Interesting, and possibly applicable to any activity where you turn

There is a whole spate of the hypersensitivity type of lung conditions
(extrinsic allergic alveolitis) which are occupation-related. They are not
always caused by bacteria: Farmer's lung is related to exposure to mouldy
hay, Bird-fancier lung is related to exposure to avian proteins, Lifeguard
lung to aerosolized endotoxin etc. etc.

Also, overexposure to less toxic irritants can sensitize and lead to an
outsized immune response, which can then become permanent.
