This is the first study to evaluate the presence and distribution of microplastics in sediments in the regions with a unique degree of complexity, such as wildlife reserve areas, a Ramsar site that connects directly to Greater Jakarta's mainland, recreational islands, and a marine national park. Microplastics of varying sizes and shapes are found in all places, with an increase trend in the abundance toward areas near to the epicenter of human activity. Comparatively to other marine protected areas, the amount of microplastics discovered is comparable; however, there is an upward trend. Season influences microplastic accumulation, with the dry season causing the greater accumulation. Small-sized microplastics and microplastics resulting from large plastic fragments were predominantly discovered. The properties of microplastics in the study region are dominated by polyethylene, polypropylene, polystyrene, polyvinyl chloride, and nylon. Additional in-depth research and waste reduction from all sources that involve all stakeholders are required to reduce the amount of contaminants entering the protected area.

这是第一项评估具有独特复杂程度的地区沉积物中微塑料的存在和分布的研究，例如野生动物保护区、直接连接大雅加达大陆的拉姆萨尔湿地、休闲岛屿和海洋国家公园。各种大小和形状的微塑料随处可见，并且在靠近人类活动中心的地区其丰度呈增加趋势。与其他海洋保护区相比，发现的微塑料数量相当；然而，有上升趋势。季节影响微塑料的积累，旱季会导致更大的积累。主要发现的是小型微塑料和由大塑料碎片产生的微塑料。研究区微塑料的性质以聚乙烯、聚丙烯、聚苯乙烯、聚氯乙烯和尼龙为主。需要所有利益相关者进行额外的深入研究和减少所有来源的废物，以减少进入保护区的污染物数量。
