文摘
- •
Polyurethane foam-air partition coefficients (KPA) are needed to estimate passive air sampling rates.
- •
KPA were determined for two anthropogenic and two natural SVOCs in air sampling experiments over the Baltic Sea.
- •
KPA predicted from octanol-air partitioning or polyparameter free energy models varied by factors of 3 to over 30.
- •
Such variability provides an incentive for further measurements and modeling with other SVOCs.
