Plastic debris has become ubiquitous in the marine environment and seabirds may ingest debris which can have deleterious effects on their health. In the North Atlantic Ocean, surface feeding seabirds typically ingest high levels of plastic, while the diving auks which feed in the water column typically have much lower levels. We examined 186 thick-billed murres from five colonies in the eastern Canadian Arctic for ingested plastic debris. Approximately 11% of the birds had at least one piece of plastic debris in their gastrointestinal tracts, with debris dominated by user plastics. This is the first report of ingested plastics in an auk species in Canada's Arctic, and the highest incidence of plastic ingestion to date for thick-billed murres (Uria lomvia).
塑料碎片在海洋环境中无处不在，海鸟可能会摄入这些碎片，这对它们的健康可能产生有害影响。在北大西洋，表面觅食的海鸟通常会摄入大量的塑料，而在水柱中觅食的潜水海雀则通常摄入较少的塑料。我们检查了来自加拿大北极东部五个繁殖地的 186 只厚嘴海鸦，以检查它们摄入的塑料碎片。大约 11%的鸟类的胃肠道中至少有一块塑料碎片，这些碎片主要是消费类塑料。这是在加拿大北极地区的海雀物种中首次报告摄入塑料的情况，也是迄今为止厚嘴海鸦摄入塑料的最高发生率 (Uria lomvia)。
