头发样本从日本的几个社会经济和种族群体中收集，从印度的两组（素食者和非素食者）中收集。分析了样品中总汞和甲基汞的含量。在接触汞蒸气的钼冶炼厂工人的头发中检测到大量的汞。然而，他们体内的甲基汞含量几乎在正常范围内。这表明，在头发样本中发现的汞含量异常可归因于他们所接触的汞污染。另一方面，在水俣病患者的头发中检测到大量汞，该人群头发样本中甲基汞与总汞的比例明显高于重度汞暴露的汞工人。这是水俣患者通过摄入鱼类通过胃肠道吸收甲基汞的证据。本报告认为，食用鱼类的数量会显著影响头皮头发中的汞含量，特别是甲基汞含量。因此，迫切需要进一步研究实际或潜在的健康危害，特别是在自然环境中捕获的海洋产品中所含的低水平烷基汞。还强调了确定生物标本中甲基汞与总汞的比例对于评估汞吸收的重要性。这意味着，头发标本中汞含量的重要性不应仅通过汞总量来评估；确定甲基汞与总汞的比例是必要的。
Hair samples were collected from several socioeconomic and ethnic groups in Japan and from 2 groups (vegetarians vs nonvegetarians) in India. The samples were analyzed for the amount of total mercury and methylmercury. A large amount of mercury in the hair of molybdenum refinery workers who were exposed to mercury vapor was detected. However, the amount of methylmercury in them was almost in the normal range. This suggests that the abnormal amount of mercury found in hair samples can be attributed to the mercurial contamination to which they have been exposed. On the other hand, a large amount of mercury was detected in the hair of Minamata patients and the ratio of methylmercury to total mercury in hair samples from this group was significantly larger than that in mercury workers who had heavy mercury exposure. This is evidence that the Minamata patients absorbed methylmercury by the gastrointestinal route through the ingestion of fish. It is suggested in this report that the amount of fish consumed significantly influences the mercury content in scalp hair, particularly the methylmercury content. Consequently, the actual or potential health hazards, particularly from a low level of alkylmercury contained in marine products caught in a natural environment, urgently require further study. The importance of determining the ratio of methylmercury to the total mercury in biological specimens for an assessment of mercury absorption is also emphasized. This means that the significance of the amount of mercury in hair specimens should not be evaluated merely by the total amount of mercury; determination of the ratio of methylmercury to total mercury is necessary.
