You’ve got a significant misunderstanding on the level I’m talking about. Incomplete pyrolysis creates cancer causing compounds in the percentage level, gasoline and smoke has it in the parts per million. It’s multiple orders of magnitude more toxic. Gasoline fumes, wood smoke, and car exhaust are like breathing clean air compared to this shit.
The regulation for the average content of benzene in US gasoline is .62% and the WHO, as of march, classifies gasoline in its totality as a IARC group 1 Carcinogen.
Group 1 does not denote risk, just that it is definitely carcinogenic.
Again I’m not diminishing the fact some products of pyrolysis produced in significant amounts are very hazardous and carcinogenic, but I think you underestimate gasoline.
Industrial producer gas generally produces 5 percent aromatics by weight of feedstock with their light tar(the stuff diy gasifiers have to clean out) being roughly 70 percent benzene and toulene. There’s not data on diy gasifiers but expect it to be worse, with more varied polycyclics that likey much more toxic that aren’t particularly filtered out by bubbling it through water. These heavy polycyclics are generally eliminated in the gasoline cracking stage.
