Plastic pollution, particularly from microplastics (MPs) and nanoplastics (NPs), has become a critical environmental health concern due to their widespread distribution, persistence, potential toxicity. MPs NPs originate primary sources, such as cosmetic microspheres or synthetic fibers, secondary fragmentation of larger plastics through degradation. These particles, typically less than 5 mm, are found globally, deep seabeds human tissues, known adsorb release harmful pollutants, exacerbating ecological risks. Effective detection quantification essential for understanding mitigating impacts. Current analytical methods include physical chemical techniques. Physical methods, optical electron microscopy, provide morphological details but often lack specificity time-intensive. Chemical analyses, Fourier transform infrared (FTIR) Raman spectroscopy, offer molecular face challenges with smaller particle sizes complex matrices. Thermal including pyrolysis gas chromatography–mass spectrometry (Py-GC-MS), compositional insights destructive limited in analysis. Emerging (bio)sensing technologies show promise addressing these challenges. Electrochemical biosensors cost-effective, portable, sensitive platforms, leveraging principles voltammetry impedance detect adsorbed pollutants.

Occurrence of microplastics in Russell’s snapper (Lutjanus russellii) and associated prey species in the Central Gulf of Thailand

Environmental Science and Pollution Research, Journal Year: 2025, Volume and Issue: unknown

Abstract Microplastic (MP) contamination in fish may occur via their feeding behavior and ingestion of contaminated prey. This study investigated the presence MPs predator Lutjanus russellii (Russell’s snapper) its prey along Chumphon coast Central Gulf Thailand. Stomach contents L . were analyzed to identify species. Prey species then sampled from same geographical area as specimens for subsequent MP analysis. The dietary habits classify it a generalist carnivore, consuming diverse range food items, including zooplankton, crustaceans, small fish. No significant correlation was observed between abundance weight or length (general linear model, p > 0.05). Black red fibers predominant types both prey, though sizes varied among In stomachs, most common polymers acrylonitrile butadiene styrene (ABS; 26.32%), polyethylene terephthalate (PET; 21.05%), polyester (PES; 10.53%). Conversely, samples dominated by PES (17.58%), PET (15.38%), ABS (13.19%). Notably, similarities characteristics (shape, color, average size, certain polymer types) Portunus sp. detection smaller compared (Mann–Whitney U -test, ≤ 0.05) suggests transfer through hard-shelled crustacean underscores importance examining predator–prey interactions better understand pathways marine ecosystems, particularly regions like Thailand, where plastic pollution is prevalent. Further research required assess long-term ecological implications within chains.
