Plastic debris has become a major pollutant in the world's oceans and is found in many seabird species from low to high latitudes. Here we compare levels of plastic ingestion from two surface feeders, northern fulmars (Fulmarus glacialis) and black-legged kittiwakes (Rissa tridactyla), and two pursuit diving species, thick-billed murres (Uria lomvia) and black guillemots (Cepphus grylle) in the Canadian high Arctic. This is the first report quantifying plastic ingestion in kittiwakes in this region, and as predicted, kittiwakes and fulmars had higher frequency of plastic ingestion than guillemots and murres. Despite this, amounts of plastic ingested by birds remain lower than regions farther south.
塑料碎片已成为世界海洋中的主要污染物，在从低纬度到高纬度的许多海鸟物种中都有发现。在这里，我们比较了加拿大北极地区两种表层觅食海鸟——北极海鹦（Fulmarus glacialis）和黑脚三趾鸥（Rissa tridactyla），以及两种追逐潜水海鸟——厚嘴海鸦（Uria lomvia）和黑海雀（Cepphus grylle）的塑料摄入水平。这是该地区关于三趾鸥塑料摄入情况的首次量化报告，正如预期的那样，三趾鸥和海鹦的塑料摄入频率高于海雀和海鸦。尽管如此，鸟类摄入的塑料量仍低于更靠南的地区。
