*Mean PM2.5 concentration is using gravimetric measurements.
†Mean hourly CO concentrations at dashboard (dash), middle (mid) and backseat (back) locations inside the vehicle.
‡Air Exchange Rates (ACH) calculated using CO concentration and equation 1 hour mean nicotine concentrations (μg/m3).
In, inside vehicle at the back seat; Out, outside of vehicle.
