POLYBROMINATED DIPHENYL ETHERS (PBDEs) IN AIR AND DUST FROM ELECTRONIC WASTE STORAGE FACILITIES AND HOUSES IN THAILAND:IMPLICATIONS FOR HUMAN EXPOSURE
This study is the first report of PBDE concentrations in indoor/outdoor air (using PUF disk passive air samplers) and dust samples collected from 5 electronic waste storage facilities and 33 homes in various locations across Thailand. Ten PBDE congeners present predominantly in the Penta-BDE formulation (BDE 17, 28, 47, 49, 66, 85, 99, 100, 153 and 154) were measured in a total of 18 air and 78 dust samples. Atmospheric concentrations of ΣPBDEs in outdoor air in the vicinity of electronic waste storage facilities ranged from 8 to 150 pg m-3. Indoor air concentrations ranged from 46 to 350 pg m-3, with highest concentrations found in a computer and printer waste storage room at a waste storage facility. ∑PBDE concentrations in domestic indoor air ranged from 23 to 72 pg m-3. The predominant congeners in both outdoor and indoor air samples were BDE 47 and 99. Concentrations in dust from electronic waste storage plants and houses were 36-12000 and 0.55-260 ng ∑ PBDE g-1 respectively, with the highest levels found in a room used to house computers and printers at a waste storage facility. The congener profile in all dust samples was dominated by BDE 99 and 47. While the concentrations in Thai domestic indoor air and dust appear at the low end of those reported elsewhere in the world, these data may still indicate indoor environments to be important sources of occupational and non-occupational exposure of the Thai population to PBDEs.
