  The major car pollutants
are carbon monoxide,
hydrocarbons, nitrous
oxides, carbon dioxide,
and particulates. Most car
pollutants come from the
exhaust but brake pads,
tires, oil, grease, anti­
freeze, hydraulic fluids,
and cleaning agents also
contribute pollutants to
the environment. 

Motor vehicles emit toxic
and carcinogenic
compounds that are
known to cause cancer in
humans. Hydrocarbons
and nitrogen oxides
contribute to smog, which
damages lung tissues and
aggravates respiratory
disease.
