The Mediterranean basin is a marine environment with elevated pollution levels and plastic waste. Seabirds are marine top predators that cover wide ranges and congregate in colonies during breeding. As bionindicators they can offer an insight in the pollution status of their marine habitat. This project aims to assess pollutant concentrations throughout different periods in Scopoli´s shearwaters from three areas in the Medi-terranean Sea, where ecotoxicology has rarely been investigated. We will assess the relationships of different pollutants and how they vary throughout different seasons, breeding phases and according to diet. The impacts of plastic pollution on marine organisms are recently discussed and it is not clear wether ingested microplastics or larger plastic particles can lead to higher pollutant burdens or have impacts on reproduction or behaviours. We aim to analyse the relationship between plasticizers and other pollutants in order to investigate the potential hazards for marine animals due to plastic ingestion. The results of this project can 1) close knowledge gaps about contaminants in free living marine organisms in the central, south and east of the Mediterranean Sea, 2) give insight to pollutant impacts on behaviour and reproduction on shearwaters and 3) contribute with field data to the up-to-date scientific discussion about potential hazards of pollutants in relation to ingested plastic particles under environmental concentrations.

地中海盆地是一个海洋环境，污染水平和塑料废物都很高。海鸟是海洋顶级掠食者，覆盖范围广，在繁殖期间聚集在殖民地。作为生物指示器，它们可以提供对其海洋栖息地污染状况的洞察力。该项目旨在评估地中海三个地区斯科波利剪切水域不同时期的污染物浓度，这些地区很少进行生态毒理学研究。我们将评估不同污染物之间的关系，以及它们在不同季节、繁殖阶段和饮食中的变化。最近讨论了塑料污染对海洋生物的影响，目前尚不清楚摄入的微塑料或较大的塑料颗粒是否会导致更高的污染物负担或对生殖或行为产生影响。我们的目的是分析增塑剂和其他污染物之间的关系，以调查由于塑料摄入对海洋动物的潜在危害。该项目的结果可以1）填补地中海中部，南部和东部自由生活的海洋生物中污染物的知识空白，2）深入了解污染物对行为和繁殖的影响，3）通过现场数据促进最新的科学讨论，讨论与环境浓度下摄入的塑料颗粒有关的污染物的潜在危害。
