The possibility on the use of multi-residue analysis for 81 different pesticides was
confirmed after the establishment of qualitative and quantitative analysis conditions that
increased pesticide selectivity and detection sensitivity through the use of LC-MS/MS.
Detection limits for all 81 pesticides satisfied the levels defined for domestic foods. The
linearities of the calibration curves ranged between 0.9800 and 0.9999. Recovery for this
analysis method was tested by applying it to Ssam cabbage and pepper with final
concentrations of 0.05 to 0.1 mg/kg. This analysis was performed after the recovery
experiments had been replicated three times. The recovery results were good even
though there were small differences by vegetables and concentration levels. The
pesticide levels for 239 samples in 43 vegetables were monitored using this analytical
method. No pesticide exceeded the maximum residue limits(MRLs). However, 17
pesticides with levels that ranged between 0.02 and 5.86
