This baseline study describes the microplastic (MPs) problem on seven beaches located on Agadir, central Atlantic coast of Morocco. Microplastics abundances (densities) ranged from 7680 MPs/kg to 34,200 MPs/kg above other world beaches. The following shapes were found: fibers, fragments, films, and pellets. Fibers were the dominant typology with a 73%. Polyethylene (PE) was the predominant polymer in all beaches with an average percentage of 59%, followed by Polypropylene (PP - 18%), Polystyrene (PS - 9%), Polyvinyl chloride (PVC - 8%), and Ethylene-vinyl acetate (EVA - 6%). Microplastics abundances presented in this work suggest continuous inputs of plastics of all sizes and types. Also, all observed shapes highlight a combination of sources (primary and secondary). Central Atlantic Moroccan beaches are currently affected by extreme values of MPs that demand urgent interventions to restore environmental quality.
本基线研究描述了位于摩洛哥大西洋中部海岸阿加迪尔的 7 个海滩上的微塑料 (MPs) 问题。微塑料丰度（密度）范围从每公斤 7680 个 MPs 到 34200 个 MPs，高于其他世界海滩。发现的形状有纤维、碎片、薄膜和颗粒。纤维是主要类型，占 73%。在所有海滩中，聚乙烯 (PE) 是主要的聚合物，平均比例为 59%，其次是聚丙烯 (PP - 18%)、聚苯乙烯 (PS - 9%)、聚氯乙烯 (PVC - 8%) 和乙烯-醋酸乙烯酯 (EVA - 6%)。本工作中提出的微塑料丰度表明，各种大小和类型的塑料都在持续输入。此外，所有观察到的形状都突出了各种来源（原发性和继发性）的结合。目前，摩洛哥大西洋中部的海滩受到 MPs 极值的影响，需要紧急干预措施来恢复环境质量。
