锰是工业生产中应用较为广泛的原料,随着四个现代化的发展,不少生产部门的锰作业过程中对危害工人健康的职业因素采取了防护技术措施,不同程度地控制了锰中毒的发生。但是锰作业的防毒措施还不完善,因此锰仍可通过各种途径影响人体的健康。由于职业性锰中毒的发病缓慢、临床症状和体征也是逐步发展的,尤其是锰中毒的发生存在着较大的个体差异性,且临床症状与体内锰化合物的含量和排泄量又不呈平行关系,所以在锰中毒早期
Manganese is a widely used raw material in industrial production. With the development of four modernizations, many occupational factors that endanger the health of workers in the manganese production process of many production departments have taken protective technical measures to control manganese poisoning to varying degrees . However, anti-virus measures for manganese operations are not perfect, so manganese can still affect human health through various channels. Due to the slow incidence of occupational manganese poisoning, clinical symptoms and signs are also gradually developed, especially the incidence of manganese poisoning there is a large individual differences, and the clinical symptoms and the amount of manganese compounds in vivo and excretion is not parallel , So early in the manganese poisoning
