The per/polyfluoroalkyl substances (PFAS) are growing contaminants which are extremely difficult to get degraded naturally. PFAS have been produced for nearly a century using electrochemical flourination and more relomerization processes. High chemical resistance, hydrophobicity, lipophobicity, heat resistace, extremly low friction coefficient make this class of chemicals invaluable for many applications. These same properties useful unfortunately make them 'forever chemicals' once released into the envrironment. This review focuses on the production and applications of PFAs, determining the concentration of PFAs in environmental and biological matrices and their efficient degradation. Various methods of detection of PFAS have been developed but insitu methods of detction are still in the early stages of development. Current chemical and biological remediation technologies are expensive/not effective and thus new remediation technolgies must be developed. It is imperative to focus on methods for detection of the short chain PFAS with their projected increased use.
全氟/多氟烷基物质（PFAS）是日益增多的污染物，极难自然降解。PFAS已经通过电化学氟化和更多的重排工艺生产了近一个世纪。高化学抗性、疏水性、疏脂性、耐热性以及极低的摩擦系数使这类化学品在许多应用中具有极高价值。不幸的是，这些有用的特性一旦释放到环境中，就使它们成为“永久性化学品”。本综述重点关注PFAS的生产和应用、测定环境和生物基质中PFAS的浓度及其有效降解。已经开发了各种检测PFAS的方法，但现场检测方法仍处于开发初期。目前的化学和生物修复技术昂贵且无效，因此必须开发新的修复技术。随着短链PFAS预计使用量的增加，关注其检测方法势在必行。
