Pesticide Residue Analysis in Foods by NMR. 3. Comparison of 19F NMR and GC-ECD for Analyzing Trifluralin Residues in Field-Grown Carrots

Carrots were grown in trifluralin-treated soil and sampled over a 6-week period beginning 6 weeks after seeding. The residue of pesticide and principal metabolite in the carrot was measured by both 19F NMR and GC-ECD. The trifluralin concentration was observed to decline from 0.3 to 0.03 mg/kg. Alth...
