Abstract

A comprehensive analysis of data on the content of PO₄^3- and SiO₃^2- in the atmospheric precipitation, collected in Sevastopol, with the data of back trajectories of HYSPLIT and AERONET models, as well as aerosol optical depth (AOD) was carried out. It has been found that the days with increased concentrations of PO₄^3-and SiO₃^2- coincide with the dates of transfer of the dust aerosol from the Sahara desert. The concentration of inorganic phosphorus and silicon in the precipitations in these cases may increase in several times as compared with their volume-weighted mean concentrations.
