Rivers are one of the main pollution routes to the ocean. This study examines the source of microplastics (MPs) in Jakarta Bay based on their characteristics and estimates MPs emissions from 9 estuaries around Jakarta Bay in 3 administrative areas (Tangerang, North Jakarta, and Bekasi). The sample used was the water's surface taken using a round net. The highest abundance was found in the Dadap River, and the lowest was in the Angke River. The characteristics of the MPs are dominated by fragments, the size of 300-500 μm, and composed of polyethylene. It shows that the MPs originate from the fragmentation of residents' plastic waste that has been in the waters for a quite long time. The nine estuaries also showed a high contribution to MPs in Jakarta Bay: from North Jakarta > Tangerang > Bekasi. The emission is highly correlated with water discharge and MPs' particles in each estuary.
河流是海洋污染的主要途径之一。本研究根据微塑料（MPs）的特征，考察了雅加达湾的污染源，并估算了雅加达湾 3 个行政区（万丹、北雅加达和勿加泗）的 9 个河口的 MPs 排放量。使用圆形网采集水面样本。Dadap 河的 MPs 丰度最高，Angke 河的 MPs 丰度最低。MPs 的特征主要是碎片，尺寸为 300-500μm，由聚乙烯组成。这表明 MPs 来源于居民塑料废物在水中长时间破碎产生的。9 个河口对雅加达湾 MPs 的贡献也很高：北雅加达>万丹>勿加泗。排放与每个河口的水流量和 MPs 颗粒高度相关。
