Living beings have been devastated by environmental pollution, which has reached its peak. The disastrous pollution of the environment is in large part due to industrial wastes containing toxic pollutants. The widespread use of chromium (Cr (III)/Cr (VI)) in industries, especially tanneries, makes it one of the most dangerous environmental pollutants. Chromium pollution is widespread due to ineffective treatment methods. Bioremediation of chromium (Cr) using bacteria is very thoughtful due to its eco-friendly and cost-effective outcome. In order to counter chromium toxicity, bacteria have numerous mechanisms, such as the ability to absorb, reduce, efflux, or accumulate the metal. In this review article, we focused on chromium toxicity on human and environmental health as well as its bioremediation mechanism.
生物深受环境污染之害，其严重程度已达顶峰。环境灾难性的污染在很大程度上是由于工业废物中含有有毒污染物。铬（Cr(III)/Cr(VI)）在工业中的广泛应用，特别是制革业，使其成为最危险的环境污染物之一。由于处理方法无效，铬污染广泛存在。利用细菌进行铬（Cr）的生物修复是非常有意义的，因为它具有环保和经济有效的特点。为了应对铬的毒性，细菌有许多机制，如吸收、还原、外排或积累金属的能力。在这篇综述文章中，我们重点介绍了铬对人类和环境健康的毒性及其生物修复机制。
