Wet deposition of acid and of ecotoxic heavy metals Cd, Pb, Cu and Zn by rain and snow in the F.R.G. was followed during the semidecade 1980 – 84 to establish the long term trends and to study regional and local situations. The free acid in rain and snow is rather uniformly distributed over the whole area as a result of mesoscalic transport of the acid precursors. Whereas a common background heavy metal deposition has not significantly altered over the studied period the distincly higher depositions and concentrations observed in polluted regions show since 1981 a decreasing trend.
