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-10 by doing one or more of the following:

  • Avoid dirt roads.
  • Avoid the use of leaf blowers.
  • Ride transit, carpool or telework.
  • Eliminate all unnecessary driving and/or combine trips.
  • Employers and Travel Reduction Program Transportation Coordinators should activate their HPA Plans immediately.
