双酚A（BPA）是环境中一种可疑的内分泌干扰物。然而，人们对其在大气中的分布和迁移知之甚少。在这里，BPA的浓度从城市，农村，海洋和极地地区的大气气溶胶中测定使用溶剂萃取/衍生化和气相色谱/质谱技术。全球BRA浓度（1- 17，400 pg m（-3））的范围超过4个数量级，从大陆（南极除外）到偏远地点呈下降趋势。BPA和1，3，5-三苯基苯（塑料燃烧的示踪剂）之间存在正相关关系，表明生活垃圾中的塑料露天燃烧应是大气BRA的重要排放源。我们的研究结果表明，BRA在大气中的无处不在，可能会提高BRA的健康影响的评估，以控制其排放源，例如，从塑料燃烧的要求。(c)2010爱思唯尔有限公司版权所有。
Bisphenol A (BPA) is a suspected endocrine disruptor in the environment. However, little is known about its distribution and transport in the atmosphere. Here, the concentrations of BPA in the atmospheric aerosols from urban, rural, marine, and the polar regions were measured using solvent extraction/derivatization and gas chromatography/mass spectrometry technique. The concentrations of BRA (1-17,400 pg m(-3)) ranged over 4 orders of magnitude in the world with a declining trend from the continent (except for the Antarctica) to remote sites. A positive correlation was found between BPA and 1,3,5-triphenylbenzene, a tracer for plastic burning, in urban regions, indicating that the open burning of plastics in domestic waste should be a significant emission source of atmospheric BRA. Our results suggest that the ubiquity of BRA in the atmosphere may raise a requirement for the evaluation of health effects of BRA in order to control its emission sources, for example, from plastic burning.
