Total mercury (TM) is a hazardous element that is of particular concern to human health. Due to the diversity of dietary habits among fishes, tissue-specific analysis of hazardous elements is necessary. In this study, the tissue-specific TM in cultured fish was analyzed to conduct risk assessment. The highest concentrations of TM were found in the farmed marine fish Pagrus major (0.111 mg/kg) and in the farmed freshwater fish Channa argus (0.162 mg/kg). TM concentration was significantly correlated with total fish length (P<0.01). Significant differences in TM were found between three types of fish tissue, with the concentration in fish muscle being significantly higher than those of gill or liver (P<0.01). Moreover, the tissue-specific TM concentrations of farmed freshwater fish were significantly higher than those of farmed marine fish (P<0.01). According to the risk assessment, the TM body exposure rate of muscle and liver in cultured fishes ranged from 0.001 to 0.389% of the Provisional Tolerable Weekly Intake. Therefore, these results showing the tissue-specific TM contents of cultured fish could be useful to assess the health risks of Korean dietary habits.
