Ubiquity of microplastics in coastal seafloor sediments
Researchers applied a novel method to quantify microplastic concentrations in seafloor sediments from 42 coastal sites across southeastern Australia. They found microplastics in all samples at an average concentration of 3.4 particles per milliliter of sediment, predominantly as filaments. The study demonstrates that microplastic contamination of coastal seafloor sediments is ubiquitous and that hydrological and sediment properties influence deposition patterns.

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.
Small microplastic particles (S-MPPs) in sediments of mangrove ecosystem on the northern coast of the Persian Gulf
Small microplastic particles were documented in mangrove ecosystem sediments along the northern Persian Gulf coast, with polymer types and contamination levels reflecting regional plastic use and ocean current transport patterns. The study adds to evidence that mangrove sediments in the Middle East are accumulating microplastic pollution, threatening these ecologically important coastal habitats.
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.
Marine Plastic Pollution in Waters around Australia: Characteristics, Concentrations, and Pathways
Researchers characterized marine plastic pollution in Australian waters using surface net tows and particle-tracking models. They found an average concentration of about 4,256 plastic pieces per square kilometer at the surface, predominantly small polyethylene and polypropylene fragments with a median size of 2.8 mm, at levels comparable to the Caribbean Sea but lower than subtropical gyres.
Catchment characteristics and land-use influence on microplastics distribution in freshwater sediments
A study of three urban creeks in Brisbane, Australia found microplastic levels up to 4,400 particles per kilogram of sediment, with concentrations highest at downstream and estuary sites in urbanized zones. Polyethylene, polypropylene, and acrylic (PMMA) were the dominant plastic types, pointing to consumer products and stormwater runoff as key local pollution sources.
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.
Microplastic Pollution in Deep-Sea Sediments From the Great Australian Bight
Deep-sea sediment cores from the Great Australian Bight (1,655–3,062 m depth) were analyzed for microplastics using fluorescent dye staining, finding MP contamination at all six sampling locations — extending evidence of microplastic pollution to remote Australian deep-sea environments.
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.

Type and Distribution of Microplastics in Beach Sediment along the Coast of the Eastern Gulf of Thailand
Researchers examined microplastic distribution in beach sediments along the eastern Gulf of Thailand across two monsoon seasons, finding up to 1,698 pieces/m2 at the most contaminated site with PET (39.6%) and polyamide (22.8%) as the dominant polymer types among 17 identified.
Marine Macro- and Micro Plastic Litter on Beach Sediment of Northern Peninsular Malaysia
A survey of beaches on Malaysia's northern Peninsular coast found abundant macro- and microplastic litter in sediments, with a correlation between the amount of macroplastic debris and microplastic concentration in the same area. The findings suggest that reducing visible plastic litter on beaches would also reduce the microplastic load accumulating in coastal sediments, where it can persist and affect marine organisms for decades.
