aStatistics were computed by exponentiating 1-min averaged logged concentrations, determining the increase amount within subject samples (subject, day and microenvironment), then computing composite statistics across the 125 samples. PM concentrations (micrograms per cubic meter) have been corrected by gravimetric filter mass collected concurrently with each daily pDR sample
