2 - Frying chicken results in some particulate matter (PM10) but that doesn't seem to be a global warming concern or an asthma concern, and it settles out of the air quickly. But if you have an "industrial exhaust" as you say, all the oil gets sucked out anyways so it doesn't even matter
3 - Poorly designed ventilation is precisely where switching to electric has the biggest benefit, not the smallest, since cooking is the #1 source of indoor particulate matter and CO2
4 - This is why lots of people clean with gentler cleaning products. But they don't seem to contribute to global warming or asthma in the same way from what we know, and most people aren't using crazy harsh cleaning chemicals multiple times daily the way they do the stove, so it seems like a much smaller issue
1. Gas ovens 2. What you’re cooking. Frying chicken on an induction stovetop is probably going to do more damage to the air quality than gas stoves with industrial exhausts (I have the latter) 3. House layout. This one possibly bothers me the most. There are so many houses with poorly designed ventilation. Replacing stovetops is not going to significantly improve air quality. My open kitchen with really good exhausts are going to have much better air quality with a gas stove than most houses with an electric one. 4. Other household items. Hundreds of other products like cleaning agents still will continue to pollute indoor air with carcinogens but no one will ban them.
