近年来,头发与微量元素的关系受到医学和环境科学、生态学、营养学以及生物地球化学等工作者的重视。国内自七十年代起,许多学者研究了人发中微量元素的含量及其变化规律,并在探索地方病(如克山病、大骨节病、甲状腺肿、克汀病等)致病原因和采取预防措施等方面取得了较大的进展。头发犹如“录音带”,能反映过去某时期微量元素的摄入和代谢的历史。1957年Schwarz证明硒是动物体内必需的微量元素。1975年由Awasthi证明硒也是人体必需的微量元素,是人红细胞谷胱甘
In recent years, the relationship between hair and trace elements has been emphasized by medical and environmental scientists, ecology, nutrition and biogeochemistry. Since the 1970s, many scholars have studied the content and variation of trace elements in human hair and explored the etiology and application of endemic diseases (such as Keshan disease, Kashin-Beck disease, goiter, cretinism, etc.) Prevention measures have made great progress. Hair is like a “tape,” which reflects the past history of micronutrient intake and metabolism in the past. 1957 Schwarz proves that selenium is an essential trace element in animals. Awasthi in 1975 proved that selenium is also an essential trace element of the human body, is human erythrocyte glutathione
