Persistence of Chlorinated Dioxins and Furans in the Soil Environment
The persistence of di- to octachloro dioxins and furans has been investigated in various soil environments. Over a 15-month period, measurable degradation - i.e., that leading to loss greater than the precision level of the analytical methodology - was found to occur only in the case of di- and trichloro congeners. The degradation of tetra through octachloro congeners was minimal. In the absence of a carrier co-pollutant, the mobility rates of chlorinated dioxins and furans are not significantly affected by the presence of co-pollutants such as pentachlorophenol and creosote components which are commonly present at wood treatment sites.
