RÉSUMÉ

Several areas in the intertidal zone of Kandalaksha Gulf subjected to anthropic influences were under study during the summer seasons of 1991 -1993. Littoral communities of microzoobenthos in those areas contained only from 20 to 30% of the species commonly inhabiting the grounds typical for them. The species composition and numbers of infusorians in the biotopes studied were very variable, and it is characteristically the appearance of local 'dots' extremely saturated with the species consuming bacteria, detritus, plant, and animal remains. 40% of differences in the species composition of communities were related to the ground concentration of pollutants and 58% were dependent on ratios of the content of heavy metals and organic compounds in biotopes. Toxicants differing by their nature lead to similar degradation changes in the structure of communities. Integral characteristics of communities determined by processing the whole assemblage of indexes give fuller information to evaluate a community state than such indexes as biomass and numbers of microzoobenthic organisms.
