Comment on "Visualising the Equilibrium Distribution and Mobility of Organic Contaminants in Soil Using the Chemical Partitioning Space [Wong and Wania, J. Environ. Monit., 2011, 13, 1569-1578]"

Authors: Sierra Rayne

In their article, Wong and Wania [J. Environ. Monit., 2011, 13, 1569-1578] claim to estimate the partitioning properties (air-water partition coefficients and soil organic carbon-water partition coefficients) of twenty neutral organic chemicals using poly-parameter linear free energy relationships. Five of the 20 compounds in this study have ionizable functional groups with environmentally relevant pKa values, meaning the corresponding partitioning properties are highly pH dependent, thereby rendering the modeling approach applied by these authors subject to a fatal conceptual and practical flaw.
