This review summarizes the recent papers published about the microbial communities under the conditions of persistent heavy metals around the world. Many microbial communities' study has demonstrated intense changes in the community composition, and microbial diversity caused by heavy metals, environmental pollution as well as adaptation processes allowing survival of microbes in metal-polluted ecosystems. The effect of heavy metals such as Cu, Pb, Hg, Ni, Cd, Zn, and As on soil microbial communities in mediated soil are reviewed. The different sensitivity measurement, toxicity of metals, relative toxicity is discussed. In recent years, industrial activities have a significant influence on the environment. Especially, heavy metals such as Hg, Cr, Pb, Mn, and As, have induced seriously affected the soil microbial communities, cause diseases and even death of organisms through contaminated soils, although heavy metals in trace amounts are beneficial even significant to organisms. The effect of heavy metals on soil microbial communities is still poorly understood. That how microbial communities respond to environmental changes is a key issue in ecology. In the future further work needed to understand the microbial community under persistent heavy metals, their effects, how to reduce and decrease the microbial diversity, and resistance of specific bacterial species to heavy metals.
本综述总结了世界各地关于在持续存在重金属条件下的微生物群落的最新研究论文。许多微生物群落的研究表明，重金属、环境污染以及适应过程会导致群落组成和微生物多样性发生强烈变化，从而使微生物能够在金属污染的生态系统中生存。本文综述了 Cu、Pb、Hg、Ni、Cd、Zn 和 As 等重金属对介导土壤中土壤微生物群落的影响。讨论了不同的敏感性测量、金属的毒性和相对毒性。近年来，工业活动对环境有重大影响。特别是 Hg、Cr、Pb、Mn 和 As 等重金属通过污染土壤严重影响了土壤微生物群落，导致生物患病甚至死亡，尽管微量的重金属对生物是有益甚至是重要的。重金属对土壤微生物群落的影响仍知之甚少。微生物群落如何响应环境变化是生态学中的一个关键问题。未来需要进一步研究在持续存在重金属的情况下的微生物群落，了解它们的作用、如何减少和降低微生物多样性以及特定细菌物种对重金属的抗性。
