The monitoring of pesticide residues in agricultural products is essential to protect consumers, has been achieved for risk assessment and ensure fair trade practices. We developed a mutliresidue method for analysis of 37 pesticides with different physico-chemical properties in agricultural products and analyzed the amount of pesticide residues. The samples consisted of 26 different types of agricultural products selected at markets in 14 major cities; cereals(2 species), nuts(1 species) potatoes(1 species), beans(2 species), fruits(3 species), vegetables(16 species), and mushrooms(1 species). The results were as follows : on this study, residual pesticides were detected at 23 samples (2.2%) in leafy vegetables such as pepper leaves, radish leaves, cham-na-mul, shin-sun-cho, crown daisy, chwi-na-mul and citrus fruits such as kumquat. and one sample was detected over Maximum Residue Limits(MRLs) for pesticides in agricultural products. Eight kinds of pesticides were detected and Specially, Diazinon were detected over MRLs in radish leaves. According to the Korea Food Code, MRLs for pesticides was regulated by 0.1ppm in food. Also, Endosulfan, Ethoprophos and Phenthoate were detected frequently. From exposure assesment of pesticides in korea commercial agricultural products, daily uptake amount from agricultural products was only 0.003 ∼ 0.352% of ADI. It means that korea commercial agricultural products were safe on the whole for pesticides. In this study, QuECHERS method was applied for effective extraction and purification of pesticides in agricultural products, also MRM(Multiple Reaction Monitoring) mode in GC/MS/MS was used to secure precursor and transition ion from pesticides. From the analytical data, simultaneous analysis method of multi-residual pesticides by GC/MS/MS was very effective for monitoring of pesticides in commercial agricultural products.
