충남대학교 화학과,
A rapid and simple method for the sensitive and selective determination of carbamate insecticides, fungicides including 35 mixture pesticides in cabbage vegetable matrices has been developed. The extracts are analyzed by liquid chromatography electrospray ionization tandem mass spectrometry. A method was validated for the multi-residue analysis of 35 pesticides in Korea cabbage at ≤10 ng/g level. Cleaned by dispersive solid phase extraction and the results were obtained by liquid chromatography tandem mass spectrometry. Average recoveries of the pesticides were between 70 and 120 % at both spiking levels 10 and 20 ng/g in cabbage. Relative standard deviations (RSD) were less than 15 % for all of the recovery tests. The calculated limits of quantitation (LOQ) (3-50 ng/kg) were much lower than the maximum residues limits (MRL) established by KFDA (0.1-5 mg/kg). The proposed method is fast and easy to perform and could be utilized for monitoring of pesticieds residues.
