Have been reading more of the book _Life and Breath_ by Neil
Schachter. I was surprised to see the author claim that gas stoves
cause the formation of free radicals that can irritate the lungs. On
the one hand, like everybody else, I've been programmed by years of
claims that gas "burns clean" and "produces only CO2 as a byproduct."
On the other hand, air is mostly nitrogen and combustion should
produce some nitrogen oxides as well as CO2. Has anyone ever read a
credible study about the amount of production of noxious nitrogen
compounds due to the burning of natural gas? I'm considering using my
stove fan whenever I light a burner instead of just when the food is
smoking, but I'd like to see some real numbers.
On an unrelated topic, is the mechanism that produces inflammation in
the nose the same as that which produces inflammation in the lungs?
If so, it makes sense that the nose often gets stuffy before an asthma
problem, as the nose will get a higher dose first. Once the patient
starts to breathe through the mouth, then the air will be unfiltered
and the dose in the lungs will go up more rapidly. But sometimes
asthma attacks start without a stuffy nose, even in those who have
allergies. Does this mean that the cause of the attack isn't an
inhaled substance? Or do the nose and bronchial sensitivities likely
differ?

The "numbers" depend on your local source of natural gas. Maybe their
website has that specific information.
Good idea to vent any natural gas flame, due to CO (carbon monoxide),
which as you know is colorless and odorless, and (maybe a lesser known
fun fact) can be a major source of iron build-up in the body... :)

You won't get enough nitrous oxides to cause problems because a
natural gas flame is not hot enough to cause nitrogen to react with
oxygen.

Generally speaking, yes.

Yes and no. Generally the nose gets exposed fractions of a second
before the lungs. (has to do with the size particles that are
filtered by the various mechanisms in the airways. (And what
percentage actually gets filtered.
Your nose does not meet HEPA standards. :-)
