Abstract
The details of the methodology of the study are described, and the results are discussed. The measurement of acetaldehyde in precipitated blood seemed to be complicated by the production of acetaldehyde from a nonethanol source. It was also found that the stotz colorimetric procedure does not liberate significant amounts of acetaldehyde if the precipitated blood is promptly distilled because the precipitate is separated before raising the temperature in distillation. The findings indicate that further refinement in methods will be required before accurate estimation of the amounts of acetaldehyde produced in blood by ethanol metabolism is possible.
