摘要

2,4-二硝基苯甲醚 (DNAN)、3-硝基-1,2,4-三唑-5-酮 (NTO) 和硝基胍 (NQ) 等不敏感弹药化合物 (IMC) 因其较高的引爆温度和较强的抗机械冲击能力而正在取代传统炸药,使其在处理和储存方面更加安全。IMC 可通过军事训练场中未引爆残留物的溶解或 IMC 制造废水的排放污染环境。鉴于 IMC 或其转化产物的毒性,有时还具有致癌性,制定补救策略已成为当务之急。生物修复为处理 IMC 提供了一种具有成本效益的方法,有可能将有害污染物转化为无害产品。近年来,针对 IMCs 生物修复的各种策略的研究激增。因此,对该领域的研究成果进行综述并指导未来的研究势在必行。本研究旨在为 IMCs 及其转化产物的微生物修复提供第一份综合指南。它首先解释了 IMC 的厌氧生物转化和好氧矿化所涉及的机制。然后探讨了用于处理单个 IMC 及其混合物的不同类型的生物反应器系统。最后,它提供了潜在的生物修复方法,用于处理弹药制造设施产生的废水以及受 IMC 污染的地下水和土壤。重点是支持科学家、工程顾问和场地修复管理人员开发和优化针对 IMCs 污染的有效微生物修复策略。

Microbial remediation of insensitive munitions compounds and their transformation products: from biodegradation mechanisms to engineered strategies

Insensitive munitions compounds (IMCs), such as 2,4-dinitroanisole (DNAN), 3-nitro-1,2,4-triazol-5-one (NTO) and nitroguanidine (NQ), are replacing conventional explosives due to their higher detonation temperatures and greater resistance to mechanical shocks, making them safer for handling and storage. IMCs can contaminate the environment through the dissolution of undetonated residues in military training ranges or the discharge of wastewater from IMCs manufacturing. Developing remediation strategies has become imperative, given the toxicity and, in some cases, carcinogenicity of IMCs or their transformation products. Bioremediation offers a cost-effective method to treat IMCs, potentially converting hazardous contaminants into harmless products. Recent years have seen a surge in research focused on various strategies for IMCs bioremediation. Thus, a review becomes imperative to consolidate findings and guide future research in this field. This work aims to provide the first comprehensive guidelines for the microbial remediation of IMCs and their transformation products. It starts by explaining the mechanisms involved in anaerobic biotransformation and aerobic mineralization of IMCs. It then explores different types of bioreactor systems used for treating both individual IMCs and their mixtures. Finally, it provides potential bioremediation approaches for handling wastewater from munitions manufacturing facilities and addressing groundwater and soil contaminated by IMCs. The focus is to support scientists, engineering consultants, and site remediation managers in developing and optimizing effective microbial remediation strategies for IMCs contamination.
