📢 Towards a ‘theory of change’ for ocean plastics: a socio-oceanography approach 🤝 Working with diverse communities is vital to understand & address global #plasticpollution And for inclusive, unbiased, representative, accessible research microplastics.springeropen.com/articles/10....

Towards a ‘theory of change’ for ocean plastics: a socio-oceanography approach to the global challenge of plastic pollution - Microplastics and Nanoplastics
Socio-oceanography is an emerging field which mobilises insights from natural and social sciences to explore the inter-connectedness of societal relationships with the ocean and to adopt a holistic approach to solving key oceanographic and societal challenges. 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 transferred or alternatively extracted 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. Graphical Abstract

Photoaging of Terrestrial #PlasticPollution: A Process Affected by Precipitation pubs.acs.org/doi/10.1021/...

Photoaging of Terrestrial Plastic Pollution: A Process Affected by Precipitation
Rainwater is the primary water source with which terrestrial plastic pollutants interact. Not only could active substances in rainwater generate additional reactive oxygen species but water could also react with the photoaging intermediates of plastic. Precipitation and evaporation lead to repeated shifts between the solid–liquid and solid–gas interfaces during photoaging. To investigate the impact of these interfaces on photoaging, polyvinyl chloride, polypropylene, polystyrene, and polyethylene microplastics were exposed to UVA, UVB, or UVC radiation in common rainwater (CR), rainwater residue (RR), or rainwater-free (RF) treatments. Seasonal field exposure to the corresponding commercial plastics was also conducted. FT-IR spectroscopy was utilized to analyze the chemical changes in both microplastics and commercial plastics. Compared with RF and RR, CR exposure advanced the relative time of carbonyl production in the photoaging process. A model based on local precipitation and radiation data successfully predicted the carbonyl index of field-exposed commercial plastics and highlighted the importance of alternating interface transitions. The increase in the carbonyl index due to each wet–dry cycle was 1.013–5.460 times greater than that of plastics not exposed to rainwater. These findings indicate that plastics undergo different photochemical reactions on different interfaces, and alternating interface transitions can accelerate the photoaging of plastic.
