Arsenic in the commercial freshwater fish species of the North-Caucasus Region and in the water bodies they inhabit
The research results on the arsenic content in the water and bottom sediments of freshwater bodies of the Republic of Adygea, Krasnodar Krai, Stavropol Krai, and Rostov Region are given for the period of 2016–2018. The levels of pollution of the habitat of aquatic biological resources have been estimated in accordance with the standards for freshwater bodies of fisheries importance and the average long-term values. The averaged results are presented for the organs and tissues of such commercial fish species as the pike perch (zander), crucian carp, white bream, European perch, common bream and the roach caught in the Krasnodar, Takhtamukaysk, Otkaznensk, Novotroitsk, Chograysk, Kryukovsk, Varnavinsk, Veselovsk, Proletarsk and Ust-Manych Reservoirs, the Don River, the Kuban and Mokraya (Wet) Buyvola Rivers. The levels of arsenic accumulated in the muscles and gonads of the fish have been compared in accordance with the Russian Sanitary Rules and Norms for Food Quality (SanPiN). It is shown that water and bottom sediments in water bodies of the Krasnodar Krai are the most polluted with arsenic. The determination of arsenic in the fish and the water bodies under investigation has been carried out in accordance with the procedures developed in the Azov-Black Sea Branch of “VNIRO” (“AzNIIRKH”).
