Stanford study links gas stoves to cancer-causing benzene emissions.

Gas stoves emit benzene, a chemical linked to cancer, which can spread throughout a home and reach higher levels than secondhand tobacco smoke, according to a study by Stanford University. The research adds to growing evidence that emissions within the home are more harmful than previously believed. The American Public Health Association has labelled gas cooking stoves "a public health concern," and the American Medical Association warns that cooking with gas increases the risk of childhood asthma. Cheaper interim solutions include buying a portable induction cooktop or plug-in appliances, such as toaster ovens, that can reduce the amount of time necessary to use a gas stove.
