ClearThe form and distribution of microplastic in sediment and water columns of Manado Bay, North Sulawesi
Microplastics were detected in both water and sediment samples from Manado Bay in North Sulawesi, Indonesia, with a variety of shapes including fragments, fibers, and pellets. The contamination reflected inputs from land-based plastic waste and coastal activities. The study documents the extent of microplastic pollution in an Indonesian coastal bay and highlights risks to local marine ecosystems.
Microplastic Distribution in Sediments in Coastal of Pariaman City, West Sumatera Province
Indonesian researchers surveyed microplastic distribution in sediments along the coast of Pariaman City, West Sumatra, finding plastic particles throughout the study area. Higher concentrations near tourism areas and residential zones suggest that local human activities are the primary sources of coastal microplastic contamination.
The abundance of Plastic Marine Debris on Beaches in Ambon Bay
Researchers measured plastic marine debris — including large microplastics, mesoplastics, and macroplastics — on two beaches in Ambon Bay, Indonesia. The study provides baseline data on plastic pollution levels in a region with growing coastal populations and limited plastic waste management infrastructure.
Occurrence and distribution of microplastics in the beach sediment of Anday Beach, West Papua (Indonesia)
Researchers measured microplastic occurrence and distribution in beach sediments at Anday Beach in West Papua, Indonesia, finding microplastics present across sampling sites. The findings document plastic contamination reaching a relatively remote Indonesian coastal area.
Distribution and Types of Microplastics in Coastal Sediments of Sepanjang Beach
Researchers characterised the distribution and types of microplastics in coastal sediments of Sepanjang Beach, Indonesia, examining microplastic presence in relation to gastropod digestive tract contamination in the local marine environment.
Baseline assessment of microplastics pollution in beach sediments along tropical coastline (Kuala Langat, Malaysia)
Researchers conducted baseline assessments of microplastic pollution in beach sediments along tropical coastlines, documenting particle abundance, morphology, and polymer composition at sites with varying levels of human activity to establish reference conditions.
Identification of Microplastics in The Outer Ambon Bay, Mollucas
Researchers identified and quantified microplastic accumulation in water and sediments from Outer Ambon Bay, Maluku, finding that plastic debris fragmented by physical and chemical factors had accumulated in the water column and sediments with potential for ingestion by marine biota.
Distribution and types of microplastics on the coast of Aipiri and Andai Beaches, Manokwari District, Indonesia
Researchers surveyed two beaches in Manokwari District, Indonesia, finding microplastics distributed across both sites with fragments and films as the dominant types, raising concern about plastic pollution entering coastal marine ecosystems in this biodiversity-rich region.
Spatial Distribution and Quantification of Microplastic Contamination in Sediments of Kaliratu Coastal Waters, Kebumen, Indonesia
Researchers found microplastics in sediments along Kaliratu Beach in Indonesia at concentrations of 25–57.5 particles/kg, with fibres, fragments, films, and pellets all present, and used hydrodynamic modelling to trace how seasonal monsoon currents distribute them along the coastline. The findings highlight that even relatively remote Indonesian coastal areas near shrimp ponds and other anthropogenic activity are accumulating measurable plastic pollution.
Microplastic abundance and distribution in surface water and sediment collected from the coastal area
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.
Identifikasi Mikroplastik Pada Sedimen di Pulau Perak, Jakarta Indonesia
Researchers identified and characterised microplastics in sediments at Perak Island, Jakarta, Indonesia, examining the shapes, sizes, and composition of plastic particles smaller than 5 mm that accumulate in coastal sediment environments.
Identification, Abundance, and Chemical Characterization of Macro-, Meso-, and Microplastics in the Intertidal Zone Sediments of Two Selected Beaches in Sabah, Malaysia
Researchers identified and characterized macro-, meso-, and microplastics in intertidal sediments of two beaches in Sabah, Malaysia, finding significant plastic contamination with heavy metal associations that pose potential ecological risks to coastal environments.
Risk Assessment of Microplastic Exposure in the Marine Sediment of Southern Central Waters of Vietnam
Researchers collected sediment samples from 14 sites in southern central Vietnamese coastal waters and detected microplastics at all locations (100–1,350 MPs/kg), identifying fibers and fragments as the dominant forms and nine polymer types, providing the first microplastic baseline for this region.
Spatial distribution and characteristics of microplastic particles in sediments at Belawan Estuary, North Sumatra Province
Researchers characterized the spatial distribution and properties of microplastic particles in sediments at Belawan Estuary in North Sumatra, Indonesia, providing baseline data on microplastic abundance, morphology, color, and polymer composition at a site with no prior microplastic research to inform future ecological assessments of this estuarine system.
Plastic pollution in Moreton Bay sediments, Southeast Queensland, Australia.
Plastic contamination was documented in sediments of Moreton Bay in southeast Queensland, Australia, with multiple polymer types detected across the bay. The study fills a knowledge gap about the type and distribution of plastic pollution in Australian coastal sediments, which can affect bottom-dwelling organisms and local seafood.
Contamination and characterization of microplastics in different sediments of the river estuaries (the inner Gulf of Thailand)
Researchers measured microplastic contamination in river estuary sediments in the inner Gulf of Thailand, finding widespread contamination at all sites. The study characterizes the types and abundance of microplastics in a highly trafficked coastal region of Southeast Asia.
The presence of microplastics in Surabaya coastal area and its correlation with conventional water quality parameters
Researchers measured microplastic presence in coastal waters of Surabaya, Indonesia, and examined correlations with marine biodiversity indicators. Elevated microplastic concentrations were associated with reduced diversity of benthic organisms at contaminated sites.
Microplastic Pollution in Indonesia: The Contribution of Human Activity to the Abundance of Microplastics
This systematic review of Indonesian microplastic research found that coastal and marine sediments have the highest microplastic abundances, driven by widespread use of cheap single-use plastics and poor waste management across urban and rural areas.
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.
