UCT QuEChERS Kits Cited in Cranberry Perfluoroalkyl Substances Study

Monday, October 09th, 2017

Perfluoroalkyl and polyfluoroalkyl substances (PFASs), in particular perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS), have been widely studied due to their persistence, distribution, toxicity and bio-accumulation in humans and the environment. These compounds can enter the environment through landfills (products containing stain repellents, food packaging), wastewater treatment plants (industry waste) and from the use of firefighting foams (aqueous film-forming foams [AFFFs]). In a recent study by Susan Genualdi et al., (FOOD ADDITIVES & CONTAMINANTS: PART A, 2017 https://doi.org/10.1080/19440049.2017.1361046 ), UCT’s QuEChERS kits (AOAC 2007.1, 6 g MgSO₄ with 1.5 g NaCl) and dispersive SPE (dSPE) sorbent (0.9 g MgSO₄, 0.3 g primary secondary amine [PSA], 0.15 g graphitized carbon black [GCB]) and were used for the extraction of PFAS in cranberries.
