Ozone Advisory for Thursday

The New York State Department of Environmental Conservation issued an ozone health advisory Wednesday for the  Long Island region.

Suffolk County Health Commissioner Dr. James Tomarken advises that all residents, especially young children, seniors, those who exercise or are involved in strenuous outdoor work, and those with pre-existing respiratory or heart problems, limit strenuous outdoor activity.

Ozone levels are often elevated after noon through early evening on hot, sunny days.

Air Quality Forecasts are available on the New York State Department of Environmental Conservation website at http://www.dec.ny.gov/cfmx/extapps/aqi/aqi_forecast.cfm

Information about ozone and health is available on the New York State Department of Health website:


The Air Quality Index (AQI) is an index for  air quality each day. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. It 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 levels of ozone and/or fine particles are expected to exceed an AQI value of 100, an Air Quality Health Advisory is issued alerting sensitive groups to take the necessary precautions.

The Air Quality Forecast displays the predicted maximum Air Quality Index value for eight Air Quality Health Advisory regions in New York State. It also displays the observed maximum values for the previous day. DEC’s Air Quality Health Advisory regions consist of the following:

  • Region I Long Island – Nassau and Suffolk
