利用GC-MS技术研究了大气不同粒径颗粒物上多溴联苯醚(PBDEs)的含量和分布,通过总有机碳 (TOC)和PBDE单体含量的相关性探讨了它们在大气中的转移机制,研究结果表明,总颗粒物上∑_15,PBDEs含量为3745.5 pg·m~(-3),BDE47,99,209是三种主要单体.在<0.49μm粒径上∑_15,PBDEs含量最高 (36.4%),<1.5μm的颗粒物上∑_15 PBDEs占61.9%.四溴和五溴的BDE47、66、100和99单体在不同粒径上的含量分布相似,约40%-50%分布在<0.49μm粒径的颗粒物上,约19%-23%分布在0.49-0.95μm粒径的颗粒物上;九溴的BDE208、207的分布和BDE47、99等明显不同,呈马鞍型分布;而十溴的 BDE209主要分布在较粗颗粒上.结果表明大气中低溴PBDE对人体健康有重要影响,同时具有强的长距离迁移能力.BDE28、47、100和99与TOC间有良好的线性关系,可能表明这些低溴PBDE在大气中转移的主要机制是从气相分配进入颗粒相;而高溴的BDE207、208和209与TOC间相关性较差,可能表明高溴 PBDE进人大气中的主要机制是依附在较大颗粒上直接进入大气 |

The level and size distribution of atmospheric PBDEs were analyzed by gas chromatography with mass selective detection (GC-MS).And the correlations between the TOC and the PBDE congener levels were analyzed to discuss the transport mechanism of PBDEs.The results showed that, the total level of Xis PBDEs in the particles was 3745.5 pg·m-3,of which BDE47,99 and 209 were the dominant congeners. Highest ∑_15 PBDEs level was found in the particles of <0.49μm, with a contribution of 36.4%, and the ∑_15 PBDEs level in particles of < 1.5μm contributed 61.9% to the total∑_15PBDEs level. Similar distributions were found for the tetra-and penta-BDE congener BDE47,66,100 and 99, with 400%-50% of PBDEs distributed in the particles of <0.49μm, and 19%-23% in the particles of 0.49-0.95μm. Nona-BDE congener BDE207 and 208 presented a saddle distribution, obviously different from the distribution of BDE47 and 99. Besides, BDE209 was mainly found in the coarse particles. The low brominated PBDEs in the atomspheric particles had great influence on human health, and strong ability to migrate over long distance. The good linear correlations between low brominated PBDE congeners (BDE28,47,100 and 99) and TOC may suggest that the primarily transport mechanism for them is partitioning from gas phase to partical phase. The poor correlations between high PBDE congeners (BDE207,208, and209) and TOC may suggest that high brominated PBDEs transfer into the atmosphere mainly via adhering to the coarse particles |
