Unhealthy Air 

Federal environmental officials are expecting the air quality to be unhealthy this weekend in

Connecticut, Massachusetts, Rhode Island and parts of Maine,

Vermont and New Hampshire.

Robert Varney, the Environmental Protection Agency’s regional

administrator, says people should limit strenuous outdoor activity.

Exposure to smog can cause serious breathing problems, aggravate

asthma and other pre-existing lung diseases. Exposure also can make

people more susceptible to respiratory infection.

The EPA expects more air quality alerts this summer because it

has lowered the level of ground-level ozone – or smog – that

triggers a public warning.
