Measurements of the Photolytic Breakdown of Decabromodiphenyl Ether in Plastics
Marc R. Nyden, Rick D. Davis, Christopher C. White, H M. Stapleton, Nathan G. Dodder
In this talk, we report the product distributions and decomposition rates of DecaBDE when it is incapsulated in a common plastic, high impact polystyrene, and irradiated under controlled conditions using a calibrated source. The objective is to gain additional insights into the mechanisms by which DecaBDE can migrate from plastics into the environment either as the intact molecule, or after undergoing photolytic transformation to produce other PBDEs and/or dibenzofurans (PBDFs). This information is critical to efforts directed at identifying sources of these compounds and estimating their contributions to the environmental problem.
