Abstract

Lifelong exposure history (exposome) of particulate matters (PMs) is essential for understanding environmentally induced health risk, however, diversities in PM size, shape and components are a technical barrier to track the exposome. Previously, we reported a PM sensor utilizing water film-based collection and microfluidics-employed ionic current measurement at MicroTAS 2018 [1], which was only applied to analyze non-soluble PMs. Herein, we realized a potentiometry-based methodology for sensing multiple ion components derived from water-soluble PMs via arrayed ion-selective electrodes (ISEs). NO3-, NH3+, and Na+ ions extracted from a real PM sample were simultaneously detected and analyzing their contents was achieved.
