The New York State Department of Environmental Conservation's Air Quality Health Advisory for the following counties: New York, Bronx, Kings, Queens, Richmond, Westchester and Rockland, remains in effect until 11 PM EDT this evening. Another air quality health advisory has been issued for these same areas on Monday between 11 AM and 11 PM EDT. Air quality levels in outdoor air are predicted to be greater than an Air Quality Index value of 100 for the pollutant of Ground Level Ozone. The Air Quality Index, or AQI, was created as an easy way to correlate levels of different pollutants to one scale. The higher the AQI value, the greater the health concern. When pollution levels are elevated, the New York State Department of Health recommends that individuals consider limiting strenuous outdoor physical activity to reduce the risk of adverse health effects. People who may be especially sensitive to the effects of elevated levels of pollutants include the very young, and those with preexisting respiratory problems such as asthma or heart disease. Those with symptoms should consider consulting their personal physician. For additional information, please visit the New York State Department of Environmental Conservation website at, https://on.ny.gov/nyaqi, or call the Air Quality Hotline at 1 800 5 3 5, 1 3 4 5.
