An investigation of microplastic abundance and its characteristics was conducted in Muara Angke Wildlife Reserve, a relic mangrove forest in the Jakarta metropolitan, to contribute to marine microplastics' national data inventory. Microplastics were found in all the stations, with an average of 28.09 ± 10.28 particles per kg of dry sediment (n kg⁻¹). Sediments in the outside mangrove area contained more microplastics than the inside area. Foam form was the most dominant in all the samples and was found more abundant on the outside. More than half of microplastics were of size <1000 μm, and nearly 50% were polystyrenes. This polymer is widely used for food packaging, which is prone to be fragmented. Polypropylene and polyethylene form another 50% of microplastics, which are widely used for textiles and fishing gears. As Jakarta is the largest city in Indonesia, this microplastic dataset may be the benchmark for other mangroves around the country.

在雅加达都会区的一片红树林Muara Angke野生动物保护区进行了微塑性丰度及其特征的调查，以帮助海洋微塑性的国家数据清单。在所有站点中都发现了微塑料，每千克干沉积物中平均含有28.09±10.28个颗粒（n kg ^-1）。红树林外部区域的沉积物比内部区域含有更多的微塑料。在所有样品中，泡沫形式是最主要的，并且在外部发现更为丰富。超过一半的微塑料尺寸小于1000μm，近50％是聚苯乙烯。该聚合物广泛用于食品包装，容易碎裂。聚丙烯和聚乙烯占微塑料的50％，它们被广泛用于纺织品和渔具。由于雅加达是印度尼西亚最大的城市，该微塑料数据集可能是该国其他红树林的基准。
