Studies in pesticide residues. 3. Ronnel residues in the perirenal and omental fat of cattle following dermal application

Abstract

Ronnel residues were determined in the perirenal and omental fat of cattle slaughtered at intervals of 1, 4, 7, 10, 13 or 16 days after one application of 2 gal of 0·1 % insecticide.
The maximum level (2 · 63 p.p.m.) was observed in the omental fat at 4 days and the minimum level (0 · 09 p.p.m.) in the perirenal fat at 16 days after treatment. After deposition
was complete, residues were consistently higher in the omental than in the perirenal fat.
