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.

N,N-二乙基-3-甲苯酰胺 (DEET) 降解的最新进展——一种新兴的环境污染物：综述

N , N-二乙基-3-甲苯酰胺 (DEET) 是一种常用的驱虫剂，它是水中的有机化学污染物，被认为是世界范围内观察到的一种新兴污染物。它通过污水废物排放到环境中。已使用各种方法来降解避蚊胺，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，关于通过部署纳米粒子降解避蚊胺的研究较少。因此，生物降解和基于纳米技术的方法可以成为修复环境中避蚊胺的潜在解决方案。本综述试图分析避蚊胺进入大气的途径及其对环境健康的影响，并探索物理、化学和生物的降解方法。此外，它还重点关注用于避蚊胺生物降解的各种方法，包括其环境后果。未来需要研究应用生物方法降解避蚊胺。通过物理、化学和微生物基因组学的应用，探索新的有效微生物菌株的生物降解代谢途径；分子生物学;基因工程;和基因组测序方法。
