abstract = "In this study, the concentrations of metals and trace elements (As, Cd, Co, Cr, Cu, Hg, Ni,
Pb and Zn) were determined in the muscle tissue of adult roach and white bream at two different
sites in the Belgrade section of the Danube. Twenty-six fatty acids, consisting of nine saturated FA
(SFAs), seven monosaturated FA (MUFAs) and ten polysaturated FA (PUFAs), were identified. The
analysis of the concentration of metals and trace elements of the roach and white bream showed
species-specific differences in their bioaccumulation. Four of all elements analyzed (As, Hg, Ni and
Pb) correlated significantly with the changes in FA profiles in fish from both sampling sites, with the
exception of Cu, which correlated with the FA profile at the site before, and Zn, whose concentration
influenced the FA profile at the site after wastewater discharges. The lower PUFA content in the fish
from a site under higher environment pressure could indicate that the fish are stressed. The results
suggest that changes in lipid composition may be one of the protective mechanisms of cells to cope
with anthropogenic stressors.",
