Abstract

Abstract: Plastic pollution in the ocean primarily originates from the land-derived mismanaged plastic waste that is transported by rivers. This study aimed to estimate the plastic litter generation in the surface water in Jakarta and Indonesia. A field survey was conducted at six riverine sampling points (upstream to downstream) and three holding facilities of the litter in Jakarta during the rainy season. The Jakarta Open Data database was used to estimate the tonnage of plastic litter. By mass, plastic comprised approximately 74 % of the anthropogenic litter in rivers and 87 % in holding facilities. The riverine plastic proportion slightly increased downstream. Approximately 9.9 g/person/day of plastic litter was discharged into Jakarta's surface water during rainy season and recovered by floating booms. To reduce plastic pollution and its severe impacts on aquatic ecosystems and human health, further field investigation is necessary to design an effective clean-up system and litter-prevention strategy. Graphical abstract: Unlabelled Image Highlights: Plastic comprised 74 % of riverine anthropogenic litter by dried-mass. Plastic proportion slightly increased downstream. The holding facilities had a higher plastic proportion (87 %) than rivers. Plastic litter recovered from floating net boom was up to 205 kg/day. Plastic leakage into the surface water was 9.86 g/person/day in the rainy season.
