So there's stuff about this that confuses me. Are US gas stoves always burning gas for a pilot flame? Is that the issue? Are there no regulations about kitchen ventiation for gas installations? Is it less usual to have an active smoke extractor over your stove? Are all the kitchen walls in the US super gross as a result?
Gas stoves are on the way out as general climate change (and energy dependency) pushes away from gas anyway, and I haven't seen a functional gas oven in decades, but still, some of the language in the discussion and in this study seem to assume something different than what I expect when somebody says "gas stove".
