This study was monitored for 14 pesticide residues in agricultural products for the army, such as fruit vegetables(pepper, cucumber, pumpkin, melon and water melon), leafy vegetables(Korean cabbage, spinach, lettuce, crown daisy, cabbage, green onion), mushrooms(agaric, p'yogo), and bean sprouts produced in Kyunggi-do and Inchon-City. From January to December 2005, ten carbamate pesticides in 356 samples were analyzed by HPLC. One kind of pesticide was detected in 8 samples of detection rate (2.53%), and two pesticides were in one sample of detection rate(0.27%). Aldicarb, bendiocarb, fenobucarb, methiocarb, isoprocarb, and propoxur were not found in all samples. Detection rates of pesticides were 0.84% for methomyl, 0.56% for carbofuran, 0.56% for ethiofencarb, and 0.28% for carbayl. Dectection ranges of pesticides were from 0.01 to 2.9 mg/kg for ethiofencarb, from 0.1 to 0.23 mg/kg for methomyl, from 0.20 to 0.24 mg/kg for carbofuran, and 0.01 mg/kg for carbaryl, respectively. Consequently, detection levels of all pesticides in samples were less than the maximum residue limits(MRLs) in Korea representing that all agricultural products for the army were safe.

The purpose of this study is to monitor the pesticide residues in frozen fruits and vegetables distributed and sold in online and offline markets in Korea. For the study, 107 samples of 34 types of frozen fruits and vegetables were examined, and a total of 341 pesticide residues were analyzed by using multiclass pesticide multi-residue methods of the Korean Food Code. As a result, pesticide residues were detected from 16 of 64 frozen fruits samples and 15 of 43 frozen vegetables samples. Conclusively, residues were detected from 31 samples in total, showing a detection rate of 29.0%. Specifically, pyridaben exceeded the Maximum Residue Limits (MRLs) based on the Positive list system (PLS) in one of the frozen radish leaves, and the violation rate was 0.9%. Detection on frozen fruits and vegetables was made 23 times for 11 types and 36 times for 21 types. In total, 28 types of pesticide residues were detected 59 times. Fungicides were detected the most in frozen fruits, while insecticides were detected the most in frozen vegetables. The most detected pesticides were the insecticide, acaricide chlorfenapyr (5) and the fungicide boscalid (5). Chlorfenapyr was detected only in frozen vegetables, and boscalid was detected in frozen fruits except one.
