Air-Water-Microlayer Equilibrium

SPMDs are powerful tools to assess the degree of equilibrium between environmental compartments. Booij and van Drooge (2001) exposed SPMDs to water 

The authors also assessed the degree of equihbrium between atmospheric and aqueous PCBs and hexachlorobenzene (HCB). The ratio of absorbed amounts for SPMDs exposed to air (Af ) and water (N ) is given by
