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.

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.

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.
