- The purposes of our researches were the determination of the level of purity of wastewater discharged into Caspian Sea, also the control over the content of cadmium and its extraction-photometric determination in fish and fish product. Samples of wastewater were taken on wastewater treatment plant in the Hovsan village, where are applied the complex of methods for purification of wastewater. Enterobacteriacae causes especial interest in the case of anthropogenic pollution of Caspian Sea by wastewater. Salmonella, Proteus, Citrobacter - are risk factors for health of population. So, in analyzed material representatives of Enterobacteriaceae in samples of water were 18.3%±, in fish were 32.5%± from all isolated microflora. Klebsiella and Serratia were found in the studied objects as single strains, Vibrio parahaemolyticus were found in fish in the amount of 16.2%. We worked out the technique of two stage extraction-photometric determination of cadmium with 1,10-phenanthroline (phen) and alizarin yellow P (A and P). The technique allows to identify 0,5-20µg of cadmium in the volume 50 ml of aqueous phase with sufficient accuracy. Thus, the received data give the evidence of significant pathogenicity of dominant in our material Vibrio parahaemolyticus, which disseminates the fish and water in its habitats, and of epidemiological risk, which is created in environment by above-mentioned microorganism. Considering aforesaid, can be made a conclusion that it is required a constant control over the content of exactly cadmium in seafood, because, the excess of cadmium in human organism, led to substitution of zinc from many enzymes and can cause the cancer.
