Human activities significantly affect the content of substances in the atmosphere, their natural cycles and budget. One of the main characteristics of the level of air pollution is chemical composition of precipitation. They also serve as a significant source of various substances in marine and continental ecosystems, capable of changing their ecological state. The possible effect of precipitation on the underlying surface is estimated.
