“…Samples were counted in a Packard Model 3314 Tri-Carb liquid scintillation counter, and the counts converted to decompositions from the efficiencies obtained after spiking the samples with standard toluene-14C. Gas, column, and thin-layer chromatography were used to isolate and determine the fungicide, and the modified colorimetric method of Kilgore and Cheng (1962), and a colorimetric method developed during this investigation based on dye coupling were used (Groves and Chough, 1966).…”

A series of trials in which cattle were either treated dermally or dosed orally with clenpirin [2-(3,4-dichlorophenylimino)-l-n-butyl pyrrolidine] was undertaken.Tissue fat from steers and butter fat from milking cattle were sampled and residue levels determined colorimetrically.Residues following a single application of clenpirin (9 Iitres/beast at 0.25 % w/v) reached an average maximum of 2.0 mg/kg in body fat and then declined to 0.2 mg/kg after 14 days. Multiple applications (9 litres/beast at 0.25% w/v) resulted in a progressive buildup of residues in body fat to about 10 mg/kg after 4 treatments. When steers were dosed orally with technical clenpirin at 700 mg/beast/day for 15 days the average fat level reached 0.7 mg/kg. In a series of trials with milking cattle a single dermal exposure (0.234.3 % w/v aqueous emulsion) yielded residues in butter fat ranging from 15.5-51.1 mg/kg at the first sampling 5 h after treatment. Six days later these had declined to about 0.8 mg/kg.
