2025 Research Triangle Environmental Health Collaborative Summit on local solutions to a global problem: Microplastics in North Carolina

Abstract

Microplastics are smaller than 5 micrometers (µm) and originate either from intentional manufacturing at that size (primary microplastics: personal care products, paints, glitter, etc.) or from the fragmentation of larger plastics in use or after disposal (secondary microplastics). The recent discovery of microplastics in various biological systems, including human bodies, raises critical questions about long-term effects in ecosystem health and human well-being.
The exponential rise in plastic and microplastic pollution set the stage for this 2-day meeting to explore the current state of knowledge regarding the source and fate of microplastics, with a focus on environmental and human health impacts in North Carolina. The goal was to highlight (1) recent research in microplastic and plastic pollution and (2) actionable steps North Carolina can take to address these problems through integration in research, changes to manufacturing and procurement processes, and evidence-informed policy.
