Technical Abstract: Aqueous phase partitioning is probably one of the more important processes involving pollutant transport in the environment. With the realization of the importance of air/water exchange at lake surfaces, this process has finally begun to receive the full recognition it is due. Even volatile losses from soil are intimately associated with soil moisture and involve air/water partitioning processes. Aqueous phase partitioning with rainfall has probably received the greatest attention. Use of terms such as wash-out coefficients and acid rain attest to the widespread acceptance of this mechanism. Considering the above, it should come as little surprise that pesticides and other pollutants are found in fog. Drs. Jim Seiber and Dwight Glotfelty were two of the first pioneering investigators to prove the existence of pollutants like agricultural pesticides can become concentrated in fogwater. Dioxins, furans, wood smoke markers, and many pesticides have now been shown to occur in fog and at many locations on th earth including the Arctic.
