Abstract
The content of heavy metals and Al in the aerosol matter over the Sea of Azov has been studied. According to the special test the vast majority of samples were attributed to the type of marine aerosol. The ranges of contents were determined as following: Fe (200 – 2000 ng / m3 ), Al (20 – 200 ng / m3 ), Zn (10 – 280 ng / m3 ), Cu (2 – 23 ng / m3 ), Ni (1 – 16 ng / m3 ), Pb (3 -30 ng / m3 ), Cd (0.4 –2.8 ng / m3 ); Mn (3 – 23 ng / m3 ), Cr (1 – 15 ng / m3 ). The spatial distribution of HMs in the marine aerosol of the Sea of Azov depends on the influence of the river-sea geochemical barrier zone in the Taganrog Bay and the anthropogenic impact of the coastal industrial cities. HM concentrations decrease from the northern coast of the bay and the mouth of the Don River towards the open sea. The maximum HM content in marine aerosol observed in the mouth area of the Don River. It may be associated with the HM accumulation at the river-sea geochemical barrier, and also with the anthropogenic impact of the cities of Rostov-on-Don, Azov and Taganrog. Anthropogenic impact of the city of Mariupol cause the maximum values of Fe, Cr, and Cd in marine aerosol matter of the western part of the Taganrog Bay.
Highlights
The aerosol of the surface layer of the atmosphere, including over water areas, is a mixture of particles of various genesis – from the local sources to the long-range atmospheric transport
Marine aerosol formed from the surface microlayer of the sea inherits its chemical composition

Summary
The aerosol of the surface layer of the atmosphere, including over water areas, is a mixture of particles of various genesis – from the local sources to the long-range atmospheric transport. The phenomena of transcontinental transport of aerosols and abundant atmospheric deposition to the surface of the ocean in the Arctic zone, over the waters of the North Atlantic are known (Vinogradova et al 2019; Maslennikova et al 2018; Sullivan et al 2017; Lukashin et al 2018; Vinogradova et al 2017). It is shown that among the sources of marine aerosol generation (marine, dust, urban, black carbon, volcanic), the ocean surface is the most powerful, delivering up to 1016 kg per year The reverse process of transporting aerosol matter of marine origin towards coastal territories is being investigated
