Acute Toxicity Testing of Pyrethroid Pesticide to Freshwater Snail (Angulyagra polyzonata)

Abstract

    Pyrethroid pesticide toxicity testing on freshwater snail (Angulyagra polyzonata) was done in laboratory scale by artificial exposure to Cypermethrin and Deltamethrin for 96 hours period. The results showed that Angulyagra polyzonata was more sensitive to Deltamethrin than Cypermethrin. The recovery of freshwater snails was descending when exposed to pyrethroids for 48 hours and then released into water within 48 hours. Bioaccumulation fator (BCF) with Cypermethrin was 0.88 and 26.29 with exposure time of one day and one month, respectively.
