However, PFAS are persistent organic pollutants (POPs) because of their environmental persistence, long-range transport, bioaccumulation potentials, and toxic effects on organisms. Settled dust can serve as environmental sink of organic pollutants including PFAS, and as exposure source of these substances in humans. In general, number of studies on PFAS in settled dust is relatively limited, especially in emerging and developing countries. In this review paper, analytical methods for PFAS in settled dust samples from international publications were gathered and evaluated, including information about sampling, sample preparation, extraction, clean-up, and quality assurance/quality control techniques. To determine trace levels of PFAS in dust matrix, liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods have been used with advantages as high selectivity and low detection limits. Further studies on analytical method development and application in monitoring and assessment of polution status and risk of PFAS in settled dust are critically necessary.}, issn = {2588-1140}, doi = {10.25073/2588-1140/vnunst.5686}, url = {https://js.vnu.edu.vn/NST/article/view/5686} }
