Environmental Mobility of Dioxins

Source

A model has been developed to describe the vapor phase transport of low volatility organic chemicals in a soil column. The mathematical model finds the rate of vapor transport by solving the dynamic material and energy balance around a soil column. The model is used to make predictions on the transport of 2,3,7,8 tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) at the Times Beach, MO site. The model predicts that 70% of the initial dioxin mass vaporized in the first year after being sprayed onto the roads at Times Beach. In addition the model predicts that most of the transport occurs during the summer months.
