Gas stoves emit cancer-linked chemical at dangerous levels, study finds

A new study led by Stanford University finds that using a gas stove or oven can raise indoor levels of benzene, a chemical linked to a higher risk of leukemia and other blood cell cancers, above those in secondhand tobacco smoke. Benzene can also migrate into other rooms far from the kitchen and linger for hours in home air. The study recommends using portable induction cooktops or electric kitchenware to reduce exposure to pollutants from gas stoves.
