Diurnal air samples were collected from the E-waste dismantling region Guiyu and the underwear industry region Chendian. This was the first report to present the diurnal variation of PBDEs in the atmosphere. The average concentrations of 11 PBDE congeners were 11,742 pgm(-3) in the daytime, and 4830 pgm(-3) at night in Guiyu, while the concentrations were lower in Chendian with 376 pgm(-3) in the daytime, and 237 pgm(-3) at night. BDE-209 accounted for 22% and 31.3% of the total PBDEs in Guiyu and Chendian, respectively. The diurnal variation trends of BDE-47, -99, -153, -183, and -209 were also analyzed in detail in the two regions.
从电子垃圾拆解地区贵屿和内衣产业地区陈店采集了日间空气样本。这是首份呈现大气中多溴二苯醚（PBDEs）日变化情况的报告。在贵屿，11种多溴二苯醚同系物的平均浓度白天为11742皮克/立方米，夜间为4830皮克/立方米，而在陈店浓度较低，白天为376皮克/立方米，夜间为237皮克/立方米。在贵屿和陈店，十溴二苯醚（BDE - 209）分别占多溴二苯醚总量的22%和31.3%。还详细分析了这两个地区BDE - 47、- 99、- 153、- 183和- 209的日变化趋势。
