Abstract

Microplastics are found in Earth's atmosphere, lithosphere, hydrosphere, pedosphere, and ecosphere. While there is a growing interest and need to solve this grand challenge in both the academic and policy realms, few have engaged with academics, policymakers, and community partners to co-identify the problem, co-design research, and co-produce knowledge in tackling this issue. Using a convergence research framework, we investigated the perception of microplastic pollution among different end users, delivered educational materials to K-12 teachers and practitioners, and identified key sampling points for assessing environmental microplastic concentrations in the Columbia River Basin, United States. Three community partner workshops identified regional issues and concerns associated with microplastic pollution and explored potential policy intervention strategies. The stakeholder survey, co-designed with community partners, identified varying perceptions around microplastic pollution across educators, government employees, non-profit employees, and industry practitioners. Pre- and post-test results of teacher workshops show increases in participants' knowledge after taking a four-week summer class with the knowledge being translated to their students. Community partners also helped develop a unique passive sampling plan for atmospheric deposition of microplastics using synoptic moss samples and provided freshwater samples for microplastic quantification across the basin. Our study drew three major lessons for successfully conducting convergence environmental research—(1) communication and trust building, supported by the use of key-informants to expand networks; (2) co-creation through collaboration, where partners and students shaped research and education to enhance impact; and (3) change-making, as project insights were translated into policy discussions, community outreach, and classrooms.
