CHEMICAL-TOXICOLOGICAL CHARACTERISTICS AND SANITARY-BACTERIOLOGICAL STATE OF THE MARINE AND MOLLUSKS OF THE KERCH STRAIT AND THE PRE-STRAIT OF THE BLACK SEA
The chemical-toxicological characteristics and the sanitary and bacteriological state of the marine environment and mollusks of the Kerch Strait and the pre-Strait of the Black sea as potential areas for the construction of a marine farm for industrial mussel cultivation are presented. Materials on the maintenance of various toxicants (petroleum hydrocarbons, heavy metals and chlorine compounds) in marine water, bottom sediments and soft tissues of mussels are presented. The data are analyzed and a comparative analysis of long-term comprehensive sanitary-microbiological studies of the marine environment in the areas where mussel plantations are located with indicators of other waters of the Kerch Strait is carried out. It is shown that when choosing areas for mussel farms, it is necessary to take into account the magnitude and nature of toxic pollution of the water area, as well as the sanitary and bacteriological state of sea water and mollusks. The state of the marine environment and mollusks in the studied areas do not contradict sanitary and hygienic requirements, so they can be recommended for the placement of marine farms.
