Polybrominated diphenyl ethers (PBDEs) have been used extensively in electrical and electronic products, but little is known about the exposure level in the electrical appliance factories workers and nearby local residents. In this study, we assessed body burdens of PBDEs in 194 Chinese injection workers from electrical appliance factories and also measured 205 blood samples from catering workers, leather factory workers, umbilical cord and infertile men for comparison. Twelve PBDE congeners in serum samples were measured by GC–MS. The highest concentration for total PBDEs was found in injection workers, which is positively correlated to employment duration. BDE-209 was the most dominant congener followed by BDE-47, 28 and 99. We also found the presence of all twelve PBDEs in cord blood, suggesting an evidence of fetal exposure. Concentration of BDE-47 was particularly higher in serum samples from infertile men in comparison with that of catering workers and leather factory workers.
► The highest mean concentration for ∑PBDEs was found in injection workers.
► BDE-209 was the most dominant congener followed by BDE-47, 28 and 99.
► All twelve PBDEs were detected in cord blood sample.
► BDE-47 was particularly high in serum samples from infertile men.
