smog warning

But people seem unconcerned, i only met one person who was interested in it and the smog warnings in early summer.

They began issuing smog warnings on Wednesday.

There is a winter smog warning in southern Quebec, Ontario as a result of pollution and unusually warm weather.

Chiba, an eastern suburb, has received two smog warnings, more dangerous than an alert, the first such warnings in 17 years.

The great irony of the heat wave came in Boston, where, even as the Department of Environmental Protection was issuing smog warnings, representatives of Ford, Chrysler and General Motors were meeting with Massachusetts Gov. William F. Weld to ask him to drop his support for pollution-free electric cars.
