Microplastics (MPs) have attracted global attention due to their ubiquity and potential impact on the environment. However, MPs are poorly documented along the Algerian coast. To address this data gap, this study investigated the presence of MPs on three recreational beaches in western Algeria (Stidia, Sablettes and Mersat El Hadjaj). The mean MP abundance for the three beaches was estimated at 55.47 ± 48.01 items/m. Characterization of MPs shape revealed that fragments (79.81 %) were dominant, followed by pellets (10.58 %), filaments (5.57 %), and foam (3.85 %). An assessment of the Microplastic Pollution Index, the Pellet Pollution Index, and the Coefficient of Microplastic Impact, revealed the presence of very low to moderate levels of MPs on the beaches. This presence was associated with minimal beach pollution and moderate overall impact. The sector analysis approach results confirm that there are two different magnitudes of MPs presence that can negatively impact on the environmental quality of the studied beaches.
微塑料（MPs）因其无处不在和对环境的潜在影响而引起了全球关注。然而，在阿尔及利亚沿海地区，MPs 的相关数据记录很少。为了解决这一数据空白，本研究调查了阿尔及利亚西部三个休闲海滩（Stidia、Sablettes 和 Mersat El Hadjaj）的 MPs 存在情况。三个海滩的平均 MPs 丰度估计为 55.47 ± 48.01 个/米。对 MPs 形状的特征描述表明，碎片（79.81%）占主导地位，其次是颗粒（10.58%）、纤维（5.57%）和泡沫（3.85%）。微塑料污染指数、颗粒污染指数和微塑料影响系数的评估表明，海滩上存在非常低到中等水平的 MPs。这种存在与海滩污染程度较低和整体影响程度中等有关。部门分析方法的结果证实，有两种不同程度的 MPs 存在会对研究海滩的环境质量产生负面影响。
