Abstract：
N,N-Diethyl-3-toluamide (DEET) is a commonly used insect repellent, which acts as an organic chemical contaminant in water and considered as an emerging contaminant which has been observed worldwide. It gets discharged into the environment through sewage waste. The various methods have been used to degrade DEET, such as UV based, ozonation, photocatalytic degradation, and biodegradation (based on the metabolic activity of fungi and bacteria). However, less research has been done on the degradation of DEET by deploying nanoparticles. Therefore, biodegradation and nanotechnology-based methods can be the potential solution to remediate DEET from the environment. This review is an attempt to analyze the routes of entry of DEET into the atmosphere and its environmental health consequences and to explore physical, chemical, and biological methods of degradation. Furthermore, it focuses on the various methods used for the biodegradation of the DEET, including their environmental consequences. Future research is needed with the application of biological methods for the degradation of DEET. Metabolic pathway for biodegradation was explored for the new potent microbial strains by the application of physical, chemical, and microbial genomics; molecular biology; genetic engineering; and genome sequencing methods.
摘要：
N,N-二乙基-3-甲苯胺(DEET)是一种常用的驱虫剂,它是水中的有机化学污染物，被认为是全球范围内观察到的新兴污染物。它通过污水废物排放到环境中。各种方法已被用于降解DEET，例如基于紫外线，臭氧化,光催化降解，和生物降解（基于真菌和细菌的代谢活性）。然而,关于部署纳米粒子降解DEET的研究较少。因此,生物降解和基于纳米技术的方法可能是从环境中修复DEET的潜在解决方案。本文试图分析DEET进入大气的途径及其对环境健康的影响,化学,和生物降解方法。此外，它着重于用于DEET生物降解的各种方法，包括其环境后果。需要应用生物方法降解DEET的未来研究。通过物理应用，探索了新的有效微生物菌株的生物降解代谢途径，化学,和微生物基因组学;分子生物学;基因工程;和基因组测序方法。
