Air quality in western Pennsylvania improved in 2016, according to three regional monitors tracked by the Allegheny County Health Department.

“It was a good year in ozone,” said Jayme Graham, the department's air quality manager.

Gov. Tom Corbett signed a bill last week that eliminates requirements for what’s called “summer gas.”

Seven counties in Western Pennsylvania require that a different kind of gasoline be sold during the summer. It evaporates less readily, releasing less of the pollutants that contribute to smog.

Homeowners are beginning to pull mowers and trimmers out of garages and sheds to work on their lawns, and although the gasoline-fueled tools might make the yard look presentable, they could be bad news for human health and the environment.

Lawn mowers, trimmers, chainsaws and leaf blowers, which are powered by gasoline, can create volatile organic compounds according to a public/private air quality group.
