Abstract

Birds are considered as good bio-monitors and they can provide highly valuable data about the level of contamination in their habitat. During the design of biomonitoring studies one of the first issues after choosing species is the choice of biological material. Non-lethally collected samples have recently been gaining greater attention as they offer several ethical and practical advantages. However, not all sample matrices are suitable for biomonitoring of certain compounds. The main aim of this review is to bring to closer attention the utility of non-lethally collected samples from avian species, based on recent literature. The selected samples are feathers, blood, preen oil and eggs, as these are the types of biological materials most often chosen and may reveal birds’ exposure from their diet. It is not my intention to single out one of them as the ultimate tool for organic compound analysis, but rather to present their utility in order to support or advise on future choices, as a single matrix might not be sufficient to fully evaluate birds’ exposure. Therefore, this paper presents the current status of the non-lethal approach in avian species for determination of PCBs, OCPs, PBDEs and PFASs.

摘要

鸟类被认为是良好的生物监测器，它们可以提供有关其栖息地污染程度的非常有价值的数据。在生物监测研究的设计过程中，选择物种后的首要问题之一是生物材料的选择。非致死性收集的样本最近受到了更多关注，因为它们提供了一些道德和实践优势。然而，并非所有样品基质都适合某些化合物的生物监测。本综述的主要目的是根据最近的文献，更加密切地关注从鸟类物种中收集的非致死样本的效用。选定的样本是羽毛、血液、羽毛油和鸡蛋，因为这些是最常选择的生物材料类型，可以揭示鸟类从其饮食中接触的情况。我无意挑出其中一个作为有机化合物分析的最终工具，而是展示它们的效用以支持或建议未来的选择，因为单一矩阵可能不足以全面评估鸟类的暴露情况. 因此，本文介绍了在鸟类物种中测定 PCBs、OCPs、PBDEs 和 PFASs 的非致死方法的现状。
