QUANTITATIVE DETERMINATION OF PERFLUOROALKYL SUBSTANCES (PFAS) IN SOIL, WATER, AND HOME GARDEN PRODUCE
Huset, C.A. and K.M. Barry.
MethodsX 5:697-704(2018)

Simple and efficient analytical methods were used to measure perfluoroalkyl substances (PFASs) in water, soil, and produce from home gardens in Minnesota. PFASs in water were analyzed via direct injection. PFASs were extracted from homogenized soil using sonication and from produce using dispersive solid-phase extraction. Isotope dilution was used for quantitation in all methods. The method performance parameters and quality control measures described are applicable for PFASs ranging from C4-C8. The produce method was used on a wide variety of produce. This paper is available in full text at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6039355/.
