Spatial–Vertical Distribution of Microplastics Abundance and Characteristics in the Coastal Waters of Raha City, Muna Regency
Researchers mapped the spatial and vertical distribution of microplastics in the coastal waters of Raha City, Indonesia, sampling at three stations representing different human activity levels. The harbor area showed the highest microplastic abundance, and concentrations were generally higher at the surface and mid-water layers than near the bottom. The study confirms that fisheries and harbor activities, along with river-carried waste, are major sources of microplastic pollution in these coastal waters.
Analisis Cemaran Mikroplastik Di Pesisir Teluk Palu, Sulawesi Tengah
This study measured microplastic contamination in the surface water, water column, and sediments of Palu Bay, Central Sulawesi, Indonesia. Microplastic concentrations were found across all sampled depths, with fibers being the most common type. The results indicate that coastal urbanization is contributing to significant microplastic accumulation in this Indonesian bay.
A Comparative Assessment of Microplastic Abundance in Conservation vs. Residential Coastal Sediments in Bitung, North Sulawesi Indonesia
Researchers compared microplastic abundance in coastal sediments at a nature reserve versus an industrial port in Bitung, North Sulawesi, finding significantly higher levels at the industrial site and raising concerns about plastic intrusion into protected areas.
Microplastic pollution along the coastal island shorelines of Bangladesh: Distribution, patterns, and abundance
This study characterized microplastic pollution on coastal island shorelines of Bangladesh, measuring particle abundance, types, shapes, and polymer composition across sites with different human use intensities. Tourist and fishing beaches showed the highest contamination, with fishing-related plastics dominating.
Linking the Tourism Activity to the Occurrence and Distribution of Microplastics
Researchers assessed microplastic abundance, type, and spatial distribution in coastal water, sediments, and fish across three zones of Gili Trawangan, Indonesia, finding that tourism-related activities concentrated microplastics at recreational beaches with concentrations reaching 19.25 particles/L.
Distribution and mitigation efforts for microplastic pollution in Kendari bay as the mainstay coastal tourism area of Southeast Sulawesi
This study mapped the distribution of microplastic pollution in Kendari Bay in Indonesia and evaluated mitigation options. The bay, which serves as a tourism hub, showed significant plastic contamination, with debris concentrated in areas closest to urban and fishing activities.
Abundance and Characteristics of Microplastics in Coastal Sediment and Seawater Collected from Surabaya and Tulungagung
Microplastic abundance in seawater and coastal sediments from two East Java sites differed significantly — Surabaya (north coast) showed 2,100 particles/m³ in water vs. 170 particles/m³ in Tulungagung (south coast) — with fragment and fiber types dominant at both sites.
Abundance and Types of Microplastics in the Water of Sukaraja
Researchers quantified microplastic abundance and types in the coastal waters of Sukaraja, Indonesia, using random sampling at three stations during high and low tide in April 2021. A total of 3,600 particles/m3 were recorded, with fragments being the most abundant type (1,466 particles/m3) and film the least, with the highest concentrations near the main plastic waste accumulation zone.
Abundance and Characteristics of Microplastics Found in The Gastrointestinal Tract of Commercial Marine Fish from Bitung, North Sulawesi, Indonesia
Researchers analyzed microplastic abundance and characteristics in the gastrointestinal tracts of commercial marine fish from Bitung, North Sulawesi, Indonesia, providing the first data on seafood microplastic contamination from one of the country's major fisheries production centers.
Morphometric characteristics and spatiotemporal heterogeneity of microplastics on the north-east coast of India
Survey of surface waters along the northeast coast of India found microplastics present in all sampled water masses, with higher concentrations during the monsoon season than the post-monsoon period, and fragments and fibers making up the vast majority of particles. The seasonal pattern suggests land-based runoff is a major delivery pathway, with implications for the many coastal communities in the region that depend on these waters for fishing and livelihoods.
Abundance and characteristics of microplastics in the northern coastal waters of Surabaya, Indonesia
Microplastics were characterized in coastal waters off Surabaya, Indonesia, with fibers as the most common shape and polyethylene terephthalate as the dominant polymer, reflecting textile and packaging waste inputs to the region.
