  abstract     = {Two freshwater fishes, Rasbora sumatrana
(Cyprinidae) and Poecilia reticulata (guppy) (Poeciliidae) were
exposed for a four-day period in the laboratory condition to a range
of copper (Cu) and cadmium (Cd) concentrations. Mortality was
assessed and median lethal concentrations (LC50) were calculated.
LC50 increased with decrease in mean exposure times for both metals.
For R. sumatrana, LC50s for 24, 48, 72 and 96 hours for Cu were
54.2, 30.3, 18.9 and 5.6 μg/L and for Cd 1440.2, 459.3, 392.3 and
101.6 μg/L respectively. For P. reticulata, LC50s for 24, 48, 72 and
96 hours for Cu were 348.9, 145.4, 61.3 and 37.9 μg/L and for Cd
8205.6, 2827.1, 405.8 and 168.1 μg/L, respectively. Results indicated
that the Cu was more toxic than Cd to both fishes (Cu>Cd) and R.
sumatrana was more sensitive than P. reticulata to the metals.},
