This study investigated the spatial and temporal patterns of polycyclic aromatic hydrocarbons (PAHs) in kentish plover (Charadrius alexandrinus) eggs after a major oil spill (Prestige, November 2002) in northwest Iberia. We analysed a total of 77 eggs from 10 breeding localities of the Iberian Atlantic coast, 9 located along the Galician coast (NW Spain) and one in the Ria de Aveiro (Portugal). General linear mixed models did not show a significant effect of the area on the total PAH levels and on each compound, probably due to the spread of pollution caused by the Prestige ship and the industrial and harbour pollutions of the Ria de Aveiro (Portugal). In contrast, the PAH levels were significantly affected by year. The PAH levels decreased from 2004 to 2006 but strongly increase and showed a different pattern of PAH accumulation in 2007. These results may be due to tetra- and pentacyclic compounds from forest fires that occurred during summer 2006.
本研究调查了 2002 年 11 月西班牙西北部发生的“威望号”（Prestige）重大溢油事件后，多环芳烃（PAHs）在蛎鹬（Charadrius alexandrinus）卵中的时空分布模式。我们分析了来自伊比利亚大西洋海岸 10 个繁殖地的总共 77 枚卵，其中 9 枚位于加利西亚海岸（西班牙西北部），1 枚位于阿威罗河口（葡萄牙）。一般线性混合模型并未显示出区域对总多环芳烃水平和每种化合物的显著影响，这可能是由于“威望号”船造成的污染扩散以及阿威罗河口（葡萄牙）的工业和港口污染所致。相比之下，多环芳烃水平受到年份的显著影响。多环芳烃水平从 2004 年到 2006 年下降，但在 2007 年强烈增加，并显示出不同的多环芳烃积累模式。这些结果可能是由于 2006 年夏季发生的森林火灾产生的四元和五元化合物所致。
