Marine plastic pollution is an increasing, and global, environmental issue. Numerous marine species are affected by plastic debris through entanglement, nest incorporation, and ingestion, which can lead to lethal and sub-lethal impacts. However, in the northeastern Atlantic Ocean, an area of international importance for seabirds, there has been little effort to date to assess information from studies of wildlife and plastic to better understand the spatiotemporal variation of how marine plastic affects different seabird species. To improve our understanding of seabirds and marine plastic in this region, we completed a synthesis of the published and grey literature to obtain information on all known documented cases of plastic ingestion and nest incorporation by this group. We found that of 69 seabird species that commonly occur in the northeastern Atlantic, 25 had evidence of ingesting plastic. However, data on plastic ingestion was available for only 49% of all species, with 74% of investigated species recorded ingesting plastic. We found only three published studies on nest incorporation, for the Northern Gannet (Morus bassanus) and Black-legged Kittiwake (Rissa tridactyla). For many species, sample sizes were small or not reported, and only 39% of studies were from the 21st century, whilst information from multiple countries and years was only available for 11 species. This indicates that we actually know very little about the current prevalence of plastic ingestion and nest incorporation for many species, several of them globally threatened. Furthermore, in the majority of studies, the metrics reported were inadequate to carry out robust comparisons among locations and species or perform meta-analyses. We recommend multi-jurisdictional collaboration to obtain a more comprehensive and current understanding of how marine plastic is affecting seabirds in the northeastern Atlantic Ocean.

海洋塑料污染是一个日益严重的全球性环境问题。大量的海洋物种通过纠缠，巢整合和食入而受到塑料碎片的影响，这可能导致致命和次致命的影响。但是，在东北大西洋，海鸟具有国际重要性的地区，迄今为止，几乎没有做出任何努力来评估来自野生动植物和塑料研究的信息，以更好地了解海洋塑料如何影响不同海鸟物种的时空变化。为了增进我们对该地区海鸟和海洋塑料的了解，我们完成了已出版的灰色文献的综合，以获取有关该小组所有已知文献中有关塑料摄入和筑巢的案例的信息。我们发现，在大西洋东北部常见的69种海鸟物种中，有25种具有摄入塑料的证据。但是，只有49％的物种获得了有关塑料摄入的数据，其中74％的被调查物种记录了塑料的摄入。我们发现只有三篇有关北塘鹅巢筑巢的已发表研究（桑us（Morus bassanus）和黑脚Kittiwake（Rissa tridactyla）。对于许多物种，样本量很小或没有报道，只有39％的研究来自21世纪，而来自多个国家和年份的信息仅适用于11个物种。这表明我们实际上对许多物种目前的塑料摄入和鸟巢掺入情况了解甚少，其中有几种受到全球威胁。此外，在大多数研究中，所报告的指标不足以对地点和物种进行可靠的比较或进行荟萃分析。我们建议进行跨辖区的合作，以更全面和最新地了解海洋塑料如何影响东北大西洋的海鸟。
