Removal of Azo Dyes from Aqueous Effluent Using Bio-Based Activated Carbons: Toxicity Aspects and Environmental Impact

This review discusses the toxic effects of azo dyes, widely used in textile manufacturing, and methods for removing them from wastewater using activated carbon. While not directly about microplastics, the research connects to microplastic concerns because synthetic textile fibers that shed as microplastics often contain residual azo dyes. When these microfibers enter waterways, they can release dye chemicals that are known to be carcinogenic and mutagenic, adding a chemical dimension to microplastic pollution.
