I don't know if this is relevant but I worked in a plant that coated aluminum coils that were later produced for building materials, eavestrough, siding, etc. for 11 years.

Mind you I worked in the office, but the smell of the paint being baked onto the aluminum was over-powering some days. My eyes would actually water. I was diagnosed with Parkinson's some 14 years after I left.

I then worked for a school board where I was in constant touch with kids, new Canadians, etc. etc.
