I hate to read it, but NPR reported on a Stanford study that found gas stoves increase levels of benzene in the home – a chemical that brings with it a noticeable increase in risk of cancer:
They found both natural gas and propane stoves “emitted detectable and repeatable levels of benzene that in some homes raised indoor benzene concentrations above well-established health benchmarks.”
…
With one burner on high or the oven at 350 degrees, the researchers found benzene levels in a house can be worse than average levels for second-hand tobacco smoke. And they found the toxin doesn’t just stay in the kitchen, it can migrate to other places, such as bedrooms.
…
Researchers also tested whether cooking food – pan-frying salmon or bacon – emits benzene but found all the pollution came from the gas and not the food. That’s important because the gas industry often deflects concern about pollution from its fuel, to breathing problems that can be triggered by cooking fumes.
There are no studies out there that say cooking with gas will make someone sick. This is all about increasing risks for certain illnesses.
…
Gas utilities have long researched how gas stoves pollute indoor air and even developed new styles of burners that use less gas and emit less nitrogen dioxide. But manufacturers don’t use them, saying they are more expensive, harder to clean and consumers aren’t demanding them.
