Thanks for the url. I'll see if they have anything that might be useful.
Another part of the problem is the mold may be growing in hidden places
outside the heating ducts, and leaks into the heating system through the
joints. You'd have to tear the place apart to find it. Anyway, it's not
an abnormal amount, and no one else in the apartment is affected.
As far as killing spores, I haven't found anything effective. Mold and
fungus are among the oldest living things on the planet. They have had a
long time to refine the protection for the spores, and they are almost
indestructable. A little bit of UV for a brief time won't inactivate
them. The spores may have to travel for many years in bright sunlight
before finding a place to germinate. Even if UV did kill them, the spores
still contain very toxic material, so dead ones make you just as sick.
It's interesting that the toxicity is part of the biological warfare
among plants. The effects are aimed at competing molds and bacteria, not
at us. The effect it has on humans is merely collateral damage.
We actually need molds and fungus to break down unwanted material.
Without their assistance, we would be smothered in debris left over from
millions of years of biological activity.

Hah! This stuff comes down from the Arctic. Without us to warm it up for
you, you would really find it unbearable.
