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). 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.
对雅加达大都市区古红树林保护区穆阿拉安格克野生动物保护区的微塑料丰度及其特征进行了调查，为国家海洋微塑料数据清单做出了贡献。所有站点都发现了微塑料，平均每公斤干沉积物（n kg）中有 28.09 ± 10.28 个颗粒。外红树林区的沉积物比内区含有更多的微塑料。所有样本中，泡沫形式最为突出，在外区更为丰富。超过一半的微塑料粒径<1000 μm，近 50%为聚苯乙烯。这种聚合物广泛用于食品包装，容易破碎。聚丙烯和聚乙烯占微塑料的另外 50%，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，这个微塑料数据集可能是该国其他红树林的基准。
