Wildfire smoke from Canada prompts air quality health advisory
NEW YORK (WWTI) – New York DEC Commissioner Amanda Lefton and DOH Commissioner Dr. James McDonald are issuing an Air Quality Health Advisory for fine particulate matter on June 7, 2025, due to wildfire smoke from Canada.
Air quality alert issued for much of New York State
The pollutant of concern is: Fine Particulate Matter
The advisory will be in effect 10 a.m. through 11:59 p.m.
The Air Quality Health Advisory regions consist of: Adirondacks, which includes Clinton, Essex, Franklin, Hamilton, northern Herkimer, Lewis, St. Lawrence, and Warren counties; Eastern Lake Ontario, which includes northern Cayuga, Jefferson, Monroe, Oswego, and Wayne counties; Central New York, which includes Allegany, Broome, southern Cayuga, Chemung, Chenango, Cortland, Delaware, southern Herkimer, Livingston, Madison, Onondaga, Oneida, Ontario, Otsego, Tioga, Tompkins, Schuyler, Seneca, Steuben, and Yates, and Western New York, which includes Cattaraugus, Chautauqua, Erie, Genesee, Niagara, Orleans, and Wyoming counties.
DEC and DOH issue Air Quality Health Advisories when pollution levels, like ozone or PM2.5, are expected to exceed an AQI value of 100, indicating health risks.
Fine particulate matter (PM 2.5) consists of tiny particles or droplets in the air, measuring 2.5 microns or less. These particles can come from combustion sources like vehicle exhaust, power plants and fires, as well as chemical reactions in the atmosphere.
Exposure to PM 2.5 can lead to short-term health issues such as eye, nose and throat irritation, coughing, sneezing, and shortness of breath. It may also worsen conditions like asthma and heart disease, particularly affecting sensitive groups like those with heart or breathing problems, children, and the elderly.
To reduce exposure during elevated outdoor levels, staying indoors can help, although indoor sources like tobacco or cooking fumes can still keep levels high. Recommendations include minimizing sources of PM 2.5 and avoiding strenuous activities in polluted areas. More information is available on DEC's and DOH's websites.
