A newly designed apparatus for testing blood levels of fuel vapor

An apparatus for exposure of laboratory animals to fuel vapor was designed, manufactured and set up for routine experiments. Gasoline was vaporized by warming and was introduced into a series of chambers in which the concentration was regulated and stabilized, using air pumps. Concentration of the vapor in a chamber was controlled and experiments on rats showed a positive correlation between blood levels and vapor concentration at the time of exposure. A case of suicide by gasoline poisoning was briefly described.
