Exposure assessment of polybrominated diphenyl ether for electronics recycling workers in Taiwan
Occupational exposure to PBDEs have been reported in electronic recycling plant. To achieve a sustainable society, waste recycling should be conducted particularly for electronic devices. This study aims to assess the PBDEs exposure levels for electronics recycling workers in Taiwan. Forty-seven participants were divided into four groups–administration workers (reference group), supervisors, technicians, and dismantling and sorting workers. Serum concentrations of eight PBDEs congeners were determined by GC/MS. The concentrations of PBDEs were the highest in the blood of sorting workers (geometric mean, 102.33 ng/g lipid), followed by the supervisors, technicians, and the reference group. Of the eight PBDEs congeners, BDE-100 was most commonly detected while BDE-183 was not detected in any of the subjects. On the contrary, BDE-209 was the highest level in sorting worker, and was not detectable in any of the referent group. It demonstrated the occupational exposure at the recycling plant to BDE-209. Multiple regression analysis shows that respirator use for exposure group was negatively associated with serum PBDEs concentration. Per hour use of respirator will reduce 14.5％ of serum PBDEs levels (P < 0.016).
