Carbon monoxide
Carbon Monoxide
CO3
Carbon monoxide comes out of a car. This colorless gas that is released from a car's exhaust is poisonous when inhaled in a highly concentrated form.
Vehicle exhaust is the gas emitted from engines after combustion.
It moves the poisonous gas away from the occupants of the car and also provides silencing of the waste gas by passing it through a silencer (Muffler). The exhaust system on modern gasoline engines also includes the catalytic converter to remove some of the poisonous, polluting, gases.
The lead is emitted by the car exhaust as a gas which can be absorbed in the bodies of people who breathe the gas. It accumulates in the body as the body has no mechanism to deal with it and affects the brain, reducing IQ.
