What about manganese poisoning?

First: what is the allowable content of manganese in drinking water? According to the hygienic standard of drinking water in China, the content of manganese should not exceed 0.1mg/l. When the mass concentration of manganese exceeds 0.1mg/l, the drinking water will give off an unpleasant taste, and the utensils and washing clothes will be colored.

Second: how do ordinary people know that manganese in drinking water (non tap water, such as groundwater, well water, etc.) exceeds the standard? When the water reaches 1.0 mg per kilogram, the color of water will increase and there will be obvious metal smell. Beyond this limit, the water will produce reddish brown sediment and leave yellow spots on white fabrics, water containers and sanitary appliances.

Third: can drinking water with excessive manganese be used for bathing? It can be used for any domestic water except for food (drinking, cooking, washing vegetables, etc.), such as bathing, washing clothes, etc. because the absorption of manganese through the skin is very small, it will not affect the body.
