文摘
- •
Anisotropic PE exchange kinetics is observed for PCBs in quiescent sediment.
- •
A novel non-equilibrium passive sampling method is developed.
- •
PEs with multiple thicknesses are deployed in non-eq. mode to estimate PCB Cfree.
- •
The new method reasonably estimates PCB Cfree in sediment pore-water.
