abstract = "Studies of metal accumulation in fish are mainly focused on the muscle
tissue, while the metal accumulation patterns in other tissues have been
largely neglected. Muscle is not always a good indicator of the whole
fish body contamination. Elemental accumulation in many fish tissues and
organs and their potential use in monitoring programs have not received
proper attention. In the present study, As, Cd, Co, Cr, Cu, Fe, Hg, Mn,
Ni, Pb, Se, and Zn concentrations were assessed by inductively coupled
plasma mass spectrometry (ICP-MS) in the following 14 tissues of the
wels catfish (Silurus glanis) from the Danube River: muscle, gills,
spleen, liver, kidneys, intestine, gizzard, heart, brain, gallbladder,
swim bladder, vertebra, operculum, and gonads. A high level of
differential elemental accumulation among the studied tissues was
observed. The maximum overall metal accumulation was observed in the
vertebra, followed by the kidneys and liver, with the metal pollution
index (MPI) values of 0.26, 0.25, and 0.24, respectively. The minimum
values were observed in the gallbladder, muscle, brain, and swim
bladder, with MPI values of 0.03, 0.06, 0.07, and 0.09, respectively.
Average metal concentrations in the fish muscle were below the maximum
allowed concentrations for human consumption. The mean As, Cd, Pb, Cu,
Fe, and Zn concentrations in the muscle were 0.028, 0.001, 0.001, 0.192,
3.966, and 3.969 mu g/g wet weight, respectively. We believe that the
presented findings could be of interest for the scientific community and
freshwater ecosystem managers. There is a need for further research that
would assess less studied tissues in different fish species.",
