Hemoglobin, which is in the blood, combines with carbon monoxide and carries less oxygen to body tissues causing health and heart effects. Some health problems come from the exhaust fumes leaking into the interior of the automobile. Several hundred Americans die from CO poisoning each year. Sodium oxide levels below .25 ppm have been associated with increased morbidity in New York as measured by hospital admissions. The fourth type is hydrocarbons which are chemical compounds containing only carbon and hydrogen.
Hydrocarbons also arise from gasoline-powered vehicles and from industrial processes.
The last type is nitrogen oxides that come from high-temperature combustion, such as that occurring in motor vehicle engines, electric power plants and other fuel usage. Nitrogen oxide contributes to acidity in precipitation and production of photochemical smog. Nitrogen oxide is also dangerous it causes serious illness and deaths even if the exposure to NO2 is short. As one can surely see these types of air pollutants are harmful to our atmosphere, environment and personal health. Factory owners can help prevent all of these effects.
