| description | Cadmium, arsenic, plumbum and mercury content in organs and tissues of the Baltic Sea fish was analyzed. Characteristics of toxic elements dissemination in organs and tissues of the following fish species: freshwater fish (redeye Scardinius erythrophthalmus, bream Abramis brama, perch Perca fluviatilis, cat fish Silurus glanis, crucian carp Carassius carassius, tench Tinca tinca, white bream Blicca bjorkna, pike Esox lucius) and sea fish (mackerel Scombers combrus, herring Clupea harengus membras, salmon Salmo salar, poutassou Micromesistius, cod Gadus morhua callarias, Baltic sprat Sprattus sprattus balticus), as well as species specificity in accumulation of elements under study were identified. It was determined that tested organs (liver) and tissues (muscles) accumulate different toxic elements to a different extent. Cd, Pb, As, Hg content of in fish organs and tissues does not exceed MRL. Their distribution in a fish body is unequal and depends on functional characteristics of organs, cumulative activity and element chemical properties. Among the tested tissues the greatest ability to accumulate was observed in phytophages and benthophages which is caused by high content of toxic elements in their diet. The next are predatory fish species due to of their diet peculiarities. High Cd, As, Pb, Hg content in fish is indicative of their considerable concentration in habitat, accumulation in food chains and functional deficiencies in the ecosystem. |
