摘要(Abstract)：

2013年10月至2014年7月,在太原城区,分4个月采集大气细颗粒物,每个月选取4个样品,分析了颗粒物上8种多溴联苯醚(PBDEs)和6种新型溴代阻燃剂(NBFRs)的浓度与组成。结果表明,大气PM2.5样品中PBDEs和NBFRs总浓度算术平均值分别为(10.9±10.3)pg·m-3和(22.3±24.7)pg·m-3,其中BDE-209、HBB和DBDPE是溴代阻燃剂中的主要污染物。季节变化来看,秋季样品中总PBDEs和总NBFRs的浓度要高于其他季节,夏季最低;化合物组成上,秋季样品中BDE-209含量较低,而NBFRs中HBB含量较高。相关分析显示,溴代阻燃剂的变化与颗粒物浓度和有机质的相关性不大,与大气温度与无显著性相关,而主要与气团来源有关。城市儿童的吸入暴露量约为成人的2~3倍,反映出PM2.5中溴代阻燃剂对城镇居民尤其是儿童的潜在健康危害仍不容忽视。
