Environmental contamination is aninsistent concern affecting human health and the ecosystem. Wastewater, containing heavy metals from industrial activities, significantly contributes to escalating water pollution. These metals can bioaccumulate in food chains, posing health risks even at low concentrations. Copper (Cu), an essential micronutrient, becomes toxic at high levels. Activities like mining and fungicide use have led to Copper contamination in soil, water, and sediment beyond safe levels. Copper widely used in industries, demands restraint of heavy metal ion release into wastewater for ecosystem ultrafiltration, membrane filtration, nanofiltration, and reverse osmosis, combat heavy metal pollution, with emphasis on copper.Physical and chemical approaches are efficient, large-scale feasibility may have drawbackssuch as they are costly, result in the production of sludge. In contrast, bioremediation, microbial intervention offers eco-friendly solutions for copper-contaminated soil. Bacteria and fungi facilitate these bioremediation avenues as cost-effective alternatives. This review article emphasizes on physical, chemical, and biological methods for removal of copper from the wastewater as well asdetailing microorganism's mechanisms to mobilize or immobilize copper in wastewater and soil.
环境污染是一个持续存在的问题,影响着人类健康和生态系统。工业活动产生的重金属废水是水污染加剧的主要原因之一。这些金属可以在食物链中生物累积,即使在低浓度下也会对健康造成风险。铜(Cu)是一种必需的微量元素,但在高浓度下会变得有毒。采矿和使用杀真菌剂等活动导致土壤、水和沉积物中的铜污染超过安全水平。铜在工业中广泛应用,需要控制重金属离子向废水的释放,以进行超滤、膜过滤、纳滤和反渗透等生态系统过滤,从而应对重金属污染,重点是铜。物理和化学方法是有效的,但大规模实施可能存在成本高、产生污泥等缺点。相比之下,生物修复,即微生物干预,为受污染的土壤提供了环保的解决方案。细菌和真菌作为具有成本效益的替代方法,促进了这些生物修复途径。本文强调了从废水中去除铜的物理、化学和生物方法,并详细介绍了微生物在废水中和土壤中移动或固定铜的机制。
