Plastic pollution is a widespread and growing concern due to its transformation into microplastics (MPs), which can harm organisms ecosystems. This study, aimed identify plastic in the feces of terrestrial vertebrates using convenience sampling both inside outside protected areas Western Thailand. We hypothesized that MPs are likely be detectable all vertebrate species, primarily form small black fragments. predicted varying quantities same species across different areas. Furthermore, we expected factors indicating human presence, landscape characteristics, scat weight, MP abundance water, soils, sediments would influence presence plastics feces. Among 12 studied, potential were found 41.11% 90 samples, totaling 83 pieces eight including Asian elephant ( Elephas maximus ), Eld’s deer Rucervus eldii Dhole Cuon alpinus Gaur Bos gaurus Sambar Rusa unicolor Wild boar Sus scrofa Northern red muntjac Muntiacus vaginalis Butterfly lizard Leiolepis belliana ).

The global presence of plastic litter and its accumulation in the environment has become an issue concern to public policymakers. This triggered innovators past decades design develop a multitude remediation technologies prevent from entering environment, or clean up legacy litter. study aims (i) systematically review current scientific literature on technologies, (ii) create 'plastic clean-up prevention overview' illustrating 124 29 characteristics, (iii) qualitatively analyse their key characteristics (e.g., fields application, targeted plastic), (iv) investigate challenges opportunities for inland waterways canals, rivers) ports. We identified 61 publications until June 2022. Thirty-four these studies were published within last three years, demonstrating growing interest. presented overview indicates that are, so far, preferred field with 22 specifically designed cleaning plastics waterways, 52 additional ones potential be installed locations. Given importance we highlighted strengths, weaknesses, opportunities, threats (SWOT). Our results indicate that, despite challenges, provide essential prospects, improving environmental quality raising awareness. is instrumental as it illustrates up-to-date provides comprehensive analysis phase, testing, use technologies.

Intrinsic interaction inferred oxidative stress and apoptosis by Biosurfactant-microplastic hybrid reduces coordinated in vivo biotoxicity in zebrafish (Danio rerio).

Materials Today Bio, Journal Year: 2025, Volume and Issue: 31, P. 101466 - 101466

Published: Jan. 8, 2025

The proliferation of microplastics (μP) in aquatic environments poses a significant threat to ecosystem health, with repercussions extending organisms and potentially human health. In this study, we investigated the efficacy novel biosurfactant-microplastic (BSμP) hybrid reducing vivo green bio-toxicity induced by oxidative stress apoptosis zebrafish (Danio rerio). Microplastics, ubiquitous environments, were hybridised Biosurfactant evaluate their potential mitigating effects. A stable BSμP was formed zeta -10.3 ± 1.5 mV. Exposure embryos μP resulted increased markers, including elevated levels reactive oxygen species apoptosis, as evidenced expression apoptotic markers morphological changes embryonic zebrafish. However, significantly ameliorated observed toxic effects reduced activity. This effect deduced intrinsic hybridisation, which likely mitigated bioavailability toxicity molecular interaction metabolic proteins like Sod1 p53 through less accumulation internalisation. Overall, our findings highlight promising approach for ecological impacts microplastic pollution.

Abstract Since first being introduced for public use in the 1960s, plastic has become one of most pervasive and ubiquitous forms pollution globally. The potential fate effects on birds is a rapidly growing area research, but knowledge terrestrial freshwater species limited. Birds prey have been particularly understudied, with no published data ingestion raptors Canada to date, very few studies To assess raptors, we analysed contents upper gastrointestinal tracts from total 234 individuals across 15 raptor species, collected between 2013 2021. Upper were assessed plastics anthropogenic particles > 2 mm size. Of specimens examined, only five two had evidence retained tract.

These results suggest that hunting do not appear ingest retain larger particles, though foraging guild habitat may influence risk. We recommend future research investigate microplastic accumulation order gain more holistic understanding these species. Future work should also focus increasing sample sizes all improve ability landscape- species-level factors vulnerability susceptibility ingestion.

Plastic in the form of microplastic particles (MPs) is now recognized as a major pollutant unknown consequences aquatic habitats. Mosquitoes, with eggs, larvae, and pupae, are likely to encounter microplastic, particularly those species that abundant close proximity human development, including vector animal disease. We examined effects polyethylene MPs, most common documented environmental samples, on development survival mosquitoes Aedes albopictus Culex quinquefasciatus. In laboratory egg-laying larval container environments similar used by both field, mix 1–53 µm MPs at concentrations 60, 600, 6000 MP ml−1 increased early instar mortality relative control treatments. A significant difference was found response each lowest concentration tested, Cx. quinquefasciatus equivalent conditions but Ae. larvae elevated 37% within 48 h. These results differ from previous studies which were only exposed during last stage it concluded ontogenically transferred without negatively affecting development. Increasing plastic could therefore act selective pressures ultimately influence outcomes ecological interactions among mosquito populations.

Abstract As an anthropogenic creation, plastic pollution is a form of human–wildlife interaction and emerging conservation threat to growing number species in both terrestrial marine environments. Although has spread worldwide body literature shows its effects on human health, little known about impact our closest living relatives, nonhuman primates, their habitats. With over 60% primate already under extinction, habitats poses unique problem, exposing them physical harm, synthetic chemicals, pathogens through ingestion, entanglement, oral manipulation. Moreover, presence soil, air, waterways, leads environmental degradation reduces the quality ecological functionality This perspective article covers what so far as primates. It call for primatologists address research initiatives. By collecting data pollution’s assessing primates habitats, we can develop safe protocols prevention strategies combat Anthropocene.
