Carbon Monoxide - CO
Carbon monoxide is a poisonous, invisible gas released from exhaust pipes when gasoline burns.
Over 80% of CO comes from cars and other vehicles.
How It Hurts
Carbon monoxide prevents our blood from delivering oxygen to our bodies. Small amounts cause headaches. Large amounts in closed spaces can suffocate and kill us.
