Integral biochemical index of the state of aquatic organisms under polluted conditions

Abstract

The state of marine and estuary organisms living in the polluted coastal zone of Peter the Great Bay in the Sea of Japan has been estimated using molecular biomarkers of oxidative stress and biotransformation that characterize changes in animal metabolism under the effect of pollutants. The integral biochemical indices were calculated and graphically represented for mussels Crenomytilus grayanus collected at marine stations with different degrees of pollution and for the Japanese mitten crab Eriocheir japonica from the estuaries of rivers flowing into Peter the Great Bay, based on statistical processing of the results. It has been noted that the values of the indices correspond to the degree of pollution of animal sampling areas.
