Adsorption (plus sign) and desorption (filled circle) on soil as exemplified by isotherms. The adsorption of the PFC on the solid phase (C s, μg/kg) is plotted against the concentration in the aqueous phase (C aq, μg/l). Correlation coefficients and other details are given in Table 4. a PFHpA (Jynnevad, soil-to-water ratio 12:25), b PFOA (Jynnevad, soil-to-water ratio 12:25), c PFNA (Sj. Odde, soil-to-water ratio 3:14), d PFDA (Sj. Odde, soil-to-water ratio 3:14), e PFBS (Jynnevad, soil-to-water ratio 12:25), f PFOS (Sj. Odde, soil-to-water ratio 3:14)
