Abstract
While interest in emerging pollutants like micro/nanoplastics (MNP) and per/polyfluoroalkyl substances (PFAS) has been growing over recent years, both MNP and PFAS present major challenges for both indoor and outdoor air quality measurements. Despite the growing body of evidence for various environmental and human health issues related to this broad set of chemical compounds, many questions remain regarding atmospheric sources and concentrations, as well as chemical processing during atmospheric transport, which likely control their ultimate impact. Here we present data collected with a High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS) and Scanning Mobility Particle Sizer (SMPS) for in-laboratory polytetrafluoroethylene (PTFE) nanoparticle calibrations and discuss these results in the context of air measurements collected in New York State.
