Abstract Pollution levels, compositional characteristics and possible sources of polybrominated biphenyls were investigated from 3 environmental samples collected in Taizhou e-waste dismantling area. The health risk assessment model recommended by the US EPA and Chinese exposure parameters were applied to assess the health risk of the dismantling area. ∑sub>9PBBs concentrations in the atmosphere, soil and groundwater were 2867.99pg/m³, 868.50mg/kg and 1.35μg/L, respectively, and the contributions of the PBB homologues varied. Source analysis shows that PBBs in environmental media are mainly derived from the dismantling activities of electronic waste. Industrial production activities, metabolic activities of high brominated PBBs, atmospheric dry and wet deposition, surface runoff may also have some influences. The results of health risk assessment showed that the carcinogenic risk of male and female was 1.43×10^-2 and 1.44×10^-2, respectively. The non-carcinogenic risk was 8.15×10^-4 and 8.22×10^-4, respectively, which exceeded the maximum acceptable risk level recommended by ICRP.
