摘要

全球研究已经研究了塑料聚合物的分布，但很少研究聚合物沉积的驱动因素。在澳大利亚，特别是在西澳大利亚的海滩上，几乎没有做过什么工作。2018年，Wow Ecotours每天从西澳大利亚州南海岸的谢利海滩收集塑料样本。从5个不同的密度类别中提取了873个项目，并使用拉曼光谱法鉴定了它们的聚合物类型。聚合物中含量最多的是高密度聚乙烯，占45%，其次是聚丙烯和低密度聚乙烯，分别占33.5%和14%。陆上风是推动海滩上塑料堆积的主要因素，但这在聚合物之间没有显著差异。春季采集样本的长度、质量和面积波动较大。

Seasonality, wind and characteristics of plastic polymer accumulation on Western Australia's south coast

Global studies have investigated plastic polymer distribution, but few have investigated the drivers of polymer deposition. Little work has been done in Australia, particularly on Western Australian beaches. In 2018, Wow Ecotours collected daily plastic samples from Shelley Beach on the south coast of Western Australia. A subset of 873 items was taken from five different density categories, and their polymer types were identified using Raman Spectrometry. The most abundant polymer was high-density polyethylene 45 %, followed by polypropylene and low-density polyethylene, with 33.5 % and 14 %, respectively. Onshore wind was the predominant factor driving plastic accumulation on the beach, but this did not vary significantly between polymers. The spring season has significant fluctuations in the length, mass, and area of the collected samples.

期刊介绍： Marine Pollution Bulletin is concerned with the rational use of maritime and marine resources in estuaries, the seas and oceans, as well as with documenting marine pollution and introducing new forms of measurement and analysis. A wide range of topics are discussed as news, comment, reviews and research reports, not only on effluent disposal and pollution control, but also on the management, economic aspects and protection of the marine environment in general.
