The daily accumulation rates, composition, sizes and potential sources of marine litter collected on a remote island within the Western Indian Ocean were investigated. In total, 9119 items of marine litter were collected during 40 surveys, which equated to 0.0082 items·m·d. Between 2003 and 2019 there was a significant increase in the amount of litter deposited, with the highest daily accumulation rate recorded in 2019 (0.0255 items·m·year). All specific litter types increased over time and also differed significantly in their accumulation rates, with polystyrene fragments/pieces (0.00249 items·m·d), plastic items (0.00135 items·m·d) and plastic bottles (0.0011 items·m·d) being the most commonly encountered during this study. The majority of the litter found was ≤5 cm in size. Nearly all (>80%) litter collected was made of or contained some form of plastic. Recommendations for improved management of litter and the importance of establishing regular beach clean-ups within the Seychelles are briefly discussed.
在西印度洋的一个偏远岛屿上，研究了收集到的海洋垃圾的日积累率、组成、大小和潜在来源。在 40 次调查中，共收集到 9119 件海洋垃圾，相当于 0.0082 件·米·天。2003 年至 2019 年，沉积的垃圾量显著增加，2019 年记录到的日积累率最高（0.0255 件·米·年）。所有特定类型的垃圾都随着时间的推移而增加，其积累率也有显著差异，其中聚苯乙烯碎片/块（0.00249 件·米·天）、塑料物品（0.00135 件·米·天）和塑料瓶（0.0011 件·米·天）是本研究中最常见的。发现的垃圾大部分尺寸≤5 厘米。收集到的几乎所有（>80%）垃圾都是由塑料或含有某种形式的塑料制成的。简要讨论了改善垃圾管理的建议以及在塞舌尔定期进行海滩清理的重要性。
