The results of determination of some hydrochemical characteristics and the diversity of microbiota in rain-water and sea-surface microlayer from the Sevastopol bays are presented. The connection between the level of rainfall contamination by surfactants and their accumulation into sea-surface microlayer has been established. In rain-water pH values varied from 4,2 to 8.2. As a result, the pH value and salinity in sea-surface microlayer decreased by 11–15% after storm and prolonged rains. Seasonal concentration variability of dissolved in rain-water Sr, Se, La, Nd, As, Sb, Mo, Ni, Mg, I, and Fe associated with the direction of the prevailing rainy winds. Potentially pathogenic micromycetes (genera Penicillium, Aspergillus, Cladosporium, Phoma) get into the surface microlayer and marine environment with the rain water. Cyanophyta (genera Synechococcus, Microcystis) and Clorophyta (genus Closterium) were capable to grow both in rain-water with salinity 0.0–0.7‰, and in sea-surface microlayer (range of salinities 17.0−20.5 ‰).
