In this study, based on data collected by citizen science, we studied the abundance, spatial and temporal distribution of marine litter in three beaches of the Moroccan Mediterranean. A total of 14,042 litter items were collected with an average abundance of 0.58 items/m. The most of litter were composed of anthropic polymeric materials, representing 74 % of the total litter collected. Plastics account for the majority of the items collected and are mainly caps/lids, crisp/sweet packets, plastic/polystyrene, cigarette butts and small plastic bags. Litter abundance displayed significant seasonal differences, with the highest during summer. Tourism and poor waste management practices are the major sources of plastic on the beaches surveyed. The use of the Clean Coast Index (CCI) and the Plastics Abundance Index (PAI) permits the classification of the three beaches in the Moroccan Mediterranean as a "moderately clean" coastal area with a "very high abundance" of plastics. In addition, the Hazardous Items Index (HII) allows classification of the region as highly polluted by hazardous litter. Best management measures are needed to promote the environmental quality of the beaches of the Moroccan Mediterranean.
在这项研究中，我们基于公民科学收集的数据，研究了摩洛哥地中海三个海滩的海洋垃圾的丰度、时空分布。共收集了 14042 件垃圾，平均丰度为 0.58 件/米。大部分垃圾由人为聚合材料组成，占收集到的垃圾总量的 74%。塑料占收集到的物品的大多数，主要是瓶盖/盖子、薯片/糖果包、塑料/聚苯乙烯、烟头和小塑料袋。垃圾丰度显示出显著的季节性差异，夏季最高。旅游和垃圾管理不善是海滩上塑料的主要来源。使用清洁海岸指数（CCI）和塑料丰度指数（PAI）可以将摩洛哥地中海的三个海滩分类为“中度清洁”的沿海地区，塑料的“丰度非常高”。此外，危险物品指数（HII）允许将该地区归类为受危险垃圾高度污染的地区。需要采取最佳管理措施来提高摩洛哥地中海海滩的环境质量。
