"Home Gas Ranges Produce Toxic Gases, Lawrence Berkeley Lab Study Says"

"Air pollution isn't just an outdoor problem. Unhealthy fumes may be emitted inside your own home if you're cooking over an unvented gas stove."

"Almost two-thirds of California households using gas burners in the winter without venting range hoods are exposed to gases that can cause breathing problems, according to a new study by a team at Lawrence Berkeley Laboratory.

"Homes are exceeding air quality standards, exposing people to toxins who shouldn't be," said scientist Brett Singer, who contributed to the study."
