The analysis of long-term monitoring results of the Artillery Bay are represented. In the sea water of the Artillery Bay dissolved organic matter is approximately 70% of the total organic matter. The amount of oil hydrocarbons in 80 % of cases exceeded the MPC. Phenols were found up to 5 micrograms per liter. The tendency of increasing lipid concentrations in sea water with an increase in the number of diatoms has a correlation coefficient of r = 0,62. Thaloms of algae macrophytes contained same compound of organic substances, found in sea water. The total number of heterotrophic and oil-oxidizing bacteria in seawater and bottom sediments corresponded to the average performance of these groups of microorganisms in the Sevastopol Bay. The bay is among the most polluted in the region of Sevastopol by the level of content of major classes of organic substances, as well as oil hydrocarbons in bottom sediments. Meiobenthic community of the bottom sediments is suppressed, as evidenced by the simplification of the taxonomic composition and the increase in the total number due to nematodes. Intensity of economical activity on the coast of bay influences on a quantity and biomass of macrozoobenthos. The new data about transformation of pollutants on the border of contact zone “sea - substrate – atmosphere” is got. The leading role of microperiphyton in these processes was marked.
