In modern society, plastic items have become indispensable. The rapid growth of plastic production has led to an increase in the concentration of plastic waste in the environment and, consequently, wildlife has been severely affected. As wide-ranging foragers and predators, aquatic birds are ideal sentinels for monitoring changes in their environment. Plastic found in stomach contents of stranded aquatic birds collected throughout Portugal was examined. Out of the 288 birds processed, 12.9% ingested plastics. Six of the 16 species assessed showed evidence of plastic ingestion. The Lesser Black-backed Gull (18.7%) had the highest incidence while, among those that did ingest plastics, the Northern Gannet (4.8%) had the lowest. User plastics were the most common type of plastic ingested, while microplastics and off/white-clear were the most common size and colour respectively of plastics found. This study sets a first multispecies baseline for incidence of plastic ingestion by aquatic birds in Portugal.
在现代社会，塑料制品已经变得不可或缺。塑料产量的快速增长导致环境中塑料废物的浓度增加，因此野生动物受到了严重影响。作为广泛的觅食者和捕食者，水鸟是监测其环境变化的理想哨兵。检查了在葡萄牙各地搁浅的水鸟胃内容物中发现的塑料。在所处理的 288 只鸟类中，有 12.9%摄入了塑料。在评估的 16 种物种中有 6 种有塑料摄入的证据。黑背鸥（Lesser Black-backed Gull）的发生率最高（18.7%），而在摄入塑料的鸟类中，北方塘鹅（Northern Gannet）的发生率最低（4.8%）。用户塑料是最常见的摄入塑料类型，而微塑料和灰白色则是最常见的塑料大小和颜色。本研究为葡萄牙水鸟摄入塑料的发生率设定了第一个多物种基线。
