It is within this specific context that we explore and reflect upon diverse communities in relation to engaging with plastic pollution in the ocean, one of the foremost socio-environmental challenges of our time. We establish definitions of 'community', arguing that communities are not 'out there' waiting to be engaged with but are dynamic and (re)constituted in four key contexts - geographical, practical, virtual, and circumstantial. We outline some 'rules of engagement' and draw upon several international case studies in the context of plastic pollution to evidence and emphasise the value of working with members of diverse communities to better address socio-oceanographic challenges. In the context of plastic pollution, communities have a vital role to play in terms of co-creating knowledge, lived experience, diverse expertise, and agency to bring about social change. Given the ubiquity of plastics in our day-to-day lives, and subsequently as an environmental pollutant, no community is unaffected by this issue. Relating to socio-oceanography, we argue that structural power imbalances in terms of how diverse communities and natural scientists are traditionally positioned within academic research mean that 'formal' scientific knowledge is frequently privileged, and members of communities risk being positioned as 'empty vessels'. Moving away from this 'deficit' model where knowledge is simply <i>transferred</i> or alternatively <i>extracted</i> from communities allows us to progress towards an inclusive 'socio-oceanography in society' approach, where members of communities are valued as vital in prioritising and addressing socio-oceanography issues which affect everyday life. Accessibility, openness, ethics and fairness in data are also essential in ensuring that research outcomes can be applied widely outside the academic community.</p><p><strong>Graphical abstract: </strong></p>","PeriodicalId":74190,"journal":{"name":"Microplastics and nanoplastics","volume":"5 1","pages":"20"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12075391/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144082599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated the toxicity of a broad size range of amorphous MNPs generated from different environmentally-relevant polymers.</p><p><strong>Methods: </strong>Bronchial epithelial cells (BEAS-2B) were exposed to three different doses of polyvinylchloride (PVC), polypropylene (PP), or polyamide (PA) particles (< 1 μm-10 μm), as well as leachates from these polymers. Toxicity was evaluated by assessment of cytotoxicity, inflammation (IL-8 release and inflammatory gene expression) and oxidative stress (DCFH-DA assay and antioxidant gene expression). Furthermore, the molecular mechanism behind MNP-induced inflammation was investigated by studying activation of two well-known inflammation related transcriptional factors (NF-κB and AP-1).</p><p><strong>Results: </strong>Only PA nanoplastics induced significant cell death, IL-8 secretion and inflammatory gene expression compared to vehicle control. PA-induced inflammation was accompanied by NF-κB, but not AP-1, transcriptional activity. PA did not increase cellular ROS levels; however, it did lead to increased expression of the antioxidant gene superoxide dismutase 2. In addition to PA, exposure to < 1 µm and 1-5 µm PP particles resulted in elevated IL-8 secretion, likely due to the presence of talc added as filler. None of the leachates affected cytotoxicity or inflammation.</p><p><strong>Conclusion: </strong>Toxicity of MNPs to human bronchial epithelial cells was dependent on polymer type, size and dose. Nanoplastics, especially PA, were more toxic to bronchial epithelial cells than microplastics and induced cytotoxicity and an inflammatory response.</p><p><strong>Graphical abstract: </strong></p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1186/s43591-025-00126-9.</p>","PeriodicalId":74190,"journal":{"name":"Microplastics and nanoplastics","volume":"5 1","pages":"19"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12081513/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144095850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
