[Further measurements of the 14C-content of fermentation alcohol in dependence of growth times and location of the fermentation material (author's transl)].
The carbon-14 content of ethanol obtained from material (mostly potatoes) grown in the years 1964--1973 is compared with that of material of the vegetation periods 1956--1966 determined by other laboratories. Six ethanol samples from material grown 1973 in different parts of Europe show no significant differences. The average value is 19.3 dpm/g carbon. Furthermore no significant difference was found in ethanol from potatoes cultivated 50--800 m east and west of a freeway with very heavy traffic. The same is true also for ethanol from potatoes grown near a large industrial area and others grown far from such an area.
