The study focused on analysis of polybromobiphenyls (PBBs) and polybromodiphenyl ethers (PBDEs) congeners in office dust obtained in Pretoria, South Africa. Of the 32 congeners considered for identification, (BB-1, 2, 4, 10, 15, 26, 29, 30, 31, 38, 49, 80, 103, 153, 155, 209 and BDE-3, 15, 17, 28, 47, 66, 77, 85, 99, 100, 126, 138, 153, 154, 183, 209) only BB-2, 4, 30, 153, 209 and BDE-47, 66, 85, 99, 153 and 209 congeners were detected. The sum of PBBs concentration detected in office dust ranged from
⺠Five PBBs and six PBDEs congeners were detected in office dust with non-uniform distribution in Pretoria, South Africa. ⺠Statistical significant correlation between â5PBBs and â6PBDEs was obtained showing the similarity of pollution sources. ⺠No correlation was observed between the total number of electronic materials and concentration of BFRs detected. ⺠Substantially, lower concentrations of PBDEs detected in office dust compared to developed countries.
