Abstract

|
The present study was carried out in order to assess the dietary exposure as well as the risk for lead (Pb) and cadmium (Cd) exposure through mushrooms among the Korean population. Various samples (n=536) covering 17 kinds of mushrooms were collected from retail outlets and markets in Korea. The contents of Pb were 0.005 (King oyster)-0.026 (Matsutake) mg/kg in raw mushrooms and 0.014 (Oyster)-16.411 (Manna lichen) mg/kg in dry mushrooms, respectively. The contents of Cd were 0.002 (Enoki)-0.205 (Hericium erinaciium) mg/kg in raw mushrooms and 0.021 (Vegetable worms)-2.650 (Agaricus blazei Muill) mg/kg in dry mushrooms, respectively. The mean dietary exposure of Pb for the general population was 0.053 μg/day, taking 0.03% of provisional tolerable weekly intake (PTWI). The mean dietary exposure of Cd for the general population was 0.168 μg/day, corresponding to 0.37% of provisional tolerable monthly intake (PTMI). Therefore, the level of the overall dietary exposure to heavy metals through mushroom for the Korean population was far below the recommended JECFA levels, indicating little possibility of concern.
