Table 2 Characteristics of P + SOA exposure

From: Inhaled ambient-level traffic-derived particulates decrease cardiac vagal influence and baroreflexes and increase arrhythmia in a rat model of metabolic syndrome

Pollutant ND MetS
PM2.5 Mass (μg/m3) 56.3 ± 1.2 20.4 ± 0.9
PM2.5 Count (thousand/cm3) 9.0 ± 0.2 6.6 ± 0.2
PM2.5 MMD (nm) 297.0 ± 6 262.7 ± 2
PM2.5 CMD (nm) 135.0 ± 2 95.2 ± 2
NO (ppb) 1.0 ± 0 3.2 ± 1.2
NOx (ppb) 2.6 ± 0.5 11.3 ± 1
O3 (ppb) - - 22.7 ± 2.1
CO (ppm) - - 1.0 ±0
  1. Means ± SE over entire 12-day exposure period. PM2.5 MMD and CMD denote mass and count median diameters ± geometric standard deviation. P + SOA exposure of ND rats applied the same parallel gas denuders as for MetS, but CO and O3 were not measured. FA was not monitored
