EPA calls these pollutants “criteria” air pollutants because it sets NAAQS for them based on the criteria, which are characterizations of the latest scientific information regarding their effects on health or welfare. Nitrogen Dioxide (NO 2).

Sulfur Dioxide (SO 2). Carbon Monoxide (CO): Carbon Monoxide is a highly toxic and dangerous pollutant,. Decreases lung function and causes respiratory symptoms, such as coughing and shortness of breath, and also makes asthma and other lung diseases get worse. Long term effects of particle matter air pollution includes chronic respiratory disease , heart disease and lung cancer.

Ozone (O3): Ozone is not inherently bad. It can also cause damage to the brain, liver , kidneys and nervous system. Being exposed continually to air pollution affects the lungs of children at a faster rate and also is very damaging to the elderly.

As such, the traditional practice of wood and charcoal burning is usually a chief contributor to indoor air pollution in developing nations. This can be due to leaching from waste disposal, increased human activity or industrial accidents.

Today, pollution levels in many areas of the United States exceed national air quality standards for at least one of the six common pollutants : Although levels of particle pollution and ground-level ozone pollution are substantially lower. For unhealthy peak levels of sulfur dioxide and nitrogen. EPA is required to control 1hazardous air pollutants. ADVERTISEMENTS: Read this article to learn about the types, sources, effects and control of air pollution ! Air pollution is a change in the physical, chemical and biological characteristic of air that causes adverse effects on humans and other organisms.
