Atmospheric characterization. (a) Visual representation of each exposure group demonstrating the relevant size and complexity of ultrafine particulate matter (UFP), ultrafine particulate matter combined with vehicular gases (UFP + G), fine particulate matter (FP), and fine particulate matter combined with gases (FP + G). The particulate matter target concentration (300 μg/m3) was reached for each exposure group in both the (b) 1-day (acute) and (c) 30-day (chronic) studies. The distribution of the (d) ultrafine particle (UFP) group is in the nanometer range, similar to the distribution of the (f) ultrafine particles recombined with vehicular gases (UFP + G) group. Characterization of the (e) fine particle (FP) and (g) fine particles recombined with vehicular gases (FP + G) demonstrate that these exposures do not contain detectable PM in the nanometer ultrafine range suggesting larger particulate matter size
