Techniques to determine toxicity in industrial wastewater contaminated with dyes and pigments

Abstract

The deterioration of the environment is a matter of great concern today and has led to the development of research to remedy the harmful effects caused by man with his industrial activity overflowing. Water bodies are being affected by pollutant discharges from industries using dyes and pigments, as it is an alteration to aquatic systems by the interference in the passage of light and potentially toxic particles that have effects not only on the aquatic organisms but also possible indirect effects on human health. This research is developed to know and choose the most appropriate toxicity measurement techniques to evaluate the impact of these effluents loaded with dyes and pigments for their subsequent application to real residual water samples. A bibliographic review of different techniques for aquatic toxicity evaluation is carried out and the importance of the application of these tests in the evaluation of the advantages, and the efficiency of the color removal treatments is emphasized.
