Carbon monoxide (CO)
Alias: Punky Carbone
Description: (Chemical Compound) Carbon monoxide is a colorless, odorless gas.
Crime: Breathing CO can cause serious health effects, or even death, because it replaces oxygen in the bloodstream.
Cause: CO is produced from the incomplete burning of fuel. Although emission controls are required, the large number of vehicles on the road make this the largest source of CO pollution. Indoors, CO may be produced at dangerous levels by unvented gas and kerosene heaters, wood stoves, and cigarette smoke.
