“…The amount of residual dimethoate was determined by the colorimetric method of George et al (1966). One unit of activity was defined as the amount of enzyme that catalyses the degradation of 1 lmol of dimethoate per minute under these conditions.…”

“…Although a number of analytical methods for dimethoate residues have appeared in the literature based on such techniques as colorimetry (Chillwell and Beecham, 1960; Giang and Schechter, 1963;Van Middelem and Waites, 1964;George et al, 1966), paper chromatography (Enos and Frear, 1962), total phosphorus determination (Steller and Curry, 1964), and gas chromatography (Storherr and Watts, 1969; Steller and Pasarela, 1972; Woodham et al, 1974a,b), these methods were designed either for dimethoate alone, or for dimethoate and its oxygen analogue (dimethoxon, omethoate). In some cases, the methods require that dimethoate and dimethoxon be analyzed separately, while several of the methods quantitate without distinguishing between the two.…”
