Chronic exposure of fresh water bivalve, Parreysia corrugata to the chelating agents CaNa2- EDTA and L- cysteine adversely affect the calcium and potassium content of different body parts. Parreysia corrugata were exposed to 40 mg/L concentrations of CaNa2- EDTA and 50 mg/L concentration of L- cysteine for 8 and 15 days. There was decrease in calcium and potassium content of whole tissues and mantle due to Ca Na2 EDTA and L-cysteine treatment. The depletion in potassium content is less than that of calcium in whole tissue as well as mantle of the P. corrugata. The depletion in the calcium and potassium is possibly, due to formation and elimination of their complexes with the chelators Ca Na2 EDTA and L- cysteine.

Parreysia corrugata, CaNa2- EDTA, L- cysteine, chelating agent, calcium, potassium.
