PBDEs were detected in all air and dust samples. The PBDE congener profile in both outdoor and indoor air samples from Thai e-waste storage facilities and homes was dominated by BDE-47 and 99, whilst the predominant BFRs in all dust samples from Thai e-waste storage facilities were BDE-209, BDE-208, BDE-207, BDE-206, BDE-197, BDE-183, BDE-99, BDE-47 and DBDPE. Furthermore, BDEs 99 and 47 were the most abundant congeners in all dust samples from Thai houses and cars and UK homes. Under realistic high-end scenarios of occupational exposure to BDE-99 via dust ingestion, workers in Thai e-waste storage facilities were exposed above a recently-published Health Based Limit Value for this congener. For non-occupational exposure, under a high-end exposure scenario, the exposure to BDE-99 of such Thai children via dust ingestion is either very close to or in exceedance of the HBLV. PBDE levels in most of the areas monitored within the same rooms were not statistically significantly different. Similarly, concentrations of PBDEs in the majority of rooms within the same houses were not statistically significantly different between rooms. Possible dilution of PBDE levels in dust with increasing dust loadings has been identified in a small number of rooms.
