BIOREMEDIATION OF MERCURY CONTAMINATION: A REVIEW

Mercury (Hg) pollution has become one of the most important environmental problems because of its high toxicity, wide range of pollution and high risk of ecological health. The anthropogenic sources of mercury pollution mainly include fossil fuel combustion, mineral exploitation and processing, waste incineration and production and use of mercury related products. Bioremediation has a good prospective application in the treatment and remediation of mercury contamination due to their advantages of low cost, easy operation and ecological friendliness. This paper reviews the main sources and current situation of mercury pollution in the environment, and summarizes the application and mechanism of eco-friendly technology based on the action of plants and microorganisms in the remediation of mercury polluted soil and water. Furthermore, the relevant issues that should be further studied and practiced in bioremediation of mercury pollution have also been proposed. The main purpose of this paper is to provide a scientific reference for bioremediation of mercury pollution.
