Environmental and Toxicological Implications of Dyes: A Mini Review
Abstract: Synthetic dyes are extensively used in industries – such as textiles, leather, paper, and food processing – due to their vibrant colors and high chemical stability. However, the large-scale release of dye-containing wastewater has become a significant environmental and health concern. Owing to their complex chemical structures, most synthetic dyes are highly resistant to biodegradation, resulting in their long-term persistence in aquatic and terrestrial ecosystems. Their accumulation in water bodies …
