Description 424-429
Present study consists the quantization of
specific metals-- Cr, Cd, Pb, Zn and Cu observed in the experimental bivalve,
Villorita species.  Bivalve specimens were
collected seasonally from the identified three hot spots of Vembanad Lake.
Soft tissue concentrations of metals are very sensitive in reflecting changes
in the ambient environment and hence important in assessing the environmental
quality. Concentrations of Zn in bivalves were fairly high compared to other
metals. All the stations showed a maximum concentration during premonsoon and
minimum during the other two seasons. Levels of Pb, Cu, Zn, Cd and Cr are
between 0-6.17mg/kg, 0-17.224mg/kg, 1.916-255.163mg/kg, 0.325-4.133mg/kg, and
0-15.233mg/kg respectively.
