Abstract

Microplastics (MPs) are considered one of the main pollution issues on the planet. This study constitutes the initial assessment of MPs on sandy beaches in Cuba. Four beaches with different characteristics and anthropogenic activities were selected on the north and south coasts of the island's central region. MPs (0.3–5 mm) were identified at three out of four beaches studied, with 0–196 MPs m² (0–47 MPs kg⁻¹). The MPs found on the south coast, Tetas de Tomasa Beach in Cienfuegos Bay, exhibited the highest average abundance, 95 ± 61 MPs m², followed by Rancho Luna with 3 ± 4 MPs m². On the north coast, Las Gaviotas Beach showed an average abundance of 2 ± 4 MPs m², and no MPs were found at Cañón Beach. Fragments were the main morphology (55 %), while the most prevalent colors were white/transparent (65.2 %) and blue (19.4 %). Polyethylene was the predominant synthetic polymer (52 %), followed by polypropylene (32 %) and polystyrene (14 %).

古巴沙滩上塑料微粒（0.3-5毫米）的评估

微塑料（MPs）被认为是地球上的主要污染问题之一。这项研究构成了对古巴沙滩上的MPs的初步评估。在岛屿中部地区的南北海岸选择了四个具有不同特征和人为活动的海滩。在所研究的四个海滩中，有三个海滩发现了MPs（0.3-5毫米），其面积为0-196 MPs m2 （0-47 MPs kg−1）。南海岸西恩富戈斯湾的Tetas de Tomasa海滩的MPs平均丰度最高，为95±61 MPs m2，其次是Rancho Luna，为3±4 MPs m2。北岸Las Gaviotas海滩平均丰度为2±4 MPs m2， Cañón海滩未发现MPs。碎块是主要形态（55%），白色/透明（65.2%）和蓝色（19.4%）是最常见的颜色。聚乙烯是主要的合成聚合物（52%），其次是聚丙烯（32%）和聚苯乙烯（14%）。

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.
