| Abstract: | Present study consists the bioaccumulation of cadmium and lead in
young juvenile Milkfish liver (Chanos chanos). It is carried out after
exposure to three sublethal concentration of each pollutants (on 1/20, 1/10 and 1/5 LC50 of 96-h LC50)
for acute time 12, 24 and 96 hour and subchronic time 7, 14 and 21 days. Cadmium and lead
accumulation in liver increased with exposure periods and concentration of
pollutants. Compared with controls, the uptake of
cadmium is much higher than that of lead. Accumulation factors showed
an increase with the exposure period and an inverse relationship between the
accumulation factor and exposure concentration for lead. Elimination of these
two pollutants was investigated after 30 days depuration time. During
the depuration phase, cadmium and lead concentration decreased. |
