Bioindication of the water quality of Posyet Bay (Peter the Great Bay, Sea of Japan)
Pollution bioindication of Posyet Bay's coastal waters had been conducted, including the stations related to the marine reserve area, with application of two methods: using the microorganisms, sensitive to environmental changes and brown algae-macrophytes with ability to accumulate heavy metals. Demonstrated, that the results, received from these two approaches, are confirming each other. The data about bacteria coli-form content confirms, that, in generally, Posyet bay is a clean area (excluding Novgorodskaya bay) and polluted by hard-oxidizable petroleum hydrocarbons insignificantly. At the same time, Port Posyet and its surrounding waters as well as areas of the Vityaz bight and the Troizy's bight are as territories with significant recreational impact. Metal content in the brown algae on all the stations, apart from Mramorniy peninsula, are above the reference values.
