DEFINITIVE STUDY OF THE DETERMINATION OF POLYBROMINATED DIBENZO-P-DIOXINS AND POLYBROMINATED DIBENZOFURANS IN DECABROMODIPHENYLOXIDE AND TETRABROMOBISPHENOL-A

Analytical methodology has been developed for the isomer specific anal ysis of fifteen 2,3,7,8-substituted polybrominated dibenzo-p-dioxins a nd polybrominated dibenzofurans in decabromodiphenyloxide and tetrabro mobisphenol-A. The procedures, developed by the Brominated Flame Retar dant Industry Panel, Triangle Laboratories, Incorporated, and Battelle , have been shown to afford accurate and precise measurements of the a nalytes in these matrices. Analysis of multiple DBDPO and TBBPA sample s, collected at random, show that none of the analytes are present in concentrations at or above specified limits of quantitation.
