PFAS are a persistent organic pollutant with known toxicity. There are numerous sources of origin for PFAS such as water/stain-resistant products, inks, cosmetics, and even fast-food wrappers. ALS has been testing for complex suites of PFAS analytes globally with accredited methods for decades. What started out as PFOS and PFOA has steadily grown into more than 40 compounds of interest as PFAS regulation and knowledge of their precursors and degradation processes increases.
