摘要

本文介绍了斯基克达海岸线(地中海西南部,阿尔及利亚东北部)五个沙滩上的微塑料问题,确定了它们的大小、时空分布、形状、聚合物类型、影响和潜在来源。本研究提供的数据是在 2019 年 5 月(春季)和 9 月(秋季/秋季)的两次实地调查中收集的。总体而言,春季所有海滩的微塑料平均丰度为 6174 个/平方米,秋季为 6183 个/平方米,是阿尔及利亚报告的微塑料最高水平。最常见的微塑料类型是碎片、颗粒、泡沫和纤维,占本研究收集的微塑料形状的 98%以上。我们的研究结果表明,在所研究的海滩上,微塑料碎片具有持久性,海流、风向、冲滩、沉积、沙丘和碎片等环境因素都会对海滩上塑料碎片的分布和积累产生重大影响。

Persistence and potential increasing accumulation of microplastic pollution on the Skikda coast (northeastern Algeria).

This paper describes the microplastic problems on five sandy beaches along the Skikda coastline (southwestern Mediterranean, northeastern Algeria), defining their magnitudes, spatial-temporal distributions, shapes, polymer types, impacts, and potential sources. The data presented in this study were collected during two field surveys in May (spring) and September (autumn/fall) of 2019. Overall, the average abundance of microplastics across all beaches was 6174 items/m2 in spring and 6183 items/m2 in autumn, representing the highest level of MPs ever reported in Algeria. The most common microplastic types found were fragments, pellets, foams and fibers, accounting for >98 % of the microplastic shapes collected in this study. Our findings highlight the persistence of MPs on the studied beaches and that environmental factors such as currents, wind directions, beaching, sedimentation, dunes, and fragmentation all significantly impact the distribution and accumulation of plastic debris on beaches.

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.
