Relative Composition and Atmospheric Transport of Organochlorine Pollutants in Tianjin-Changdao Region

  • 摘要: 为了研究持久性有机污染物(POPs)的区域分布、大气传输与来源,采用被动采样技术于2006年7月—2008年6月在山东长岛与天津同步采集大气样品.色谱/高分辨质谱(GC/HRMS)分析数据表明,有机氯污染物化学组成季节变化明显.天津-长岛区域的大气样品主要按照季节聚类,表现出有机氯污染的区域性特征.天津和长岛相距约400 km,两地化学组成的相似性归因于有效的大气扩散和长距离传输.同时,天津点位的源区特征,长岛渔港和船厂含DDTs船舶防污漆的使用作为一种重要的DDTs排放,在化学组成和聚类结果中,均得到了客观的反映.有机氯污染物相对化学组成可以作为一种“指纹”和“探针”技术,研究大气污染物的传输和区域分布.
