Morocco is well known for its attractive Mediterranean beaches, which play an important economic role. With the fast development and growth, these beaches have become more contaminated by marine debris. This paper examined the abundance, composition and marine debris sources on five beaches in the Moroccan Mediterranean during 2019 four seasons. A total of 7839 marine debris were collected from the five beaches with a total weight of 231 kg. The average density of the debris collected was 0.20 ± 0.098 items/m². Polymer materials constituted the majority of debris found, with a percentage of 71.36%, followed by paper/cardboard (11.50%), metal (5.77%), processed wood (5.34%), cloth/textile (2.51%) and glass/ceramics (1.76%). Human recreational activities were the main source of debris (70.13%), followed by smoking-related (13.98%). Debris density appears to be particularly influenced by beach users. Awareness campaigns are needed for beach users to improve the quality of the beaches.

摩洛哥以其迷人的地中海海滩而闻名，这些海滩起着重要的经济作用。随着快速发展和壮大，这些海滩已被海洋垃圾所污染。本文研究了2019年四个季节摩洛哥地中海五个海滩上海滩的丰度，成分和海洋垃圾来源。从五个海滩收集了总共7839块海洋垃圾，总重231公斤。收集的碎屑平均密度为0.20±0.098个/ m ²。聚合物材料占发现的碎片的大部分，占71.36％，其次是纸/纸板（11.50％），金属（5.77％），加工木材（5.34％），布/纺织品（2.51％）和玻璃/陶瓷（1.76％）。人类娱乐活动是垃圾的主要来源（70.13％），其次是与吸烟有关的垃圾（13.98％）。碎片密度似乎特别受到海滩使用者的影响。海滩使用者需要提高意识，以提高海滩质量。
