Abstract
Numerous technical studies have
demonstrated that vapor phase air-water exchange of a number of toxicants including elemental mercury display a diel cycle. Specifically, daytime rates of air-water exchange can exceed nighttime values by 33 to 300%
(e.g. see references cited in Loux, 2000 and Loux, 2001).
Loux (2001) illustrated that while diel water column elemental mercury concentration cycles may tend to be the dominant factor in observed diel cycles in elemental
mercury air-water exchange rates, the effect of diel cycles in temperature disequilibrium between the atmosphere and underlying waters also may be significant.
