Can the smell of electronics be dangerous? New/old/burnt out?

So this may seem very random, but I am an artist who is trying to capture the scent of electronics, new motherboards, old burnt out hardware, nostalgic e-materials -- think hot dust, ozone, phenolic resin, burnt plastic and metal, etc. To do this is fairly simple, I'm just absorbing the aroma molecules of discarded electronics using fat, but I want to make sure I'm not actually doing anything that would be harmful to inhale. I am a bit out of my depth with my knowledge of the dangers of these scent materials - does anyone know if inhaling these electronic smells is generally bad? Is there anything I should definitely avoid capturing, older electronics or specific materials for example? At the moment I''m concerned about VOC (volatile organic compounds), and I've heard to avoid older transistors. Thanks in advance!
