This study was carried out to survey the levels of mercury in root vegetables and assess dietary exposure / risk to the Korean population health. Various samples including Panax ginseng C.A mayer, Codonopsis lanceolata, and Platycodon granditloum were collected from markets across Korea. The concentrations of mercury were measured using automatic mercury analyzer. The analytical and sampling methods in this study were full validated. The mercury content in root vegetables was determined below 100 μg/kg (maximum residue of mercury for salt established in Korea). For risk assessment, probable daily intake was calculated and compared with PTWI (tolerable weekly intake) established by JECFA. The level of overall exposure to mercury for Korean through root vegetables was below 1% of the recommended JECFA levels, indicating of little possibility of risk. Whereas, MFDS was conducted to assess the dietary exposure to mercury from food intake, based on several reports regarding mercury published by MFDS in the 2000s. The mean and 95th percentile for exposure to dietary mercury were 4.29 and 12.48 μg/day, corresponding to 13.6% and 39.7% of PTWI, respectively.
