Molecular weight and adsorption characteristics. Correlation was found for both soils between the logarithm to the distribution coefficient (K OC, kg/l) and the molecular weight of the individual PFCs. The soils used were sampled at Jynnevad (plus sign, sandy soil, linear fit green line, y = 0.0275x − R 2 = 0.9928) and Sj. Odde (filled circle clay soil, polynomial fit blue line, \( y = 1E - 04{x^2} - 0.0593x + 7.3 \) R2 = 0.9956)
