A new study by CPWR researchers assessed the potential to exceed occupational exposure limits while spraying paint with and without a silver nanoparticle biocidal additive. The results suggest a low probability of exceeding a proposed silver nanoparticle exposure limit of 0.9 µg/m3 as an airborne 8-hr time-weighted average respirable mass concentration.
