EcoExposure™ Part II: Smartphone Polymer Typing for Scalable Plastic Monitoring
Summary
Researchers proposed a two-layer smartphone-based monitoring framework for microplastics in which total burden screening and polymer-specific classification operate as complementary rather than competing functions, outlining a roadmap for decentralized field identification of plastic types without laboratory instrumentation.
Microplastic and nanoplastic (MP/NP) monitoring is often framed as a choice between total burden measurement and polymer-specific identification. In practice, both functions are valuable and complementary. This perspective outlines Part II of a dual-path monitoring framework that has long been part of the EcoExposure™ platform roadmap: a portable smartphone-enabled pathway for polymer-specific classification. Part I focuses on scalable total burden measurement for broad screening, exposure tracking, and decentralized monitoring. Part II will aim to add higher-resolution insight regarding likely plastic types in field and consumer settings. The central argument is that burden-first and typing-second are not competing strategies; they are sequential and synergistic layers of a complete monitoring ecosystem.
