Women of childbearing age who are susceptible to mercury exposure were studied to understand the relation between mercury intake through fish and shellfish consumption and mercury exposure indices from blood, hair, and urine samples. A total of 711 women of childbearing age from coastal areas with a high concentration of mercury exposure in Korea were studied. Data were collected on demographic characteristics, dietary intake of fish and shellfish using the simple Food Frequency Questionnaire. Mercury concentration was estimated from the collected samples of blood, hair, and urine. The geometric mean of blood methyl mercury concentration of mercury exposure through seafood was 3.06 μg/L for the low tertile, 3.12 μg/L for the middle tertile, and 3.60 μg/L for the high tertile, indicating a clear tendency of blood methyl mercury to increase as the mercury exposure by fish and shellfish intake ascended. For total blood mercury and hair mercury, the middle and high tertiles had higher values than the low. Mercury exposure through fish and shellfish intake is a main factor for an increase of blood methyl mercury concentration in women of childbearing age. More attention needs to be paid to mercury exposure through seafood intake, considering the serious effect mercury concentration has on women of childbearing age.
研究了易受汞暴露影响的育龄妇女，以了解通过食用鱼贝类摄入的汞与血液、头发和尿液样本中的汞暴露指数之间的关系。对韩国高汞暴露地区的 711 名育龄妇女进行了研究。收集了人口统计学特征、使用简单食物频率问卷的鱼贝类饮食摄入数据。从收集的血液、头发和尿液样本中估算了汞浓度。通过海鲜摄入的汞暴露的血液甲基汞浓度的几何平均值为低三分位 3.06μg/L、中三分位 3.12μg/L 和高三分位 3.60μg/L，表明随着鱼贝类摄入的汞暴露增加，血液甲基汞呈明显上升趋势。对于总血汞和发汞，中三分位和高三分位的值高于低三分位。通过食用鱼贝类摄入的汞暴露是育龄妇女血液甲基汞浓度升高的主要因素。考虑到汞浓度对育龄妇女的严重影响，需要更加关注通过食用海鲜摄入的汞暴露。
