  • Mercury and methylmercury concentrations were measured in 225 marine fish samples purchased from retail markets in 5 major Korean cities in 2005. The results showed that the concentrations of mercury and methylmercury ranged from 0.006-0.455 (mean=$0.054{\pm}0.025$) mg/kg and 0.004-0.120 (mean=$0.021{\pm}0.008$) mg/kg, respectively, in fish caught from the coastal waters of the Korean Peninsula. The concentrations in deep-sea fish including tuna ranged from 0.066-2.315 (mean=$0.095{\pm}0.640$) mg/kg for mercury and 0.027-0.897 (mean=$0.281{\pm}0.182$) mg/kg for methylmercury. The estimated weekly intakes (EWIs) of mercury and methylmercury reached 3.92 and 4.70% of the provisional tolerable weekly intakes (PTWI), respectively. Consequently, the levels of mercury and methylmercury in marine fish from current retail markets do not pose any significant health risks for Koreans.

  • This study was performed to estimate daily intakes of aluminum from Platycodon grandiflorum A. De Candolle and evaluate their potential health risks for Koreans. Estimated daily intake of aluminum was calculated, whereas the actual level of aluminum in Platycodon grandiflorum A. De Candolle was analyzed using inductively coupled plasma mass spectrometry. Food consumption amount was drawn from Korea National Health and Nutrition Examination Survey (KNHANES VI-1). In analysed samples, aluminum values ranged from 0.54~564.38 mg/kg in peeled Platycodon grandiflorum A. De Candolle samples (n=53) and from 0.72~28.05 mg/kg in unpeeled ones (n=40). Statistically significant difference (P<0.001) was detected according to the type of skin. To estimate the dietary intake of Platycodon grandiflorum A. De Candolle, a total of 7,242 respondents (scenario I) were compared to 227 Platycodon grandiflorum A. De Candolle consumption subjects (scenario II). Estimated daily intake of aluminum was calculated based on point estimates. Level of safety for aluminum was evaluated by comparison with Provisional Tolerable Weekly Intake (PTWI), 1 mg/kg bw, set by the Joint FAO/WHO Expert Committee on Food Additives. For scenario I, mean estimated daily intake of aluminum was 0.001 mg/kg bw/d. For scenario II, mean estimated daily intake of aluminum was 0.033 mg/kg bw/d, and 95th percentile estimated daily intake was 0.610 mg/kg bw/d. For scenario II, aluminum from Platycodon grandiflorum A. De Candolle had a mean weekly intake that was the 23.1% of PTWI.

  • In this study we investigated the elution level of lead (Pb), cadmium (Cd), arsenic (As), zinc (Zn), nickel (Ni), antimony (Sb), germanium (Ge), aluminum (Al) and hexavalent chromium (Cr6+) from 69 home-cooking utensils into a food stimulants. The results of migration testing according to the Korea standards and specifications for utensils, containers and packages showed values the allowable migrantion limits. Al was detected in all 7 utensil materials with the average concentration ranging from 0.002-5.989 mg/L. According to the migration conditions for (180℃, 30 min), the average concentration of Al in paper was 7.2 times higher than 25℃, 10 min (P<0.05). The results of migration testing at 180℃, 30 min were also below the allowable migrantion limits. When comparing with the provisional tolerable weekly intake (PTWI) of Al, the estimated weekly intakes (EWI) accounted for 0.000-0.045% for Al.
