Yeah I don't know for sure.  UV is certainly capable of damaging a lot

CO2 is relatively inert, and can be used to expand foam rubber. IIRC ozone (mutant oxygen) is the gas that deteriorates tires.

Wood is just a rearrangement of atoms from air. Several other rearrangements of air are deadly toxins, rocket fuels or both.
