The New York State Department of Environmental Conservation has

Ozone . The Air Quality Index...or AQI...was created as an easy way

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.
