PM-2.5 is made up of small particles (soot) found in smoke. ADEQ recommends that people limit outdoor activity while the HPA is in effect, especially children and adults with respiratory problems.

Health Impacts

People most vulnerable to the impacts of air pollution include children, older adults, adults exercising outdoors and people with heart or lung disease and those suffering from asthma and bronchitis. Exposure can increase the number and severity of asthma attacks, cause or aggravate bronchitis or other lung disease and reduce the body’s ability to fight infection. Symptoms may include itchy eyes, nose, and throat, wheezing, coughing, shortness of breath, chest pain and upper respiratory issues. Long-term exposure is linked to premature death in people with heart or lung disease, nonfatal heart attacks, irregular heartbeat and decreased lung function.

Please help reduce PM-2.5 by doing one or more of the following:

  • Use gas or electric instead of burning wood
  • Limit the lighting of fireworks
  • Ride transit, carpool or telework
  • Eliminate all unnecessary driving and/or combine trips
  • If burning wood for heat or food preparation, use dry wood (burning wet wood releases more particulate matter)

Employers and Travel Reduction Program Transportation Coordinators should activate their HPA Plans immediately.
