我们检测了1988-1990年间采集的24种1799只海鸟的肠道内容物，以评估海鸟在阿拉斯加亚北极水域摄取的塑料颗粒的类型和数量。在被发现摄取塑料的15种物种中，大多数是水面觅食的(剪切鱼、海燕、海鸥)或以浮游生物为食的潜水员(海雀、海雀)。在被检测的4417个塑料颗粒中，76%是工业颗粒，21%是用户塑料的碎片。摄取率因地域而异，但没有明显的趋势，塑料摄取率在地区内的物种之间的差异远远大于地区之间的物种内的差异。与1969-1977年收集的37种1968年海鸟的类似数据相比，海鸟对塑料的摄取在研究间隔10-15年期间显着增加。这表现在：(I)摄取塑胶的物种总数增加；(Ii)摄取塑胶的物种内塑胶粒子出现的频率增加；及(Iii)这些物种的个人摄取的塑胶粒子的平均数目增加。
We examined gut contents of 1799 seabirds comprising 24 species collected in 1988–1990 to assess the types and quantities of plastic particles ingested by seabirds in the subarctic waters of Alaska. Of the 15 species found to ingest plastic, most were surface-feeders (shearwaters, petrels, gulls) or plankton-feeding divers (auklets, puffins). Of 4417 plastic particles examined, 76% were industrial pellets and 21% were fragments of ‘user’ plastic. Ingestion rates varied geographically, but no trends were evident and rates of plastic ingestion varied far more among species within areas than within species among areas. Comparison with similar data from 1968 seabirds comprising 37 species collected in 1969–1977 revealed that plastic ingestion by seabirds has increased significantly during the 10–15-year interval between studies. This was demonstrated by: (i) an increase in the total number of species ingesting plastic; (ii) an increase in the frequency of occurrence of plastic particles within species that ingested plastic; and, (iii) an increase in the mean number of plastic particles ingested by individuals of those species.
