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.

Green consumption behaviour among higher education students as an approach to achieving sustainable source reduction of marine plastic pollution

Young Consumers Insight and Ideas for Responsible Marketers, Journal Year: 2024, Volume and Issue: 25(4), P. 528 - 553

Purpose Marine plastic pollution (MPP) is increasing in recent times because of the high usage products. Green consumption behaviour (GCB) gaining attention as effective approach to achieving sustainable source reduction pollution, which negatively affects both human and marine biodiversity ecosystem. Although, Higher Education (HE) students are key stakeholders addressing environmental issues, including MPP, there limited empirical research Ghana on factors influencing HE students’ GCB. This study, an endeavour bridge gap, used revised theory planned (TPB) framework investigate higher-education green Ghanaian context. Specifically, purpose study examine interplay consumer novelty seeking (CNS), concern (EC), perceived behavioural control social influence among Ghana. The also explored moderating role gender relationship between CNS behaviour.

Research limitations/implications Although this presents results that insights policy practical implications, it has some limitations worth mentioning future directions. Firstly, participants sampled comprised only Ghana, may limit applicability other student populations various universities beyond. Moreover, exclusion non-students who considered “Generation Z” (i.e. born within 1995–2010) narrow scope generalisability context young consumers’ To enhance studies, recommended be extended. Furthermore, should noted primarily measured based self-reported data. Therefore, could adopt alternative approaches, such non-self-reported measures or experimental so reduce complexities gap exist attitudes Practical implications These policymakers, educators advocates develop targeted initiatives resonate foster practices contribute global efforts against pollution.

Abstract Microplastics (MPs) were investigated in four fish species viz., paradise threadfin ( Polynemus paradiseus ), corsula mullet Rhinomugil flathead sillago Sillaginopsis panijus ) and king gobyeel Taenioides sandwipi which collected from the Meghna River estuary Bangladesh. The gastrointestinal tracts (GITs) of fishes n = 80 total) examined for presence MPs following alkali digestion, microscopic observation μ-FTIR analysis. A total 573 detected across all species, indicating 81.3% samples. On average, there 7.16 ± 4.33 MP items/fish, 2.16 1.76 items/g GIT 0.15 0.12 body weight. Polyethylene, polypropylene nylon most abundant polymers, comprising 47%, 23% 19%, respectively, according to majority fibers (62.48%), with white being dominant color. R. demonstrated highest number < 500 μm size range, suggesting that smaller particles are more bio-available pelagic fish. findings confirm contamination by MPs, their local raises concerns about potential public health risks through food chain.
