AB  - BACKGROUND: Studies on the risk of mercury (Hg) in Korean fishery products focus 
      primarily on total Hg levels as opposed to methylmercury (MeHg) levels. None of 
      the few studies on MeHg in tuna investigated tuna from Japanese restaurants. Few 
      have evaluated lead (Pb), cadmium (Cd) and arsenic (As) in tuna. Thus, this study 
      aimed to conduct a risk assessment by evaluating heavy metal concentrations in 
      tuna from Japanese restaurants. METHODS: Thirty-one tuna samples were collected 
      from Japanese restaurants in the Republic of Korea. They were classified 
      according to region and species. The concentration of heavy metals in the samples 
      was analyzed using the Ministry of Food and Drug Safety Food Code method. The 
      rate of exceedance of maximum residue levels (MRLs) and the risk compared to the 
      provisional tolerable weekly intake (PTWI) set by the Joint Food and Agriculture 
      Organization/World Health Organization Expert Committee on Food Additives (%PTWI) 
      were evaluated for risk assessment. RESULTS: The mean of MeHg, Pb, Cd and As 
      concentrations were 0.56 +/- 1.47 mg/kg, 33.95 +/- 3.74 mug/kg, 14.25 +/- 2.19 mug/kg and 
      1.46 +/- 1.89 mg/kg, respectively. No sample exceeded the MRLs of Pb and Cd, but 
      9.7% of the samples exceeded the MRL of MeHg. The %PTWIs of MeHg, Pb, Cd and As 
      were 4.2037, 0.0162, 0.0244 and 1.1627, respectively. The %PTWI of MeHg by age 
      group and sex was highest among men aged 19-29 years (10.6494), followed by men 
      aged 30-49 years (7.2458) and women aged 19-29 years (4.8307). CONCLUSIONS: We 
      found that 3 out of 31 samples exceeded the MRL of MeHg. The %PTWI of MeHg showed 
      significant differences based on age and sex, and the value was likely to exceed 
      a safe level depending on individuals' eating behaviors. Therefore, improved risk 
      management for MeHg is required.
