Chapter 4 Carbon dioxide (CO2) is not a pollutant that would harm our health but it is a proven greenhouse gas. High concentrations of SO2 can result in temporary breathing impairment for asthmatic children and adults who are active outdoors. Short-term exposures of asthmatic individuals to elevated SO2 levels during moderate activity may result in breathing difficulties that can be accompanied by symptoms such as wheezing, chest tightness, or shortness of breath. Carbon in the fuel combines with the oxygen in the air used for burning and forms carbon dioxide. If there is not enough oxygen for complete oxidation, carbon monoxide (CO) may form. The United States continues to be the largest single emitter of fossil fuel- related CO2 emissions reaching an all-time high of 1,529 million metric tons of carbon in 2000. Methane is a greenhouse gas formed due to decomposition of organic wastes, formed in land fills, and during raising livestock. It is also a major component of natural gas, which is formed as result of decomposition of plants millions of years ago. CO2 is a greenhouse gas which has an ability to absorb infrared radiation that is escaping from the surface of the earth causing the atmosphere to warm up. SO2 is not. The pollutants that are emitted directly from a combustion process are called "primary pollutants." Ozone is a secondary pollutant. The United States continues to be the largest single emitter of fossil fuel- related CO2 emissions reaching an all-time high of 1,529 million metric tons of carbon in 2000. Nitrogen oxides can form from both nitrogen in the fuel and nitrogen in the air used for combustion. The highest levels of CO in the outside air typically occur during the colder months of the year when inversion conditions are more frequent. An inversion is an atmospheric condition that occurs when the air pollutants are trapped near the ground beneath a layer of warm air.

Most of the emissions from combustion devices (approximately 90%) are in the form of NO. SO2 dissolves in water vapor to form acid, and interacts with other gases
