摘要

海洋塑料污染是一个全球性问题，需要创新的监测和缓解方法。有关漂浮塑料制品的尺寸、质量和聚合物类型如何随时间变化的信息，可以帮助我们更好地了解支配海面破碎率、扩散、寿命、输入率和丰度的复杂动态。栉水母形海鸟直接摄取漂浮的中型和微型塑料，并将其保留在肫中。因此，海燕可用作生物监测器，记录海洋塑料的丰度和特性趋势。我们比较了从1987-2024年期间南大西洋英纳塞西布尔岛繁殖的四种海燕类群摄入的塑料和从反刍的棕色贼鸥Catharacta antarctica颗粒中收集的塑料的特征。为了评估生物（摄取的）和非生物（海滩）之间的趋势是否持续存在，我们将其与 1984-2023 年间从南非海滩筛出的中型和微型塑料（2-25 毫米）的特征进行了比较。我们从远离当地城市来源区的海滩收集塑料，试图追踪漂浮在海上的塑料而非当地陆地来源的变化。总体而言，几乎没有证据表明摄入或上岸的塑料的大小和质量有变化趋势。海滩上的工业塑料颗粒的平均质量在 2015 年之前有所下降，这表明有一批陈旧的、逐渐被侵蚀的遗留塑料颗粒，但在 2023 年南非海岸发生两起重大塑料颗粒泄漏事件后，这些塑料颗粒的平均质量有所上升。几乎所有被摄入和上岸的塑料都是聚乙烯（PE）或聚丙烯（PP），但硬碎片中聚丙烯与聚乙烯的比例随着时间的推移而增加，而最近工业颗粒中聚乙烯与聚丙烯比例的增加与最近的海上颗粒泄漏事件相吻合。确定摄入和上岸塑料中的聚合物类型对今后的研究很有价值，因为这可能有助于海洋污染管理。

Long-term variations in size and polymer type of meso- and microplastics in seabirds and on beaches since the 1980s

Marine plastic pollution is a global issue that requires innovative ways of monitoring and mitigation. Information on how the size, mass and polymer type of floating plastic items are changing over time may improve our understanding of the complex dynamics governing fragmentation rates, dispersal, longevity, input rates and abundance at the sea surface. Procellariiform seabirds directly ingest floating meso- and microplastics, which they retain in their gizzards. As a result, petrels can be used as biomonitors to document trends in the abundance and characteristics of marine plastics. We compare the characteristics of plastics collected from regurgitated Brown Skua Catharacta antarctica pellets containing the remains and plastics ingested by four petrel taxa breeding at Inaccessible Island, South Atlantic Ocean, at roughly decadal intervals from 1987─2024. To assess if trends persist across biotic (ingested) and abiotic (beaches) compartments, we compare this to the characteristics of meso- and microplastics (2–25 mm) sieved from South African beaches from 1984─2023. Plastics were collected from beaches far from local urban source areas in an attempt to track changes in plastic floating at sea rather than local, land-based sources. Overall, there was little evidence of trends in the size and mass of ingested or beached plastics. The average mass of industrial pellets from beaches decreased up to 2015, suggesting an old, gradually eroding cohort of legacy pellets, but increased in 2023 after two major pellet spills off the South African coast. Nearly all ingested and beached plastics were polyethylene (PE) or polypropylene (PP), but the ratio of PP to PE in hard fragments increased over time, while recent increases in PE:PP ratios in industrial pellets match recent pellet spills at sea. Identifying polymer types in ingested and beached plastics is valuable for future studies, as it may be useful for marine pollution management.

期刊介绍： Environmental Pollution is an international peer-reviewed journal that publishes high-quality research papers and review articles covering all aspects of environmental pollution and its impacts on ecosystems and human health. Subject areas include, but are not limited to: • Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies; • Interlinks between contaminant exposure and biological, ecological, and human health effects, including those of climate change; • Contaminants of emerging concerns (including but not limited to antibiotic resistant microorganisms or genes, microplastics/nanoplastics, electronic wastes, light, and noise) and/or their biological, ecological, or human health effects; • Laboratory and field studies on the remediation/mitigation of environmental pollution via new techniques and with clear links to biological, ecological, or human health effects; • Modeling of pollution processes, patterns, or trends that is of clear environmental and/or human health interest; • New techniques that measure and examine environmental occurrences, transport, behavior, and effects of pollutants within the environment or the laboratory, provided that they can be clearly used to address problems within regional or global environmental compartments.
