Toxicity assessment of beta-cyfluthrin with impact on haematology of fish, Channa punctatus

Abstract

Âeta-cyfluthrin, a synthetic pyrethroid pesticide, is commonly used in agriculture for pest control and as household insecticide. It is relatively safe to mammals and birds but highly toxic to non-target aquatic organisms including fish. The 96- hour LC50 was determined using standard toxicity assessment tests. Alterations in haematological parameters were recorded after exposure to two sublethal concentrations of beta-cyfluthrin for a period of 15 and 30 days.The results showed a significant decrease in total erythrocyte count, haemoglobin concentration, haematocrit percentage and increase in total leucocyte count in exposed groups.The results of present study indicate a significant toxicological impact of beta-cyfluthrinon in Channa punctatus with marked alterations in haematological parameters.
