Summary of the PM Working Group Discussion on Submicron and Ultrafine Particles
Two sessions within the Particulate Matter (PM) Working Group have highlighted a critical shift in air quality monitoring: the move away from traditional mass-based measurements toward tracking the number and surface area of the smallest particles. While PM2.5 is currently well-regulated, the scientific community is increasingly concerned about submicron and ultrafine particles (UFP), which pose…

A Synthesis of Expert Views on Submicron and Ultrafine Particles
For decades, the global standard for measuring indoor air quality (IAQ) has focused on PM2.5, particulate matter with an aerodynamic diameter of 2.5 micrometers or less. However, recent findings from the Particulate Matter Working Group suggest that this mass-based metric may be overlooking the most significant health risks. By synthesizing expert survey data and recent…
