Toxic Air Pollution In Urban Parking Garages: SUVs Pollute Slightly More
Taken from sciencedaily.com
ScienceDaily (Aug. 27, 2007) — The pollution produced by light trucks, SUVs and minivans is only half a percent higher than that produced by conventional cars, based on a recent study.
But researchers say that this tiny difference becomes enormous when considering the number of light trucks moving along the nation’s highways.
“That small difference [...]
