ClearAutomatic microplastic classification using dual-modality spectral and image data for enhanced accuracy
A dual-modality classification system combining FTIR spectral data and microscope images achieved 99% accuracy in automatically identifying five common microplastic polymer types. The study deployed a web application (MPsSpecClassify) that enables researchers to efficiently classify microplastics, addressing the time-consuming and error-prone nature of manual spectral analysis.
Microplastic Abundance in Blood Cockles and Shrimps from Fishery Market, Songkhla Province, Southern Thailand
Microplastics were detected in blood cockles and shrimps purchased from a fishery market in Songkhla Province, southern Thailand, with contamination levels and polymer types characterized in commercially important seafood that represents a route of microplastic ingestion for local consumers.
Laboratoty Experiment on Copper and Lead Adsorption Ability of Microplastics
Researchers conducted a 7-day laboratory experiment examining the adsorption of copper and lead onto microplastic fragments derived from plastic straws and grocery bags in spiked seawater, finding both plastics adsorbed both metals with increasing concentrations over time. Plastic bag fragments adsorbed more of both metals than straw fragments, likely due to higher surface area, confirming the vector role of microplastics for heavy metal transport in marine systems.
Pollution Load and Transport Dynamics Govern Microplastic Export from Subtropical Estuaries
Researchers used pyrolysis-GC/MS and settling velocity experiments to characterize microplastic concentrations and transport dynamics across Gulf of America estuaries, finding that Galveston Bay had the highest polymer loads and that estuaries act as semipermeable filters — intermittently trapping and tide-modulated exporting microplastics to coastal waters — with polymer properties and hydrodynamic forcing jointly governing retention and export.
Rapid and Sensitive Quantification of Nano- and Microplastics in Water, Sediment, and Biological Tissue by Pyrolysis-Gas Chromatography Tandem Mass Spectrometry with Dynamic Reaction Monitoring
Researchers developed a highly sensitive pyrolysis gas chromatography-triple quadrupole mass spectrometry (Py-GC-qQq-MS) method using dynamic multiple reaction monitoring to quantify 12 common plastic polymers in water, sediments, and biological tissues at nanogram levels. The method achieved quantification of nano- and microplastics across diverse matrices with high specificity, using matrix-specific sample preparation including enzymatic digestion and pressurized liquid extraction.
Assessment of microplastic pollution in corals, seawater, and marine sediments in the Gulf of Thailand
Researchers assessed microplastic occurrence, abundance, and characteristics in coral, seawater, and sediment samples from two reef sites in the Gulf of Thailand, detecting microplastics in all coral samples at concentrations ranging from 0.24 to 2.60 particles per gram and finding spatial variability across reef species and sites.
Sedimentary History of Trace Metals Over the Past Half-Century in Songkhla Lake, Western Coast of the Gulf of Thailand: Anthropogenic Impacts and Contamination Assessment
This study analyzed trace metal accumulation in sediment cores from Songkhla Lake in Thailand over the past 50 years, finding increasing anthropogenic contamination linked to industrial and urban development. Heavy metals often co-occur with microplastics in sediments, and both accumulate in similar environments.
