Plastic pollution continues to prevail across Arctic marine environments, readily available for marine organisms to ingest, especially seabirds. Seabird plastic ingestion datasets often lack standardized time series that allow for trend analysis. We examine the recent status of plastic ingestion (≥ 1 mm) in thick-billed murres (Uria lomvia) using standardized methods to assess spatial differences and time trends over two decades (2007–2021). In 2021, 7 % of the 43 thick-billed murres we examined from this region ingested plastic; 1 piece of plastic in three separate individuals. No significant temporal or spatial differences in murre plastic ingestion were observed. Therefore, plastic pollution (≥ 1 mm) currently poses a low risk to Arctic breeding murres. The long-term monitoring of plastic ingestion in this species should continue as murres have economic and cultural importance to communities and provide insight to marine plastic pollution trends.

来自加拿大北极高地的厚嘴海鸥 （Uria lomvia） 的塑料摄入


塑料污染在北极海洋环境中仍然普遍存在，海洋生物，尤其是海鸟很容易摄入。Seabird 塑料摄取数据集通常缺乏允许进行趋势分析的标准化时间序列。我们使用标准化方法检查了厚嘴海鸦 （Uria lomvia） 塑料摄入 （≥ 1 毫米） 的近期状况，以评估二十年（2007-2021 年）的空间差异和时间趋势。2021 年，我们在该地区检查的 43 只厚嘴海鸥中有 7% 摄入了塑料;1 块塑料分为三个独立的个体。未观察到 murre 塑料摄入的显着时间或空间差异。因此，塑料污染（≥ 1 毫米）目前对北极繁殖海鸦构成的风险较低。应继续对该物种的塑料摄入量进行长期监测，因为海鸦对社区具有经济和文化重要性，并提供了对海洋塑料污染趋势的见解。
