Air Quality Health Advisory Issued for New York City Metro Region

New York State Department of Environmental Conservation (DEC) Interim Commissioner Sean Mahar and State Department of Health (DOH) Commissioner Dr. James McDonald issued an Air Quality Health Advisory for today, Saturday, Nov. 9, 2024, for fine particulate matter for the New York City Metro region.

Air quality is forecasted to reach 'Unhealthy for Sensitive Groups' AQI on Saturday in the New York City Metro Region. At this level, members of sensitive groups may experience health effects. The general public is not likely to be affected. Find chart at DEC's website.

The pollutant of concern is: Fine Particulate Matter

The advisory will be in effect 11 a.m. through midnight.

The Saturday, Nov. 9, Air Quality Health Advisory regions consist of: New York City Metro, which includes New York City, Rockland, and Westchester counties.

DEC and DOH issue Air Quality Health Advisories when DEC meteorologists predict levels of pollution, either ozone or fine particulate matter (PM2.5), are expected to exceed an Air Quality Index (AQI) value of 100. The AQI was created as an easy way to correlate levels of different pollutants to one scale, with a higher AQI value indicating a greater health concern.

Fine Particulate Matter
Fine particulate matter consists of tiny solid particles or liquid droplets in the air that are 2.5 microns or less in diameter. PM 2.5 can be made of many different types of particles and often come from processes that involve combustion (e.g. vehicle exhaust, power plants, and fires) and from chemical reactions in the atmosphere.

Exposure can cause short-term health effects, such as irritation to the eyes, nose, and throat, coughing, sneezing, runny nose, and shortness of breath. Exposure to elevated levels of fine particulate matter can also worsen medical conditions such as asthma and heart disease. People with heart or breathing problems, and children and the elderly may be particularly sensitive to PM 2.5.

When outdoor levels are elevated, going indoors may reduce exposure. If there are significant indoor sources of PM 2.5 (tobacco, candle or incense smoke, or fumes from cooking) levels inside may not be lower than outside. Some ways to reduce exposure are to minimize outdoor and indoor sources and avoid strenuous activities in areas where fine particle concentrations are high. Additional information on ozone and PM 2.5 is available on DEC's website and on DOH's website.

In New York, dry conditions across the state are resulting in a "high" fire danger rating in several regions including New York City, Long Island, and the Hudson Valley. A high fire danger means all fine, dead fuels ignite readily and fires start easily from most causes, including unattended brush and campfires. Fires may become serious and controlling them difficult unless attacked successfully while still small. The remainder of New York State is at a moderate level of fire danger. An updated fire danger map is available on the DEC website. While the statewide burn ban is no longer in effect, brush burning should only be done when absolutely necessary. Burning garbage or leaves is prohibited year-round in New York State.

Open burning is prohibited in New York, with these exceptions:

• Campfires or any other outdoor fires less than 3 feet in height and 4 feet in length, width or diameter are allowed.
• Small cooking fires are allowed.
• Ceremonial or celebratory bonfires are allowed. Disposal of flags or religious items in a small-sized fire is allowed, if it is not otherwise prohibited by law or regulation.
• Only charcoal or dry, clean, untreated or unpainted wood can be burned.
• Fires cannot be left unattended and must be fully extinguished.
