Plastic pollution has become a growing concern for environmental and human health in recent years. Currently, research suggests that soil compartments might be highly contaminated, with compost being one of the major sources plastic contamination, especially at reduced sizes. In Geneva, microplastic contamination already been evaluated industrial but not yet field-side compost. Therefore, this work focuses on evaluation concentrations characterization particles (MPs) Geneva. Four different composts were sampled Geneva sieved sizes ranging from >5 mm to 0.5 mm.

Bioaccumulation and biomagnification of anthropogenic particles are crucial factors in assessing microplastic impacts to marine ecosystems. Microplastic pollution poses a significant threat iconic often endangered species but examining their tissues gut contents for contaminant analysis via lethal sampling is challenging due ethical concerns animal care restrictions. Incorporating empirical data from prey items fecal matter into models can help trace movement through food webs. In this study, the Galápagos penguin web served as an indicator assess bioaccumulation potential using trophodynamic Ecopath with Ecosim (EwE) modelling Ecotracer. Empirical collected surface seawater near colonies, zooplankton, prey, scat October 2021 were used inform ecosystem model. Multiple scenarios, including 99% elimination rate, employed model sensitivity. Model predictions revealed that microplastics bioaccumulate all predator-prey relationships, highly dependent on rate. It establishes need more research rates different plastics, which critical missing gap current ecotoxicological science. Compared data, efforts underpredicted concentrations zooplankton over-predicted fish. Ultimately, provides novel insights microplastics’ risks. These findings support regional plastic management conserve native endemic Islands Marine Reserve.

The ubiquitous and global ecological footprint arising from the rapidly increasing rates of plastic production, use, release into environment is an important modern environmental issue. Of concern are risks associated with at least 16,000 chemicals present in plastics, some which known to be toxic, may leach out both during use once exposed conditions, leading human exposure. In response, United Nations member states agreed establish international legally binding instrument on pollution, plastics treaty. resolution acknowledges that treaty should prevent pollution its related impacts, effective prevention requires consideration transboundary nature full life cycle must addressed. As a group scientific experts members Scientists' Coalition for Effective Plastics Treaty, we concur there six essential "pillars" necessary truly reduce allow chemical detoxification across plastics. These include reduction simplification, safe sustainable design chemicals, incentives change, holistic approaches alternatives, just transition equitable interventions, centering rights. There critical need scientifically informed globally harmonized information, transparency, traceability criteria protect public health. right clean, healthy, upheld, thus it crucial scientists, industry, policy makers work concert create future free hazardous contamination.

Microplastics (MPs) are emerging environmental pollutants that pose a significant threat to wildlife within forest ecosystems. However, the quantity and types of MPs in habitats remain unclear. This study is first assess distribution Amur tiger habitat northeast China. Our results showed were detected soil, water, atmosphere, forage plants, ungulate top predator feces ecosystem, respectively. The average diameter all was 44.99 ± 34.80μm. predominant polymers found samples polyamide, polyvinyl chloride, polyurethane. Certain sample shared similar MP polymer type distributions, indicating potential links their sources transfer pathways. Consequently, these findings provide some new insights on pollution problem prompt us consider how control manage conservation.
