Abstract
The volatilization of organic environmental contaminants from water bodies to the
atmosphere was investigated. The general aim was to elucidate the factors that control
the volatilization process and develop predictive methods for calculating volatilization
rates for various compounds from rivers, lakes and other water bodies under
various conditions of temperature and wind speed. The report contains both theoretical and experimental studies and a comprehensive
review of the equilibrium physical chemistry and thermodynamics of systems involving
hydrophobic organic solutes and water. A result of the thermodynamic analysis is the
development of the fugacity approach for calculating multi-phase equilibria applicable
to environmental partitioning. The approach can also be applied to calculating multiresistance
transfer as may occur in lakes. Correlations are developed for predicting
or checking consistency of data for aqueous solubility, vapor pressure, Henry's law
constant and octanol-water partition coefficient.
