Reports on the occurrence and intake assessment of mercury for Korean seafood are currently not available. This is the first report to estimate the intake of methyl (Me-Hg) and total mercury (T-Hg) from seafood consumption in Korea. The concentrations of Me-Hg and T-Hg in seafood ranged from 1.02 to 780 (mean: 55.6) ng g(-1) wet weight and 4.89 to 1008 (mean: 100) ng g(-1) wet weight, respectively. The residue levels of Me-Hg and T-Hg in Korean seafood were moderate compared with those found in other countries. The methylation ratios of fish, cephalopods and crustaceans were similar, but shellfish had lower values compared with other species. The intakes of Me-Hg and T-Hg from seafood consumption for the general population were estimated to be 38.8 and 73.8 ng kg(-1) body weight per day, respectively. Mackerel, tuna and squid made the highest contributions to the total intake of these contaminants. Among eight age groups, 30-49 year and 3-6 year age groups had the highest exposure to Me-Hg and T-Hg. The concentrations and intakes of Me-Hg and T-Hg from Korean seafood were less than the allowable residue levels and threshold intake levels suggested by Korean and international authorities. The present study may be useful for risk management of mercury in Korean seafood.
目前尚无关于韩国海产品汞的发生情况和摄入量评估的报告。这是第一份估算韩国海产品消费中甲基汞（Me-Hg）和总汞（T-Hg）摄入量的报告。海产品中Me-Hg和T-Hg的浓度分别为湿重1.02至780（平均：55.6）ng g(-1)和4.89至1008（平均：100）ng g(-1)。与其他国家相比，韩国海产品中Me-Hg和T-Hg的残留水平处于中等水平。鱼类、头足类动物和甲壳类动物的甲基化率相似，但贝类与其他物种相比甲基化率较低。一般人群通过海产品消费摄入的Me-Hg和T-Hg估计分别为每天38.8和73.8 ng kg(-1)体重。鲭鱼、金枪鱼和鱿鱼对这些污染物的总摄入量贡献最大。在八个年龄组中，30-49岁和3-6岁年龄组对Me-Hg和T-Hg的暴露量最高。韩国海产品中Me-Hg和T-Hg的浓度和摄入量低于韩国和国际权威机构建议的允许残留水平和阈值摄入水平。本研究可能有助于韩国海产品汞的风险管理。
