...AIR QUALITY ALERT NOW IN EFFECT UNTIL MIDNIGHT EDT THURSDAY NIGHT...

The New York State Department of Environmental Conservation at
Albany has extended the Air Quality Health Advisory for Fine
Particulates, now in effect until midnight EDT Thursday night.

Air quality levels in outdoor air are predicted to be greater than
an air quality index value of 100 for Fine Particulates. 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
pre existing respiratory problems such as asthma or heart disease.
Those with symptoms should consider consulting their personal
physician.

Department of Environmental Conservation website at,

1345.
