A method for the analysis of airborne (semi-)volatile polyfluorinated alkyl substances (PFASs) was optimized to avoid solvent-induced response enhancements as observed using ethyl acetate as extraction solvent (recoveries up to 300%, likely due to acetic acid as impurity). Of nine solvents tested, only the use of acetone, dichloromethane, methyl tert-butyl ether, and acetone:petroleum ether (1:1, v/v) resulted in recoveries below 100% and acetone:methyl tert-butyl ether (1:1, v/v) was chosen as… CONTINUE READING
