长期接触锰的烟尘将引起以神经系统改变为主的职业性慢性锰中毒性疾病。人发因其取样容易,保存方便,微量元素含量比较高,且能反映环境对人体的污染程度和人体代谢情况,已被作为一种理想的活体组织检查材料。对于职业性慢性锰中毒的诊断,发锰不失为一项有用的接触指标。目前,有关人发中铁、铜、锌、钙、镁等微量元素的测定方法及研究报告较多,而有关头发中锰含量测定方法的报道却不多见。本文参考有关资 Prolonged exposure to manganese fumes will cause occupational chronic manganese toxic diseases that predominate in the nervous system. Human hair because of its easy sampling, convenient storage, trace element content is relatively high, and can reflect the degree of environmental pollution on the human body and human metabolism, has been used as an ideal biopsy material. For the diagnosis of occupational chronic manganese poisoning, hair manganese is a useful indicator of contact. At present, there are many methods and research reports on the determination of trace elements such as iron, copper, zinc, calcium and magnesium in human hair. However, reports on the determination of manganese in hair are rare. This article refers to the funding
