This study represents the first assessment of beach litter on an island of the west African archipelagic state of Cape Verde. On five beaches of São Vicente, litter was collected along transects and classified according to the OSPAR protocol, with the Matrix Scoring Technique used to allocate it to four sources. Beach litter on São Vicente is highly variable in both amount and composition, while land- and sea-based sources contribute to litter loads to different extents depending on the use and geographic orientation of the beach. Four of the five surveyed beaches exhibited litter loads that were similar to pollution levels previously described for other oceanic islands, while a north-eastern-facing beach featured exceptionally high loads. This was presumably because it receives litter from distant sources due to its exposure to a major ocean surface current.
本研究首次评估了西非群岛国家佛得角的一个岛屿上的海滩垃圾。在圣文森特的五片海滩上，沿着横断面收集垃圾，并根据 OSPAR 协议进行分类，使用矩阵评分技术将其分配到四个来源。圣文森特的海滩垃圾在数量和组成上变化很大，而陆地和海洋来源对垃圾负荷的贡献程度取决于海滩的使用和地理位置。在所调查的五片海滩中，有四片的垃圾负荷与先前描述的其他大洋岛屿的污染水平相似，而一片东北向的海滩的垃圾负荷则异常高。这可能是因为它受到主要海洋表面流的影响，从远处接收垃圾。
