What are the hazards of manganese to the human body

Manganese is a metallic element and a transition metal, but it will oxidize if it is in a humid environment. Manganese ore is very abundant in my country and is mainly used in steelmaking and alloys. General manganese is an enzyme with important physiological functions in our body. Many occupations related to manganese generally have certain effects on the body. So what kind of effects do they have? Let’s take a look at the harm of manganese to the human body.

Manganese poisoning: Manganese is a grayish white, hard, brittle and shiny metal. Manganese is widely present in nature. The soil contains 0.25% manganese, and tea, wheat and hard-shelled fruits contain more manganese. Jobs involving exposure to manganese include stone crushing, mining, electric welding, production of dry batteries, and the dye industry. Manganese is one of the essential trace elements for the normal body. It constitutes several enzymes with important physiological functions in the body. The normal daily intake of manganese from food is 3-9 mg.

Some people have reported that manganese poisoning was found in patients with impaired liver function, obstructed bile duct, or both. The patients' brain MRI examinations showed obvious abnormalities, which improved as the poisoning was alleviated. In addition, although there is no definite conclusion on the issue of oral toxicity, there are some reports suggesting that this issue deserves full attention and research. For example, it has been found that people with neurological dysfunction have higher than normal manganese concentrations in their brains; people who engage in violent behavior have been found to have higher than normal manganese levels.

Obvious extrapyramidal damage manifests as Parkinson's syndrome: increased muscle tone of the limbs, accompanied by resting tremor, which can induce cogwheel rigidity; and movement disorders such as inflexibility and inaccuracy in finger or rotation tests, positive standing sign with eyes closed, speech disorders, or abnormal gait, difficulty in walking backward, etc.

Toxic psychosis has significant mental and emotional changes, such as emotional indifference, slow reaction, involuntary crying and laughing, obsessive thoughts, impulsive behavior, etc.

The above content tells us the harm of manganese to the human body. We know very little about metal elements, but many metal elements are helpful to the body, but they can also be harmful. Therefore, we should learn more about metal elements so that we can avoid some harm to the body. We still need to learn more knowledge to enrich our knowledge.
