甲基汞（MeHg）因其对健康的不利影响而受到全世界的关注。为探讨日本半岛地区（卡拉库瓦乔）不同亚群的甲基汞暴露负担及其潜在影响因素，进行了横断面调查。本研究包括来自102个家庭的189名个体。成年男性、女性和儿童头发总汞（THg）的几何平均值分别为5.74、3.78和2.37 μg/g，其中56.5%、30.9%和12.9%的人头发总汞（THg）超过5 μg/g。金枪鱼和鲭鱼是不同亚群中常见的与毛发THg水平正相关的鱼类（标准化系数范围为0.20 ~ 0.58,p< 0.05）。频繁食用这些鱼类和摄入大量鱼类可能是该地区甲基汞暴露的主要原因。在未来的研究中，应强调地方规模的风险评估和风险沟通。
Methylmercury (MeHg) is a worldwide concern owing to its adverse health effects. To explore MeHg exposure burdens and the potential contributing factors in different subpopulations in a peninsula area (Karakuwacho) in Japan, a cross-sectional survey was performed. This study included 189 individuals from 102 families. The geometric means of total hair mercury (THg) were 5.74, 3.78 and 2.37 μg/g for adult males, females and children, respectively, of which 56.5 %, 30.9 % and 12.9 % had hair THg exceeding 5 μg/g, respectively. Tuna and mackerel were the common fish species that were positively correlated with hair THg levels in different subpopulations (standardized coefficient ranged from 0.20 to 0.58,p< 0.05). Frequent consumption of these fish species and a large amount of fish intake are likely major contributors of MeHg exposure in this area. Local-scale risk evaluation and risk communication should be highlighted in future studies.
