Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity).
chemical changes under environmental conditions and the transformation products may be more toxic and carcinogenic than the parent molecule. Hence instead of detecting each chemical individually it is advisable to study the toxic effect of the effluents on various living organisms. Various techniques of toxicity and carcinogenicity measurements are discussed in this review. Remediation using
