Well the first thing is that it is very unlikely that PVC or polyurethane fumes can cause damage to the neurological system whether that is of an adult (like yourself) or a child. That being said , this is true for LONG TERM neurological damage, in the short term it can cause headaches in individuals who are predisposed to develop migraines or have previous neurological issues as it can cause transient swelling of brain cells leading to a headache. I would like to emphasize that it is a TRANSIENT effect NOT a long term effect, it occurs as long as you are in proximity of the fumes once you leave the proximity, the effects subside with NO long term damage.
It can however cause lung issues more commonly in young children as they are more susceptible to developing attacks of astham especially if they already have allergies.
What exactly is the fume being emitted by PVC or polyurethane?
It is actually composed of a chemical byproduct of polyurethane itself, usually chairs and other substances which use this substance dont emit the fumes however sometimes due to a defect in the manufacturing process it can.
Oh, also - what if the fumes accidentally get heated? If I cook food on a flame in the kitchen, or use the dryer, either way, there would be fumes getting sucked into an extremely high-temperature heat, would that convert it into an even more toxic carcinogen or phosgene-like toxin?
No, heating the fumes would not lead to the development of a more toxic carcinogen but if the chair itself is burned then that can certainly cause production of more toxic fumes.
