Description 141-145
Present study was intended to compare the acute static renewal toxicity
tests on marine snail, Cerithidae
cingulata and bivalve, Modiolus philippinarum that were performed with Cu, Cd, Pb, Zn and Hg. The 96 h LC50
values for C.cingulata were 0.521, 9.193, 15.507, 8.990 and 0.053 mg.l-1
and the 96 h
LC50 values for M.philippinarum
were 0.023, 0.221, 2.876, 2.337 and 0.007 mg.l-1 in respective
metals. This study indicated that mercury was highly toxic to both C.cingulata and M.philippinarum. While lead was resistant metal to both marine
molluscs tested. Order of increasing toxicity of metals to C.cingulata was Hg > Cu > Zn> Cd > Pd and to M.philippinarum was Hg > Cu > Cd
> Zn > Pb. Safe level concentrations for all 5 metals were also calculated.
The LC50 values of the present study may be useful in deriving
marine water quality standards in the coastal waters of Gulf of Mannar.
