Air Quality

Outdoor Air Quality with little boy playing by pollutionWhen was the last time you thought about breathing? There are things we take for granted that we do every day, and breathing is one of them. In fact, the average adult takes about 23,000 breathes each day and the average child takes about 43,000. Breathing is essential to life and everyone should have the right to breathe clean air. 

Air pollution occurs when the air contains gases, dust, fumes, or odors that make it harmful to breathe. Substances that cause air pollution are called pollutants and include particulate matter (soot), ozone, lead, and carbon dioxide. Since 1750, humans have released more pollutants into the air than ever before due to industrialization, urbanization and mass agriculture. For example, 375 billion tons of carbon dioxide have been released into the atmosphere from human activities since the start of the industrial era (World Meteorological Organization). Pollutants come from sources like electric utilities, motor vehicles, wildfires and even sources within our own homes. Air pollutants lower our air quality and can cause serious health problems such as:

  • Asthma
  • Heart attacks and strokes
  • Cardiovascular disease
  • Chronic Obstructive Pulmonary Disease (COPD)
  • Reduced fertility
  • Lung cancer

Air pollution affects all people. However, it can have a more serious impact on sensitive members of our community such as the young, elderly, people with low socioeconomic status and those with certain pre-existing health conditions. These facts demonstrate the widespread health effects of poor air quality:

Environmental Health (EH) professionals play a large role in the reduction and prevention of air pollution through monitoring and education programs. The Clean Air Act is a law that protects our air quality by regulating emissions of hazardous pollutants from stationary and mobile sources and authorizes the EPA to establish National Ambient Air Quality Standards (NAAQS) to improve public health and welfare. The Air Quality Index (AQI) is an index for reporting daily air quality. It tells you how clean or polluted your air is and what associated health effects might be a concern for you.

Environmental Health Saves Lives, Saves Money, and Protects Our Future

Environmental Health professionals ensure the air we breathe is safe by testing and monitoring air in the places we live and work.
