Industrial salt - sodium nitrite

1. Nitrite has a destructive effect. After it enters the body, it can turn the oxygen-carrying low iron hemoglobin in the body into methemoglobin. When methemoglobin encounters oxygen, it is firmly combined and difficult to separate. In this way, the whole body tissues of the human body will be deprived of oxygen, especially the brain, which has the most serious impact on the human body.

When the human body ingests 0.3 to 0.5 grams of sodium nitrite, it can cause acute poisoning, and 3 grams can cause death. Once the human body is poisoned, the disease can occur within ten minutes.

2. Due to hypoxia, dizziness, head fullness, tinnitus, general weakness, numbness of hands and feet, nausea and vomiting, diarrhea, cyanosis, heart palpitations, drop in blood pressure, difficulty breathing and other symptoms may occur, which are serious. Convulsions and coma may occur. If rescue is not performed in time, or excessive intake occurs, respiratory and circulatory failure may result in death.

3. Most cases of poisoning are caused by mistakenly taking sodium nitrite as table salt, table sugar, edible alkali, etc. In addition, after vegetables stored for a long time at high temperatures become spoiled, the sodium nitrite content in the vegetables will also increase significantly. When people suffer from sodium nitrite poisoning, they should be sent to the hospital for rescue immediately without delaying the opportunity.

4. Consumption of industrial salt can lead to iodine deficiency in the human body, gastrointestinal dysfunction, damage to the nervous system, including big neck disease, and in severe cases, poisoning; and big neck disease is mainly caused by long-term consumption. Caused by fake salt that does not contain iodine;

In addition, because industrial salt has many impurities and excessive heavy metals, it is particularly harmful to pregnant women and children, and can lead to reduced intelligence in children and poor fetal development in pregnant women. .

Extended information:

It is widely used in industry and is one of the most basic raw materials in the chemical industry. It is called the "mother of the chemical industry". Among the main products of the basic chemical industry, hydrochloric acid, caustic soda, soda ash, ammonium chloride, chlorine, etc. are mainly produced using industrial salt as raw materials. Large amounts of sodium chloride are required in the organic synthesis industry.

In addition, it is also used in soap manufacturing, ceramics, glass production, daily chemicals, oil drilling, drilling working fluids, completion fluids, petrochemical dehydration fluids, early strength agents in the construction industry, and the solidification of production coatings. Agents, latex coagulants in the rubber industry, additives in the paper industry and waste paper deinking, inorganic chemical raw materials and sulfate removal agents in the chemical industry, coagulants for sodium alginate, prevention and control of rot in wheat, apples, cabbage, etc. and food preservatives , Preparation of metallic sodium and other sodium compounds, steel heat treatment media, etc.
