Microplastic profile in the sediment of Jakarta Bay estuary, Indonesia: Characterization based on size fraction and the potential risk to the ecosystem

Characterisation and abundance of microplastic pollution in sediments of Banten Bay, Indonesia

AI summary · Read the abstract

Scientists found tiny plastic particles (mostly small fragments and fibers made of common plastics like polypropylene and polyethylene) buried in the seafloor sediment of Banten Bay, Indonesia, likely from nearby industrial and residential growth. This matters because these coastal waters are used for fishing, and microplastics in sediment can work their way up the food chain into the seafood people eat, though this study didn't directly test human health effects.

The contribution of estuaries to the abundance of microplastics in Jakarta Bay, Indonesia

AI summary · Read the abstract

Researchers found that rivers draining into Jakarta Bay are a major source of microplastics, with polyethylene fragments in the 300-500 micrometer size range dominating, and that spatial variation in abundance across nine estuaries reflects differences in local land use and waste management.

Study on macro and microplastics debris in Indonesian water: Current condition and problem

Microplastic (MP) Pollution in the Context of Occurrence, Distribution, Composition and Concentration in Surface Waters and Sediments: A Global Overview

AI summary · Read the abstract

Researchers compiled global data showing microplastic pollution is essentially everywhere — in surface waters and sediments worldwide — with some locations finding microplastics in nearly every sample collected, underscoring how pervasive this contamination has become.

Microplastic abundance and distribution in surface water and sediment collected from the coastal area

AI summary · Read the abstract

Researchers found microplastics in both surface water and sediments across 12 coastal sampling sites in Jakarta Bay, Indonesia, documenting their abundance, distribution patterns, and morphological characteristics in a heavily urbanized tropical coastal environment.
