Plastic pollution ingestion by seabirds is an increasing environmental problem even in remote areas such as the Arctic, yet knowledge on plastic pollution ingestion by several Arctic seabirds is limited, making it difficult to assess trends. We examined plastic pollution ingestion by northern fulmars (Fulmarus glacialis), black-legged kittiwakes (Rissa tridactyla), thick-billed murres (Uria lomvia) and black guillemots (Cepphus grylle) in the Canadian Arctic to assess species-specific and temporal differences in plastic ingestion over ten years. Seventy-two percent of fulmars and 15% of kittiwakes ingested plastic, while guillemots and murres did not. The number and mass of plastic ingested by fulmars decreased between the two periods (2008 and 2018), but the frequency of occurrence of plastic ingestion did not change, although sample sizes were less than ideal. Future research with larger samples is recommended to reinforce these trends in plastic ingestion by Arctic seabirds.
海鸟吞食塑料污染是一个日益严重的环境问题，即使在北极等偏远地区也是如此，但对于几种北极海鸟吞食塑料污染的了解有限，因此难以评估其趋势。我们研究了加拿大北极地区北方塘鹅（ Fulmarus glacialis ）、黑脚三趾鸥（ Rissa tridactyla ）、厚嘴海鸠（ Uria lomvia ）和黑眉信天翁（ Cepphus grylle ）吞食塑料污染的情况，以评估十种物种特异性和时间差异在塑料摄入。72%的塘鹅和 15%的三趾鸥吞食了塑料，而海鸠和海雀则没有。塘鹅在两个时期（2008 年和 2018 年）之间吞食的塑料数量和质量有所减少，但吞食塑料的频率并没有改变，尽管样本量不理想。建议进行更多的研究，以加强对北极海鸟吞食塑料的这些趋势的研究。
