TL;DR: Evidence was found that the polycyclic hydrocarbons were not produced by the action of the heat on the singed material but rather that they were taken up as intermediary products of incomplete combustion of the fuel.
Abstract: The contents of polycyclic hydrocarbons, including the carcinogen 3:4 benzpyrene, in singed food depends on the fuel used. Evidence was found that the polycyclic hydrocarbons were not produced by the action of the heat on the singed material but rather that they were taken up as intermediary products of incomplete combustion of the fuel. When combustion of fuel is nearly complete, as in the flame of propane or acetylene‐oxygen, only negligible amounts of polycyclic hydrocarbons are found in the singed material whereas they are taken up in considerable quantities when fuel of lower rate of combustion as coal or diesel oil is used. Sheep heads singed over slow‐burning fuels such as peat or coal have been a common dietary source of the carcinogen 3:4 benzpyrene and other polycyclic hydrocarbons in Iceland and the same applies to singed birds in some locations.

TL;DR: It was concluded that carbon tetrachloride must be a considerably more toxic substance than trichloroethylene during the 20-years period 1945–1964.
Abstract: A report is given of all known cases of carbon tetrachloride poisoning treated at hospitals and/or coming to autopsy at the Department of Pathology, University of Iceland, Reykjavik, during the 20-years period 1945–1964.
