Abstract
When a steer was fed 5 ppm of 2, 4-D, it was eliminated almost quantitatively as a salt in the urine. When a steer was fed 5 ppm of the herbicide 4-(2, 4-DB), about 10% was eliminated as a salt of 2, 4-D in the urine. A trace of 4-(2, 4-DB) was also present in the urine as a salt. Beta oxidation in the animals'' liver probably caused this conversion. Electron affinity gas chromatography was used to show these results.This publication has 4 references indexed in Scilit:
