Acethion (0,0-diethyl S-carboethoxymethylphosphorodithioate) 
Degradation of acethion was rapid and 77-88% of the injected 
dose appeared as chloroform extractables within 0.5 hr. after 
treatment (Perry, 1960a). Chromatographic separation and analysis 
showed the principal metabolite to be acethion acid. Some mono- 
and diethyl phosphorodithioic acids were also found (O'Brien et 
al., 1958; Krueger et al., 1960).
