Abstract

Contents of heavy metals, mercury (Hg), lead (Pb), cadmium (Cd), arsenic (As), manganese (Mn), zinc (Zn), and copper (Cu), In ginsengs and ginsengs products their safety were evaluated using a mercury analyzer, atomic absorption spectrophotometer and Inductively coupled plasma spectrometer. Contents of heavy metals in ginsengs were [min-max(mean), mg/kg]; Hg 0.002-0.02(0.007), Pb 0.018-0.39(0.106), Cd 0.004-0.413(0.106), As ND-0.094(0.013), Cu 0.24-5.5(3.2), Mn 3.18-50.4(20.09), Zn 0.76-44.27(13.42). Ginseng products values were; Hg 0.0001-0.002(0.001), Pb 0.001-0.133(0.017), Cd ND-0.07(0.004) As ND-0.181(0.008), Cu ND-1.1(0.13), Mn 0.73-30.15(1.61). Zn 0.02-13.42(1.02), similar to those reported by other countries. Average weekly Intakes of Hg, Pb and Cd from ginseng and ginseng products were 0,003, 0.01 and 0,02% of provisional tolerable weekly intake established by FAO/WHO, respectively. Our result could be utilized as important references to establish the standard of lead in ginseng and ginseng products.
