NHDES Declares Air Quality Action Day
Unhealthy Air Pollution Levels Predicted for Today, Tomorrow and Wednesday

Concord, NH – The New Hampshire Department of Environmental Services (NHDES) is expecting air pollution concentrations to reach unhealthy levels for sensitive individuals in Rockingham County on Monday, August 6. Unhealthy air pollution levels are expected again in Rockingham and Hillsborough Counties and at elevations above 3,000 feet on Tuesday, August 7, and Wednesday, August 8. NHDES officials are calling for Air Quality Action Days and advise sensitive individuals in these areas to take precautions to protect their health by limiting prolonged outdoor exertion. Sensitive individuals include children and older adults, anyone with lung disease such as asthma, emphysema, and bronchitis, and people who are active outdoors. Even healthy individuals may experience mild health effects and should consider limiting strenuous or prolonged outdoor activities.

NHDES forecasts unhealthy concentrations of ground-level ozone (the main component of smog) for sensitive individuals in the above-mentioned regions. In addition, moderate levels of fine particle pollution are expected statewide during this event. The predicted unhealthy air quality comes from the persistence of high temperatures under sunny skies and winds transporting pollution into New Hampshire from surrounding areas in combination with local emissions. These air quality conditions may continue throughout the heatwave until cooler weather and cleaner air move into the state late Wednesday.

Symptoms of ozone exposure include coughing, wheezing, chest tightness or pain when inhaling deeply, and shortness of breath. The severity of the health effects increases as ozone concentrations increase.
