Plastic pollution has become a major issue for marine ecosystems. Seabirds are particularly vulnerable to this pollution and are very good indicators of the ecological state of marine ecosystems. This study aims to analyse the presence of plastics in the digestive tracts of two seabird species: the Atlantic puffin (Fratercula arctica) and the razorbill (Alca torda), collected along the Andalusia coast in Southern Spain. A total of 123 carcasses were collected during the autumn and winter seasons of 2022-2024. The results showed a significantly higher presence of plastics in Atlantic puffin (65.0 %) compared to razorbill (18.4 %). The mean number of plastics per puffin was 2.50 ± 2.75, while per razorbill was 0.31 ± 0.94. The predominant type of ingested plastic was fibres in both Atlantic puffin (38.0 %, n = 19) and razorbill (40.6 %, n = 13), with an average size of 1.58 ± 0.74 mm and 2.13 ± 1.98 mm, respectively. The predominant colour was black in both species (22.0 % in puffin and 46.9 % in razorbill), and polyethylene (39.5 %) was the most common plastic polymer, consisting of highly fragmented particles with low levels of adhering heavy metals. This study supports the growing concern about plastic pollution in marine environment, showing that alcid populations are ingesting plastics, potentially threatening these vulnerable species.
塑料污染已成为海洋生态系统的一个主要问题。海鸟尤其容易受到这种污染的影响，并且是海洋生态系统生态状况的良好指标。本研究旨在分析在西班牙南部安达卢西亚海岸收集的两种海鸟——大西洋海鹦（角嘴海雀）和刀嘴海雀消化道中塑料的存在情况。在2022年至2024年的秋冬季节共收集了123具尸体。结果显示，大西洋海鹦体内塑料的存在率（65.0%）显著高于刀嘴海雀（18.4%）。每只海鹦体内塑料的平均数量为2.50±2.75个，而每只刀嘴海雀为0.31±0.94个。在大西洋海鹦（38.0%，n = 19）和刀嘴海雀（40.6%，n = 13）中，摄入的塑料的主要类型都是纤维，平均尺寸分别为1.58±0.74毫米和2.13±1.98毫米。两种海鸟中塑料的主要颜色均为黑色（海鹦中为22.0%，刀嘴海雀中为46.9%），聚乙烯（39.5%）是最常见的塑料聚合物，由高度破碎的颗粒组成，附着的重金属含量较低。这项研究支持了对海洋环境中塑料污染日益增长的担忧，表明海雀种群正在摄入塑料，这可能会威胁到这些脆弱的物种。
