I don't know the numbers, but the premise here is not (a) that gas is bad or that (b) cooking releases particulate, but rather that gas stoves are actually constantly leaking very small amounts of particulate that in aggregate can cause harm along the same lines of other sources of PM2.5 pollution.

Gas stoves might be constantly leaking, but they only produce particulates when they are alight. Assuming you don't have an ancient appliance with a pilot light.
