What is Fluorosis?

Fluorosis is a chronic systemic disease with early symptoms such as fatigue, loss of appetite, dizziness, headache, and memory loss. After excessive fluorine enters the human body, it is mainly deposited on teeth and bones, forming fluorosis and fluorosis.

Fluorosis

Fluoride stained teeth show white opaque spots on the tooth surface. After the spots are enlarged, the teeth lose their luster, and when they are obvious, they show yellow, tan, or dark brown spots. In severe cases, shallow sockets or pattern defects appear on the tooth surface, and the tooth shape is incomplete and often falls off early. ^[1]

Fluorine is one of the trace elements necessary for human life. The human body needs about 1.0 to 1.5 mg of fluorine per day, and daily intake of small doses of fluoride can promote the normal growth and development of teeth and bones, as well as the conduction of the nervous system and the normal activity of the enzyme system. Lack of fluoride can cause

Production and use of fluorine and fluoride, especially aluminum smelting, manufacturing

There is no specific cure for fluorosis. The best control measure is to change the water source. Water with higher fluorine content can also be removed by chemical drugs (such as aluminum sulfate, activated carbon, etc.). In addition, you can take flunin tablets, 2 times a day, 1 tablet each time, for 30 days as a course of treatment, it can promote the body to discharge fluoride. ^[1]

Because fluorine and fluoride are highly corrosive, in order to prevent fluorine poisoning, production pipelines and containers should use fluorine-resistant corrosion-resistant materials (such as acid-resistant ceramics, stainless steel and plastic, etc.), strengthen the safety management of storage and transportation, and have high fluorine concentration. Gas masks should be worn in all areas. The operation and production of exposure to hydrofluoric acid should be carried out under good ventilation, wear protective clothing and gloves, and pay attention to whether there are small leaks in the gloves. Contaminated clothing is washed with sodium bicarbonate solution. Contaminated tools and equipment are first neutralized with lime water and then washed with water. ^[1]

The maximum allowable concentration of hydrogen fluoride and fluoride (converted to F) in the air of the production site is 1 mg / m. Pre-employment and regular health check-ups, employment contraindications for fluoride operations are obvious cardiopulmonary disorders, neurological and skeletal disorders. In order to prevent fluorosis and fluorosis, there are certain standards for fluoride in drinking water. ^[1]
