Rats were exposed to metered concentrations of EDA vapor for 8h. Six
male rats per dose group were exposed to 2000 and 4000 ppm EDA vapour
for 8h. Mortality of rats was observed for a 14 day period. No deaths
were observed in the 2000 ppm dose group, and 100% mortality was
observed in the 4000 ppm dose group. Taking the geometric mean as the
LC50 value, and calculating back to 4h exposure gives an LC50 of 14.7
