Water pollution due to effluents from textile dyeing industry is a cause of serious concern. The techniques for detection of dyes are cost intensive and futile because the dyes undergo 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 physical, chemical and biological methods has also been critically reviewed.

Keywords:  dyes, pollution, toxicity, carcinogenicity, decolourisation.
