Toxicity Analysis of Dyes

Abstract

In the textile sector, synthetic dyes are crucial. However, dyes pose a serious threat to all organisms because of their toxicity. Environmental concerns have grown over the non-selective and excessive usage of these dyestuffs. These colours have the potential to be harmful in terms of behaviour, biology, chemistry, physicality, and radiation. The toxicity of the dyes can be classified as acute (short-term effect) or chronic (long-term damage). In order to establish criteria for the regulation of dyes when they come into contact with humans and other living things, toxicity analyses of dyes are therefore required. In a toxicology study, the reaction of an organism to a specific dye at different concentrations is compared to the reaction of the same organisms not exposed to the dye. The toxic effects of an experimental substance are revealed by toxicity testing on numerous biological systems. The producers utilize this evaluation to determine the dye's toxicity and whether it has carcinogenic or non-carcinogenic effects.

Keywords: Acute toxicity, Chronic toxicity, Dose descriptors, Dose-response relationship, Synthetic dyes, Sub-acute toxicity.
