Abstract
- Numerous poly- and perfluoroalkyl substances (PFAS) have been manufactured and distributed on the world market. Research on PFAS has highlighted their global distribution and impacts on ecosystems and human health. Following regulations and public concern, PFAS production has shifted toward novel molecules in recent years. New classes of PFAS have been identified in the environment and are gaining worldwide attention. The development of an efficient strategy for identification and quantification of emerging PFAS is essential for risk assessment. This review presents and discusses the most recent analytical method development for PFAS in air, water, abiotic solid matrices and biological matrices, and addresses non-target approaches. Various methods are covered including sampling, pre-treatment (enrichment, extraction and clean-up) and instrumental analysis, and their applications, advantages, shortcomings and future needs are explored. • We discuss recent trends in analytical methods for PFAS in various matrices. • PFAS in air, water, abiotic solids and biological samples are investigated. • Our review covers various methods including sampling, pretreatment and measurement. • We review current analytical techniques and their performance to help future PFAS research.
