ESTIMATION OF TOXICITY EVALUATION (LD50) OF LAMBDA CYHALOTHRIN, A SYNTHETIC PESTICIDE ON ALBINO MICE *M.Suseela

Pesticides are designed to control pests. They all are toxic to some level; otherwise they would not kill pests. They can also be toxic to non-target organisms such as plants, animals or humans. Exposure to a sufficient amount of almost any pesticide can affect a person—either through illness, eye exposure or skin sensitivity. Excess of any compound will be harmful to life and consider leader toxicity studies Pesticides are use for welfare of human beings but by the time, they will challenge us by showing their toxicity. Pesticide pollution brings about sudden & drastic changes. The biological effects of pesticides and their mode of action are obtained from toxicity studies. The present study aim to find out the short term exposure effect of Lambda cyhalothrin on Albino mice with various doses 8,12,16,20,24,28,36,40,48,52 mg/kg bw respectively. By the study of toxicity evaluation by the Probit Analysis method of Finney, LD50 of Lambda cyhalothrin has been found to be 24mg/kg bw with the exposure period of 48hrs.
