The elements content (Fe, Mn, Al, Zn, Cu, Cr, Pb, Ni, Cd, Ba, Sr, V) in the tissues of fish (muscles, liver, gills) of various trophic level (bream (Abramis brama) and a pike perch (Zander lucioperca) from the Sheshma River (the Middle Volga Region, Russia) is given. A lot of different technologies, including solvent cyclic steam-assisted gravity drainage and cyclic steam stimulation, are used for oil production in the catchment area of the Sheshma River.
It was shown that both species of fish accumulated Pb (muscles and a liver) and Cd (a liver and gills) significantly. A bream accumulated more Ni and V in a liver, Ba and Sr in gills compared with a pike perch. The coefficients of bioaccumulation (BAF) were higher for all elements in a liver of a bream in comparison with a pike perch, with the exception of Zn and Cd. The value of metal pollution index was about 5 times lower for a pike perch liver in comparison with a bream. Target Hazard Quotient (THQ) was calculated for the characteristic of non- cancerogenic risk for the use of fish in food for adult and children. To assess the overall potential health risk posed by more than one metal, THQ of every metal was summed up for hazard index (HI), which was lower than one and characterized as low. For children and also habitual fish consumers, THQ was five times higher in comparison with normal fish consumers but characterized as low too. |
