Procedure for the determination of 2,4-D and dicamba in inhalation, dermal, hand-wash, and urine samples from spray applicators.
Analytical procedures for the simultaneous determination of residues of 2,4-D and dicamba from polyurethane foam plug air samplers, ethylene glycol impregnated glass-fiber filter paper dermal samplers, 1% sodium bicarbonate hand wash solution, and urine are presented. Residues were derivatized with diazomethane and quantitated using electron capture gas chromatography. Recoveries were greater than 80% at the limit of detection in all substrates. The limits of detection for both herbicides were 0.1 microgram/foam plug and 0.5 micrograms/filter paper, and in the urine, 1.7 micrograms/100 mL and 5.0 micrograms/100 mL for dicamba and 2,4-D, respectively.
