Abstract
The article is focused on the possible ways of accumulating chemical elements (zinc, copper, chromium, nickel, lead, mercury) in the organs of aquatic organisms. In the course of the study, the coefficients of accumulating the chemical elements in the organs and tissues were calculated for the Russian (Acipenser gueldenstaedtii, Brandt, 1833) and Persian sturgeons (Acipenser persicus, Borodin, 1897) relative to the water of the northwestern part of the Caspian Sea, bottom sediments and the main objects of their food (Khvalyn goby (Neogobius caspius), Sandpiper goby (Neogobius fluviatilis), Caspian goblin (Benthophilus microcephalus), roach (Rutilus rutilus caspicus)). The studies were carried out according to the standard method of atomic absorption spectrometry. It is shown that the main source of accumulating the studied chemical elements in the organs and tissues of the Russian and Persian sturgeons is the water of the northwestern part of the Caspian Sea. It was found that the bottom sediments of the Caspian Sea act as an additional source of zinc and mercury found in the liver and kidneys of sturgeon species. Based on the calculated accumulation coefficients of chemical elements, there was revealed a predominantly alimentary nature of accumulating copper, nickel and mercury in the organs of both sturgeon species.

Summary
Рассмотрены возможные способы накопления химических элементов (цинк, медь, хром, никель, свинец, ртуть) в органах гидробионтов. В ходе исследования рассчитаны коэффициенты накопления в тканях и органах русского (Acipenser gueldenstaedtii, Brandt, 1833) и персидского (Acipenser persicus, Borodin, 1897) осетров химических элементов, содержащихся в воде северо-западной части Каспийского моря, донных отложениях и основных объектах питания осетров (бычок хвалынский (Neogobius caspius), бычок-песочник (Neogobius fluviatilis), каспийская пуголовка (Benthophilus microcephalus), вобла (Rutilus rutilus caspicus)). Что основным источником накопления исследованных химических элементов в органах и тканях русского и персидского осетров является вода северо-западной части Каспийского моря. Ф. Коэффициенты накопления химических элементов в органах и тканях русского (Acipenser gueldenstaedtii, Brandt, 1833) и персидского (Acipenser persicus, Borodin, 1897) осетров Каспийского моря // Вестник Астраханского государственного технического университета. На основании вышесказанного целью исследования является расчет коэффициентов накопления химических элементов в органах и тканях русского и персидского осетров относительно воды северо-западной части Каспийского моря, донных отложений и основных объектов их питания
