Abstract

Tannery effluents are containing harmful inorganic chemical substances such as chlorides, sulphides, chromium, lead, mercury, nitrogenous compounds and tannins as well as trace organic chemicals. The increased use of synthetic chemicals like dyes and finishing agents are mainly responsible for these pollutants. In the last few decades, pollution from tanneries at the leading industrial site in Dhaka discharged into the Buriganga River. These substances are commonly toxic and persistent, posing health and environmental risks. In this article, we discussed the deterioration of environmental quality with tannery effluents. The health impacts, water quality, damaging ecology, and threatening people's livelihoods are directly and indirectly related to exposure to hazardous wastes, including carcinogenic effects, reproductive system damage, respiratory system effects and central nervous system effects. The goal of this review was to evaluate the environmental quality in the Hazaribagh tannery industrial area. This study discusses many remediation approaches that help improve environmental quality. These findings recommend monitoring and cleaning up tannery effluent simultaneously. This review examined heavy metal contamination, exposure toxicity, research gaps, existing regulations, and long-term remediation methods in Hazaribagh to enhance environmental quality.
