LEVELS OF POLYCHLORINATED BIPHENYLS, BROMINATED FLAME RETARDANTS AND DIOXIN-LIKE ACTIVITES ASSOCIATED WITH E-WASTE RECYCLING IN VIETNAMESE HOUSE DUST
PCBs, brominated flame retardants (BFRs) and dioxin-like activities were investigated in house dust collected from two Vietnamese e-waste recycling sites (EWRS) and an urban control site. Levels of PBDEs and HBCDs in the EWRS were 110–10000 and 5.4–400 ng/g, respectively; median levels were higher than in the urban control site by a factor of 3 to 7 for both groups of contaminants. PCB levels, 5–320 ng/g, were not statistically higher than control levels but higher percentages of tri- and tetra-CBs were observed. Dioxin-like activities ranged from 370 to 1000 pg CALUX-TEQ/g with the median level (500 pg CALUX-TEQ/g) higher than the median control level by a factor of 2.5. These results indicate that e-waste recycling activities play a role as significant sources of BFRs and dioxin-like compounds and suggest dust ingestion as an important intake pathway for these contaminants particularly in case of e-waste recyclers.
