Macro-litter accumulation surveys were carried out in six beaches in Kilifi, Mombasa and Kwale Counties. Macro litter were collected, quantified and characterized to determine their composition, distribution and accumulation rates. The results showed that the accumulation rates ranged between 1.53 ± 1.23 and 11.46 ± 7.72 (for dry zones) and 2.69 ± 2.13 and 8.93 ± 7.87 items m⁻¹ day⁻¹ (for wet zones). Plastics and foam were the most abundant litter categories. Local products constituted about 88% of all the collected litter. Food packaging products constituted about 91.3% of all branded litter types. Marine litter pollution particularly by plastics was widespread in all studied coastal counties. However, a significant amount of litter encountered in the beaches was of local origin, thus a local solution to waste management (that will eliminate leakage into marine environments) will considerably reduce marine litter pollution in Kenya.

在基利菲，蒙巴萨和夸勒县的六个海滩进行了大型垃圾堆积调查。收集，定量和表征大型垃圾以确定其组成，分布和累积速率。结果显示，累积速率介于1.53±1.23和11.46±7.72（对于干燥区域）和2.69±2.13和8.93±7.87项目m ^-1 天^-1之间（对于潮湿区域）。塑料和泡沫是最丰富的垃圾类别。本地产品约占收集的所有垃圾的88％。食品包装产品约占所有品牌垫料类型的91.3％。在所有研究的沿海县，海洋垃圾污染特别是塑料污染。但是，在海滩上遇到的大量垃圾是当地来源的，因此对废物管理的本地解决方案（将消除向海洋环境的泄漏）将大大减少肯尼亚的海洋垃圾污染。
