The conducted investigations of the oil hydrocarbons and macrozoobenthos organisms spatial distribution allowed to find out zone of the ecological risk in the central part of Sevastopol bay and Yuzhnaya bay. Calculation of the pollution loading index (PLI) on the bay ecosystem, general biological quality index (BQI) and marine biological index (AMBI, М-ambi) was conducted. BQI quantity in 2009 made 1,36 which testify to the fact that main areas of the bay are occupied by the opportunistic zones.
