Abstract
BACKGROUND: This study was carried out to survey the levels of heavy metals in perennial root vegetables and to assess dietary exposure and risk to the Korean population health.METHODS AND RESULTS: Perennial root vegetables (n=214) including Panax ginseng C.A mayer, Woodcultivated ginseng, Codonopsis lanceolata, and Platycodon granditloum were collected from markets or harvested from farmhouse in Korea. Lead(Pb), cadmium(Cd) and arsenic (As) analysis were performed with microwave device and inductively coupled plasma mass spectrometer. Limit of detection for heavy metals were 0.010~0.050 μg/kg, while limit of quantitation were 0.035~0.175 μg/kg. The recovery results were in the range of 76~102%. The average contents of heavy metals in perennial root vegetables were in the range of Pb 0.013(Panax ginseng C.A Mayer)~0.070 (Wood-cultivated ginseng) mg/kg, Cd 0.009(Panax ginseng C.A Mayer)~0.034(Codonopsis lanceolata) mg/kg, and As 0.002(Panax ginseng C.A Mayer)~0.004(Plafycodon grandiflorum) mg/kg, respectively. For risk assessment, daily intakes of heave metals were estimated and risk indices were calculated in comparison with reference dose. The dietary exposures of heavy metals through usual intake were Pb 0.070 μg/day, Cd 0.041 μg/day and As 0.008 μg/day, taking 0.03%, 0.08% and 0.0003% as risk indices, respectively.CONCLUSION: The risk level for Korean population exposed to heavy metals through intake of perennial root vegetables was far low, indicating of little possibility of concern.
