EPA has several programs to reduce air pollution and ozone concentrations. Technologies are available today that can cut this energy use significantly and, at the same time, improve our quality of life. Radiation can be defined as the process of emitting energy in the form of particles or waves. Here's a summary of how it works. Matter is composed of microscopic particles called atoms.
Radiation comes from atoms that are in the process of changing.
A few air pollutants, called criteria air pollutants , are common throughout the United States. These pollutants can injure health, harm the environment and cause property damage. To find out more in depth information about the criteria air pollutants, visit the Green Book site . Mobile sources produce air pollution from exhaust emissions, as well as evaporative emissions and refueling losses from gasoline engines. For example, diesel engines used in trucks, buses, locomotives, and ships tend to emit more NOx and PM than gasoline engines.
