In fact, in our lives, there have been many cases that the water quality has been polluted and excluded into the water body without treatment, which has caused very serious consequences, not only affecting the ecological cycle but also harming the human body. In this chapter, water quality online monitoring instrument manufacturers will work with you to understand the harm caused by excessive manganese in water!

What is the Standard for Manganese in Water?

Under the sanitary standard of drinking water in China, the content of manganese in water shall not exceed 0.1mg/L. When the mass concentration of manganese exceeds 01mg/L, it will make drinking water smell, and it will stain utensils and washing clothes. When the water reaches 1.0mg per kilogram, the color of the water will increase, and there will be a distinct metallic taste, beyond this limit, the water will produce reddish-brown precipitates, and can leave traces of yellow on white fabrics or water utensils and sanitary utensils.

What are the Hazards of Excessive Manganese in Water?

Too much iron and manganese in the human body has an impact on the heart, it will affect the central nervous system, and excessive intake will have an impact on intelligence and reproductive function. According to the human body’s tolerance to manganese, the human body can tolerate 10mg of manganese per day, once it exceeds this value, it will cause harm to the body. (Research by Finnish scientists in the United States has proved that)

Excessive manganese content can cause chronic poisoning, common oral concentration of 1% potassium bornate solution, accompanied by oral mucosal erosion, nausea, vomiting, stomach pain; 3% ~ 5% solution caused gastrointestinal mucosal necrosis, causing abdominal pain, hematochezia, and even shock; 5 to 19g of manganese can be fatal. Sore throat, cough, shortness of breath, and sudden chills and high fever may occur when welding under poor ventilation and inhaling a large amount of new manganese oxide smoke. Chronic manganese poisoning generally develops after 3 to 5 years or more of exposure to manganese smoke and dust.

Knowing the harm caused by excessive manganese in water, relevant personnel have to pay attention to the use of T8000-Mn total manganese online analyzer for real-time monitoring of manganese in water to judge the change of water quality.
