Some of the main processes that remove, immobilize or detoxify heavy metals and radionuclides in the natural environment result from microbial activities. These activities can be harnessed to clean up toxic metal wastes before they enter the wider environment. To date, the most successful biotechnological processes utilize biosorption and bioprecipitation, but other processes such as binding by specific macromolecules may have future potential. Technologies using these processes are currently used to control pollution from diverse sources, including smelters and mine workings.
在自然环境中，去除、固定或解毒重金属和放射性核素的一些主要过程源于微生物活动。这些活动可用于在有毒金属废物进入更广泛环境之前对其进行清理。迄今为止，最成功的生物技术过程利用生物吸附和生物沉淀，但其他过程，如特定大分子的结合，可能具有未来潜力。目前，使用这些过程的技术被用于控制来自各种来源的污染，包括冶炼厂和矿山作业。
