With growing production and application, the presence of carbon nanomaterials (CNMs) in soil contaminated by organic pollutants (OPs) is inevitable and widespread because of their unintentional discharges. The strong sorption of OPs by CNMs can alter the bioavailability to microorganisms, which is important for their biodegradation. Meanwhile, the potential ecotoxicity of CNMs to soil microorganisms can also significantly affect biodegradation and bioremediation of OPs. To date, most studies have mainly focused on the impact of CNMs on the microbial availability of OPs and their degradation; the knowledge regarding the microbial response to CNMs and its impact on the biodegradation of OPs and the associated physiological mechanisms is very limited. This paper presents an overview on how CNMs may affect the microbial degradation of OPs (in soil) based on the effects of OP–CNM interactions on the microbial availability of OPs and those of CNMs on the activity and degradation capability of microorganisms at both cellular and community levels. Furthermore, that the ubiquitous dissolved organic matter (DOM) may influence the sorption and immobilization of OPs by CNMs and ecotoxicity of CNMs and the associated impacts on the biodegradation of OPs in addition to the underlying mechanisms regulating these processes are also investigated.

有机污染物与碳纳米材料之间的相互作用及其对土壤微生物有效性和降解的影响：综述

随着生产和应用的不断增长，由于有机污染物的无意排放，在土壤中被有机污染物（OPs）污染的碳纳米材料（CNMs）的存在是不可避免和广泛的。CNM对OP的强烈吸附可以改变微生物的生物利用度，这对于微生物的生物降解很重要。同时，CNM对土壤微生物的潜在生态毒性也可以显着影响OP的生物降解和生物修复。迄今为止，大多数研究主要集中在CNM对OP的微生物有效性及其降解的影响。关于微生物对CNM的反应及其对OP的生物降解和相关生理机制的影响的知识非常有限。本文基于OP–CNM相互作用对OP的微生物有效性的影响以及CNM对细胞和细菌的活性和降解能力的影响，概述了CNMs如何影响OP（在土壤中）的微生物降解。社区级别。此外，普遍存在的溶解有机物（DOM）可能会影响CNM对OPs的吸附和固定以及CNM的生态毒性，并且除了调节这些过程的潜在机制外，还研究了其对OPs生物降解的相关影响。
