Rapid prediction of long-term rates of contaminant desorption from soils and sediments

Article Abstract:

The long-term desorption behavior of hydrophobic organic contaminants (HOCs) is predicted by heating water to high temperatures and measuring changes in desorption rates in soil and sediment samples over a period of a few hours. Penanthrene desorption rates are then plotted for activity in Lachine shale, Wagner soil, and Chelsea soil from Michigan at 25 degrees Celsius over a period of 640 days, matching the prediction.

Estimating the influence of forests on the overall fate of semivolatile organic compounds using a multimedia fate model

Article Abstract:

This study undertakes the evaluation of semivolatile organic compound uptake in forest canopies and how the terrestrial environment is affected by the forest's increase in the net atmospheric deposition. The study was conducted in Germany by the Department of Chemistry and Division of Physical Sciences, University of Toronto at Scarborough and the Baltic Sea Research Instititue of Rostock, Germany.
