ABSTRACT
Bioaccumulation studies of fenvalerate were conducted on Indian bullfrog Haplobatrachus tigrinus (Daudin) after exposure to sublethal intraperitoneal dose of technical grade fenvalerate (1/3 LD50 i.e. 116.66 microg/kg body weight) at 3, 6, 12, 24, 48 and 72 hours schedule. The tissues viz., muscle, liver, kidney, testis, brain, and whole body accumulation was analysed for residue estimations. In all the tissues, analysed maximum residue was recovered in the initial stages of exposure (3 and 6 hours). However, in brain the residues remained up to 72 hours. In the whole body, analysis after 3 hours of exposure 78.65% residue was recovered and by the time 72 hours passed only, 9.4% residue was recovered. The decline in residue levels along with the period of exposure indicates the fast acting nature of fenvalerate and metabolites.
