Short summary
Aerosol particles are a major public health concern, but particle properties contributing to their toxicity are not well known. Oxidising components such as peroxy acids might contribute significantly to particle toxicity. However, there is a lack of analytical methods for their characterisation. We synthesized three peroxy acids, developed an analysis method and showed that degradation affects peracid yield, likely leading to underestimation of their concentration in conventional analyses.
