Biochemical changes of the organism of Apodemus flavicollis (Rodentia: Muridae) under conditions of environmental anthropogenic pollution by heavy metals in northern areas of Ukraine

Abstract

The present research dedicates the integral assessment of biochemistry indexes of nature populations of rodents under conditions of environment pollution by heavy metals. The raised content in soils of mobile forms Pb, Cd, Cr, Ni and Co was revealed оn distance of 500 m to the South-West from Tripillya Thermal Power Plant (Kyiv region, Ukraine). That’s considerably (3–5 times) exceeds levels for territory of Kaniv Nature Reserve (Cherkassy region, Ukraine). Territory of National Nature Park “Holosiivsky” (Kyiv, Ukraine) characterized by rather increased content of active form of researched heavy metals especially Pb. Increase of the concentration of diene conjugates (3–7 times) and malonic dialdehyde (2–4 times) in yellow-necked mouse liver (Apodemus flavicollis) of under pollution by heavy metals has been discovered. Insignificant increasing of content of Schiff basis in liver cells of rodents in region of impact of Tripillya TPP (in 2 times in spring and in summer, in autumn – in 2.5 times) was detected. Seasonal dynamics of the maintenance of lipid peroxidation has been revealed. The registered changes of biochemical indicators testify about presence ecological-biochemical stress in an organism of the yellow-necked mouse in the district of influence of Tripillya TPP.
