State Declares Air Quality Action Day
Unhealthy Air Pollution Levels Predicted for Today
Concord, NH -- The New Hampshire Department of Environmental Services (DES) is expecting air pollution concentrations to reach unhealthy levels for sensitive individuals in Cheshire, Hillsborough, and Rockingham counties, particularly in populated valley areas, on Monday, February 2. Concentrations are expected to be highest overnight. DES officials are calling for an Air Quality Action Day and advise sensitive individuals in these areas to take precautions to protect their health by reducing prolonged or heavy exertion. Sensitive individuals include children, older adults, and anyone with heart or lung disease such as asthma, emphysema, and bronchitis. Even healthy individuals may experience mild health effects and should consider limiting strenuous or prolonged activities.
DES forecasts concentrations of fine particle pollution to be unhealthy for sensitive individuals in the above-mentioned regions. The expected unhealthy particle pollution levels are a result of cold, stagnant air and temperature inversions which limit air movement. Pollutants being emitted from heating devices, especially residential wood burning stoves and furnaces, are trapped and become concentrated near the ground. Communities located in valleys or other low-lying areas are more strongly affected. Conditions are expected to improve early on Tuesday as wind speeds increase, resulting in better mixing and cleaner air.
Symptoms of particle pollution exposure for people with heart disease may include chest pain, palpitations, shortness of breath, and fatigue. People with existing lung diseases may not be able to breathe as deeply or vigorously as normal and may experience symptoms such as coughing and shortness of breath. The severity of the health effects increases as fine particle concentrations increase. In addition to harmful health effects, fine particle pollution may create hazy conditions that reduce visibility.
