| 近年来，生物炭在污染土壤修复中的研究与应用受到广泛关注，且已被证实对于修复土壤重金属及有机污染具有显著的效果。生物炭可以改善土壤性质，影响土壤微生物群落，实现生物炭介导的微生物土壤污染修复。本文综述了生物炭对微生物的积极作用，包括提供额外生存环境、提供营养物质和改善原有栖息地[土壤团聚性、pH、阳离子交换能力（CEC）和酶活性]。这些影响将导致微生物丰度、活性和群落结构的变化。然而，生物炭所携带的可能威胁微生物群落的有毒物质也不应被忽视，如多环芳烃、呋喃等；同时生物炭在高温热解过程中产生的持久性自由基也会对微生物产生毒性。本文还讨论了生物炭介导的微生物修复技术在去除土壤污染物方面的应用现状，最后对生物炭-微生物交互作用在土壤污染修复中的研究方向提出了展望。 |
| 英文摘要: |
| In recent years, the research and application of biochars（BCs）in the remediation of contaminated soil have been a strong and widespread focus. It has been demonstrated to have remarkable impacts on the remediation of heavy metal and organic contamination in soil. BCs can improve soil properties, influence soil microbial communities, and achieve biochar mediated microbial remediation of contaminated soil. This review systematically analyzed the positive effects of BCs on microorganisms, including providing additional living environments, nutrients and improving native habitats including soil aggregates, pH, cation exchange capacity（CEC）and enzyme activity. This led to changes in microbial abundance, activity, and community structure. However, it was important not to neglect the potential risks that BCs might have on the microbial community from that toxic substances carried, such as polycyclic aromatic hydrocarbons（PAHs）and furan. Persistent free radicals（PFRs）produced by BCs during high temperature pyrolysis were also likely to be toxic to microorganisms. Moreover, the applications of biochar-mediated microbial remediation in contaminated soil were also discussed and reviewed. The review was concluded with an outlook on the direction of biochar–microbial interactions in contaminated soil remediation, which can help us to select and modify BCs and integrate them more effectively with microorganisms in line with the target applications. |
