What is the high nitrogen content of water and what is the harm to the human body

The amount of nitrogen in boiling water is related to health, it is recommended that you let the water boil for 3 minutes before drinking, because, the freshly boiled water still contains chlorine (most cities in China use chlorine for disinfection), drinking it is not good for people, 3 minutes later, the chlorine is evaporated by high temperature, so it is good for people to drink. Second, don't drink the boiling water in the water dispenser, because it is repeatedly boiled water, which contains nitrite, nitrite is a strong carcinogen, such as sodium nitrite, this thing is industrial salt, 5 grams can poison you, if you drink nitrite water for a long time, it will cause great harm to your body, the chemical formula of nitrite is Xno2 (X stands for metal substances such as sodium, potassium, calcium, etc., n is nitrogen).

Neonatal mutagenic nitrogen-containing disinfection by-products in drinking water. Disinfection by-products (DBPS) refer to the compounds formed by the reaction of disinfectants used for drinking water disinfection with some natural organic matter (NOM) or inorganic substances (bromide iodide) in drinking water. Studies of DBPS in drinking water have found that chlorine, when used as a disinfectant, not only causes olfactory and gustatory reactions, but also produces a special class of compounds, trihalomethanes, which pose a carcinogenic risk.

Therefore, the state has become more and more strict on this regulation, so that drinking water manufacturers have to change the original disinfection process, thus greatly reducing its content, but increasing the concentration of nitrogen disinfection by-products (DBPS). At present, there is no unified detection and analysis method at home and abroad.

Health hazards: The nitrogen content in the air is too high, which reduces the partial pressure of oxygen in the inhaled air, causing hypoxic asphyxia. When the concentration of inhaled nitrogen is not too high, the patient initially feels chest tightness, shortness of breath, and weakness; This is followed by irritability, extreme excitement, running around, shouting, trance, and unsteady gait, which is called "nitrogen tincture", and can enter a state of lethargy or coma.

When inhaled at high concentrations, patients can quickly fall unconscious, die due to respiratory and cardiac arrest. When the diver is deep replaced, the anesthetic effect of nitrogen can occur; If you move too quickly from a high-pressure environment to an atmospheric pressure environment, nitrogen bubbles will form in the body, compressing nerves and blood vessels or causing microvascular blockage, causing "decompression sickness" to occur.

Nitrogen is what we call nitrogen, chemicals. Very simply, too many chemicals are definitely not good for the human body, they will damage the body's organs, and chemical chronic poisoning will occur.

Depending on what type of nitrogen it is, nitrogen N2 is very small in water, and it certainly has no effect. The nitrogen in vegetable soup is the nitrogen in amino acids, which is nutrition. The nitrogen in nitrite is toxic.

Harmful to health, if there is no that, how can the nitrogen-containing substances in the exhaust of the car pollute nature.

I don't think there's any harm, it's everywhere in nature, and humans can absorb as much as they need, and take as much as they can out of the body.

Nitrogen does not contain water because pure nitrogen is insoluble in water.

Nitrogen is a colorless and odorless gas, and its density is kilograms and cubic meters. Because its molecule is formed by two nitrogen atoms sharing three electron pairs, this combination is very stable and not easy to destroy, so the chemical properties of nitrogen are relatively stable and cannot be burned or supported by combustion. It can be used as a protective gas.

Nitrogen and oxygen need to be discharged to produce colorless nitric oxide.

Gas, nitric oxide, like nitrogen gas, is also a colorless and odorless gas that is insoluble in water, and is a non-salt oxide.

At high temperatures, high pressures, or with catalysts, nitrogen and hydrogen react and they combine to form ammonia.

At present, the pollution of surface water in China is serious, and most of the drinking water sources are polluted by ammonia nitrogen.

Higher concentrations of ammonia nitrogen in raw water indicate new organic contamination of the water body, and ammonia nitrogen in drinking water can lead to nitrite problems and smell problems at the end of the network.

At present, most countries in Europe have strict regulations on the concentration of ammonia nitrogen in drinking water.

China also has a similar limit for the concentration of ammonia nitrogen in drinking water sources, but the current drinking water standard GB 5749-85 used by waterworks does not stipulate ammonia nitrogen, and the standard for controlling the concentration of ammonia nitrogen in drinking water should be gradually implemented.

The fundamental way to solve the problem of ammonia nitrogen in drinking water is to control water pollution, but in the case of poor pollution control, only to strengthen the decontamination capacity of the waterworks, biological pretreatment technology is the most effective and economical way to solve the problem of ammonia nitrogen in drinking water.

Under the current economic conditions in China, it is difficult to implement the general requirement to treat ammonia nitrogen in water, but we still hope to gradually implement the removal of ammonia nitrogen in water in conditional waterworks or water plants whose raw water is seriously polluted by ammonia nitrogen, and gradually promote this requirement.
