Abstract
Human activity significantly affects the substances content in the atmosphere, their natural cycles and budget. The chemical composition of atmospherical condensation is one of the main characteristics of atmospheric air pollution level. But in addition they also serve as a significant source of various substances inflow in maritime and continental ecosystems, capable to change their ecological state. Mainly this fact determines the urgency of studying the chemical composition of atmospheric precipitation. It is presented a comparative content characteristic of basic biogenic elements (inorganic nitrogen and phosphorus) in the atmospherical condensation in the background and urbanized areas on the Black Sea coast (v. Katsiveli and Sevastopol) and in the Rostov-on-Don region in May-September 2016. The difference of concentrations in condensations of background and urbanized regions is considered, the reasons of this difference are analyzed. The possible influence of condensations on the geological substate is estimated. It is shown that ammoniacal and nitrate were the basic forms of nitrogen in the atmospherical condensations of all observation points. In Rostov-on-Don, the content of ammonium was significantly higher than the content of nitrates, which can be explained by the entry of this element into the atmosphere from rice checks, located near the sampling site. The concentration of inorganic phosphorus in the atmospherical condensations of Rostov-on-Don exceeded the concentration in the Crimean coast region in 5 times, which may be connected with the influence of rice checks and a grain terminal near the sampling stations, as well as the introduction of phosphates into the atmosphere by winds blowing in the direction from the Salsky steppes.
