项目摘要

Global industrial production and consumer behavior lead to increasing contamination of the oceans. Therefore, there is a growing need to understand the prevalence and risk associated with exposure of wildlife to sources of contamination such as plastics and mercury, especially in remote areas such as the Southern Ocean. To compare the exposure to plastics among petrels sampled at different Antarctic and subantarctic sites and times of the season, the presence of three common plasticizers will be determined in the waxy preen oil using a recently established GC-MS protocol. In addition, mercury will be measured from the same birds using feather samples which integrate the exposure to mercury between two successive moults and blood samples which are representative of the present exposure. We will focus on small petrels (storm-petrels, prions and blue petrels) and will also analyse samples from storm-petrels breeding in the North-east Pacific to enable a comparison to an area known to have high plastic exposure. We will test for differences in the level of contamination associated with breeding and inter-breeding distribution and trophic level (determined using compound-specific stable isotope analyses). We will further compare samples collected during the early and late Antarctic breeding season (e.g. November versus March) to quantify carry-over effects of the exposure in the inter-breeding season.

全球工业生产和消费者行为导致海洋污染的增加。因此，越来越需要了解与野生动植物暴露于塑料和汞之类的污染源相关的普遍性和风险，尤其是在南大洋等偏远地区。为了比较在不同南极和亚半北极部位和季节中抽样的塑料中暴露于塑料中，使用最近确定的GC-MS方案将在蜡状的Preen Oil中确定三种常见的增塑剂。此外，将使用羽毛样品从相同的鸟类中测量汞，这些羽毛样品将暴露于两个连续的蜕皮和血液样本之间的汞中，这些汞代表了目前的暴露。我们将专注于小海心（暴风雨，prions和蓝色的石油），还将分析东北太平洋风暴前繁殖的样品，以使其与已知具有高塑料暴露的区域进行比较。我们将测试与繁殖和繁殖分布和营养水平相关的污染水平的差异（使用化合物特异性稳定同位素分析确定）。我们将进一步比较在南极繁殖季节（例如11月与3月）中收集的样品，以量化繁殖季节暴露的结转影响。
