We used the eggs of an avian sentinel, the Northern gannet (Morus bassanus), to determine long-term (1977-2007) trends in PBDE contamination in Western Atlantic (Ailsa Craig colony) and North Sea (Bass Rock colony) waters around the UK. BDEs 47, 49, 99, 100, 153, 154 were the most abundant and were found in all eggs. Individual congener and ΣPBDE concentrations in eggs from both colonies increased mainly from the late 1980s, peaked in 1994, and then rapidly declined so that concentrations in 2002 were similar to or lower than those in the 1970s and 1980s. The PBDE congener profile and temporal variation in PBDE concentrations suggests that the Penta-BDE technical formula was the main source of PBDE contamination. However, contributions of heavier BDE congeners to ΣPBDE concentrations have increased over time, suggesting other sources are becoming more important. PBDEs had no measurable effect on egg volume or eggshell index.
我们使用一种禽类哨兵鸟（北方塘鹅）的卵来确定英国周边西大西洋（艾尔萨克雷格繁殖地）和北海（巴斯岩繁殖地）水域中多溴二苯醚的长期（1977-2007 年）污染趋势。BDE-47、BDE-49、BDE-99、BDE-100、BDE-153 和 BDE-154 是最丰富的，在所有的卵中都有发现。两个繁殖地的卵中单个同族体和ΣPBDE 的浓度主要从 20 世纪 80 年代末开始增加，在 1994 年达到峰值，然后迅速下降，以至于 2002 年的浓度与 20 世纪 70 年代和 80 年代相似或更低。多溴二苯醚同族体的分布情况和多溴二苯醚浓度的时间变化表明，五溴二苯醚技术配方是多溴二苯醚污染的主要来源。然而，随着时间的推移，较重的多溴二苯醚同族体对ΣPBDE 浓度的贡献有所增加，这表明其他来源变得越来越重要。多溴二苯醚对卵体积或卵壳指数没有可测量的影响。
