BACKGROUND : This study was conducted to monitor the residue of pesticides and to assess their risk in domestic agricultural products, such as fruit vegetables, tomatoes, oriental melons and root vegetables, garlic, potatoes and onions. METHODS AND RESULTS: 250 samples containing both general and environment-friendly certified agricultural products were collected from traditional markets and supermarkets in 6 cities. 132 pesticides except for herbicides were analysed using the multi-residue methods by GC/ECD, GC/NPD and HPLC/UVD. 17 kinds of pesticides were detected from 42 samples, which were 32 general, 1 organic, 4 pesticide-free and 5 low pesticide agricultural products. Among those, myclobutanil detected in 1 potato and procymidone detected in 10 oriental melons were unregistered pesticides for using in Korea. Fenbuconazole detected in 1 potato and phorate detected in 1 tomato were exceeded over the MRLs established by Korea Food and Drug Administration. CONCLUSION: Based on these results, a risk assesment was conducted using a percentage of acceptable daily intake(%ADI). %ADI ranged from 0.0064% to 4.6035%, and showed these values have no effect on human health.
