Vermont DEC Declares Smoke Advisory: Elevated Particle Air Pollution Advisory Issued for Wednesday Through Friday

Montpelier, Vt. – The Vermont Department of Environmental Conservation (DEC) is forecasting moderate concentrations of fine particle air pollution from smoke to affect the state Wednesday through Friday. The particle pollution is the result of wildfire smoke from Nova Scotia, Canada. Wildfire smoke can cause a hazy or milky appearance in the sky and may be noticeable by smell at times.

Although air quality is expected to remain acceptable and not exceed the federal health standard, DEC advises individuals who are unusually sensitive to air pollution (including children, older adults, and anyone with heart or lung disease such as asthma, emphysema, and bronchitis), or anyone especially sensitive to smoke, to take precautions to protect their health by limiting prolonged outdoor exposure and exertion and to monitor their symptoms.

Wind patterns will likely transport plumes of smoke from these fires across much of the northeast, including Vermont. Air quality is expected to improve Friday when forecasted winds will push the smoke plumes out of the region.

Fine particle exposure symptoms increase as fine particle concentrations increase. Symptoms of particle pollution exposure may include chest pain, palpitations, coughing, shortness of breath, and difficulty breathing. In addition, people with asthma and other existing lung diseases may not be able to breathe as deeply or vigorously as normal.
