Analysis of types, forms and abundance of microplastics in the mangrove forest area of pusong island, langsa city
Summary
Researchers analyzed the presence, morphology, and abundance of microplastics in water and sediment samples from the mangrove forest area of Pusong Island, Langsa City, Aceh, Indonesia. They found microplastics in the fragment and fiber forms at densities of 7-13 particles per liter with an average size of 200 micrometers, documenting pollution in a sensitive coastal ecosystem.
Pollution of mangrove waters by microplastic particles is coastal plastic waste pollution which has become a major water pollution problem in developing countries. However, this pollution problem, both qualitatively and quantitatively, has not yet been discussed comprehensively. Therefore, it is necessary to analyse the level of microplastic presence and identify the types of microplastics of each size found in the water in the mangrove forest area of Langsa City-Aceh. The aim of this research is to analyse the presence, shape and dominance of microplastic particles in the mangrove waters of Langsa City. The research method was carried out by taking water and river sediment samples based on SNI 03-7016-2004 and the samples were the result of a combination of places (integrated samples). Separation of microplastics is carried out by filtering, destroying organic compounds, separating based on specific gravity and filtering using vacuum. Identification of the type, shape and abundance of microplastics is carried out using a microscope. The analysis results show that microplastics in water are generally of the fragment and fibre type with a density of between 7 - 13 particles per Liter with an average size of 200 µm.

ACCUMULATION OF MICROPLASTICS (<300 µM) IN MANGROVE SEDIMENTS OF BANDA ACEH CITY, INDONESIA
Researchers measured microplastic accumulation in mangrove sediments in Banda Aceh, Indonesia, finding up to 3,840 particles per kilogram of sediment — with plastic pellets and fibers smaller than 300 micrometers being the most common types — suggesting these coastal ecosystems are acting as significant traps for plastic pollution from nearby land and waterways.
Microplastics contamination of sea surface water in Banda Aceh City and Aceh Besar District, Aceh Province, Indonesia
Researchers analyzed microplastic contamination in sea surface waters of Banda Aceh City and Aceh Besar District along the coast of Aceh Province, Indonesia, where plastic waste from urban areas degrades into microparticles threatening coastal water quality. The study quantified microplastic concentrations and characterized particle types in surface water samples from this Indonesian coastal region.
Characteristics and distribution of microplastics in the coastal mangrove sediments of China
A survey of mangrove sediments along China's coast found microplastics were ubiquitous, with concentrations and polymer types varying by proximity to human activity and hydrological conditions. The study shows that mangrove forests, which provide critical coastal ecosystem services, are accumulating significant quantities of plastic pollution.
Abundance of Microplastics in Mangrove Sediments on Pari Island, Jakarta Bay, Indonesia
Researchers sampled mangrove sediments on Pari Island in Jakarta Bay in two seasons and identified microplastics by shape, color, size, and polymer type, finding that seasonal variation affected abundance and distribution. The study documents microplastic accumulation in a mangrove ecosystem adjacent to the Indonesian capital.
Microplastics Characteristics in Water and Sediment From Three Ecosystems on Sari Ringgung Beach, Pesawaran Regency, Lampung Province
Researchers sampled water and sediment across mangrove, seagrass, and coral reef ecosystems at an Indonesian beach, finding microplastic contamination in all three habitats with the mangrove ecosystem showing the highest concentrations — up to 467 particles per kilogram of sediment. Fibers, films, and fragments smaller than 1 mm were the most common forms found, highlighting widespread microplastic pollution across multiple coastal ecosystem types.
