HPLC Determination of
Flumethrin, Deltamethrin, Cypermethrin, and Cyhalothrin Residues
in the Milk and Blood or Lactating Dairy Cows
D. Zuccari
Bissacot and I. Vassilieff
A procedure to determine residue concentrations of synthetic pyrethroid insecticides (flumethrin, deltamethrin, cypermethrin and cyhalothrin) in the milk and blood of lactating dairy cows was developed. Extraction was performed with acetonitrile, n-hexane partitioning, and silica gel column cleanup with n-hexane and diethyl ether. Analysis was carried out by high-performance liquid chromatography and ultraviolet detection. Recovery of the four pyrethroids averaged 78 to 91% with a minimum detectable concentration of 0.001 mg/kg. The method was reproducible and sensitive.
