| 中文摘要 |
| 利用大流量主动采样技术在苏州市工业园区工厂车间、办公室、住宅区和风景区，采集PM10样品，GC-MS测定PM10中8种PBDEs的含量.室内PM10中PBDEs总浓度范围为9.22~64.15 pg·m-3（均值为20.93 pg·m-3），室外样品中PBDEs总浓度范围为1.06~8.44 pg·m-3（均值为5.11 pg·m-3），室内含量显著高于室外含量.PM10中∑8PBDEs平均浓度从高到低顺序依次为工业车间、办公室、住宅区和室外大气，与其他地区室内外颗粒物含量相比，苏州室内外大气颗粒物中PBDEs都处于较低水平.室内外大气中BDE-209是最主要化合物（平均占总PBDEs的63%），其次为BDE-99和BDE-47.车间员工、办公室员工和儿童的PBDEs日呼吸摄入剂量分别为3.75、2.78和2.60 pg·（kg·d）-1，这表明苏州居民呼吸暴露PBDEs的潜在健康危害并不明显. |
| 英文摘要 |
| Eight polybrominated diphenyl ether (PBDE) congeners in indoor and outdoor air particles were collected using higher-volume active sampling techniques from different functional areas, including an industrial workplace, office, domestic area, and scenic area in an industrial zone, in Suzhou city, and the samples were analyzed by GC-MS. The total concentration of PBDEs ranged from 9.22-64.15 pg·m-3 (average 20.93 pg·m-3), and 1.06-8.44 pg·m-3(average 5.11 pg·m-3)in indoor and outdoor air, respectively. The results showed that the concentrations of PBDEs in indoor PM10 was significantly higher than that in the outdoor PM10. The average concentrations of PBDEs in the air of the different sampling areas were in the order:industrial workplace-1 by the workers in the workplace, workers in office, and toddlers, respectively. Results showed that inhalation exposure to PBDEs did not cause potential health risks in the local residents of Suzhou. |
