| 英文摘要 | Polybrominated diphenyl ethers (PBDEs) are widely used as flame retardants and are prevalent indoors, yet longterm monitoring of indoor PBDEs remains rare. This study systematically investigated the seasonal variations, compositional profiles, and exposure risks of PBDEs across three indoor media-airborne particles (APs, n = 28), vapor phase (n = 28), and dust (n = 47)-collected from four offices. Seasonal trends of PBDEs showed the highest concentrations in autumn and the lowest in winter in both the indoor vapor phase and dust. Correlation analysis revealed a significant negative correlation (p < 0.001) between indoor vapor BDE-17 and BDE-209, suggesting photodegradation of high-weight to low-weight BDEs. In APs, twelve PBDE congeners-excluding BDE-17 and 85-exhibited significant positive correlations (p < 0.05) with PM concentrations. Dust on glass surfaces showed strong correlations between penta-BDEs and octa-/deca-BDEs (r = 0.79). Risk assessments found that dust ingestion was the primary exposure pathway, with students exhibiting the highest total exposure. Dermal contact exposure reached its highest levels in summer, while inhalation, dermal absorption, and dust ingestion were highest in autumn. This study reveals significant seasonal variations in office PBDE concentrations and reinforces the importance of dust as a critical exposure pathway, providing a scientific basis for PBDEs pollution control and health protection strategies. |
