Estimation of the water condition in Peter the Great bay (Japan Sea) on the basis of hydrochemical indicators and the analysis of growth and content of chlorophyll a in microalgae Phaeodactylum tricornutum

The hydrochemical analysis, and also estimation of growth and content of chlorophyll A in microalgae P. tricornutum, grown up in water from different areas of Peter the Great bay with high anthropogenous loading are carried out. Our researches have shown that growth of microalgae P. tricornutum in the water which has been selected at all investigated stations, differed from that in control, besides that hydrochemical indicators were within admissible norm. On the basis of the received data the investigated areas on degree of deterioration of ecological situation it is possible to arrange in a following order: southwest part of Peter the Great bay
