Concentrations of trace metals in the flesh of nine fish species commonly found in commercial
catches of a hydro-power reservoir in Sri Lanka (Victoria) were detected using the
Neutron Activation Technique. High concentrations of Al (37.8 - 208.0 μg•g-1 dry wt.) and Rb
(20.90 - 70.75 μg•g-1 dry wt.) were found in all nine species while the concentration of Zn
ranged from 20.29 to 92.00 μg•g-1 dry wt. but was found only in four species. Au was detected
in seven species but the concentration ranged from 0.004 to 0.043 μg•g-1 dry wt. The concentration
of Mn (4.30-6.62 μg•g-1 dry wt.) and V (0.245 to 0.43 μg•g-1 dry wt.) were also relatively
low and found in three and two species respectively.
