锰是人体的必需微量元素,不仅参与蛋白质和脂肪代谢所需酶的构建,还用于体内多种酶的激活及神经递质传递的调节,对人体的生长发育、维持正常功能活动起着非常重要的作用。如果锰摄入过量,会在脑部蓄积,产生神经毒性作用。由于职业人群空气锰接触浓度高,健康危害效应容易检出,关于锰暴露健康影响的研究绝大多数围绕职业锰接触开展。除了职业接触外,锰矿石的开采冶炼、含锰产品的使用以及锰元素富集的地
Manganese is an essential trace element of the human body, not only involved in the construction of enzymes required for protein and fat metabolism, but also for the activation of many enzymes in the body and the regulation of neurotransmitter transmission, plays a very important role in the growth and maintenance of normal human body functions Important role. If excessive intake of manganese, will accumulate in the brain, resulting in neurotoxic effect. Due to the high concentration of air exposure to manganese in the occupational population, the health hazard effect is easily detected. The vast majority of studies on the health effects of manganese exposure have been conducted around occupational manganese exposure. In addition to occupational exposure, mining and smelting of manganese ores, the use of manganese-containing products, and the enrichment of manganese
