Caledonia, Addison, Chittenden, Franklin, Essex, Grand Isle,

The air quality index, or AQI, is expected to approach or exceed the

When pollution levels are in the 151, the Vermont Department of
Health recommends that these 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, older adults, and those
with preexisting respiratory problems such as asthma or heart
disease and those working outside.

Those with symptoms should consider consulting their personal
physician.

People with asthma should follow their asthma action plans and keep
quick relief medicine handy.

If you have heart disease: symptoms such as palpitations, shortness
of breath, or unusual fatigue may indicate a serious problem. If you
have any of these, contact your healthcare provider.

An Air Quality Action Day means that particulate concentrations
within the region may approach or exceed unhealthy standards.
