ABSTRACT
Toxicity can be categorized as acute and chronic on the basis of the number of exposures to poison and time taken for developing toxic symptoms. Exposure is of the short duration in the case of acute toxicity and results can be observed within a short period of time. Acute toxicity can be defined as a chemical’s or pesticide’s capacity to bring systemic damage as a consequence of one-time exposure to a fairly large amount of the chemical. Acute toxicity tests are typically employed for determining the effects of exposure to high amounts of chemicals. The acute toxicity test can estimate the concentration of the medium required to kill 50 per cent of test animals. In the chronic toxicity, adverse results are observed after a considerably long time. On the contrary, the chronic toxicity tests are typical long-term tests conducted to find the effects of exposure to comparatively less toxic concentrations.
