The effects and hazards of nitric oxide

As we grow older, much of the knowledge we have learned is basically forgotten and returned to the teachers. It is very difficult to tutor our children in their studies. We always feel that the knowledge is both familiar and unfamiliar, which is very frustrating. Nitric oxide is a chemical knowledge that we learned when we were in the introductory stage of chemistry. Sometimes when children ask people about the effects and hazards of nitric oxide, people are often confused and find that they don't remember it at all.

Nitric oxide acts as a messenger molecule. When the endothelium wants to tell muscles to relax and improve blood flow, it produces molecules of nitric oxide, which are small enough to easily cross cell membranes. The smooth muscle cells around the blood vessels relax after receiving the signal, causing the blood vessels to dilate.

Nitric oxide also works in cells of the nervous system. Its effect on peripheral nerve endings. The brain sends messages through peripheral nerves to provide corresponding nitric oxide to the blood vessels in the perineum, causing blood vessels to dilate, increasing blood flow, and thus enhancing erectile function. In some cases, weak erections are caused by less nitric oxide being produced by the nerve endings. "Viagra" can expand the effectiveness of nitric oxide, thereby enhancing erectile function.

NO has a low solubility in water and does not react with water. At room temperature, NO can be easily oxidized to nitrogen dioxide, and can also react with halogens to generate halogenated nitrosyl (NOX), such as NO+Cl2=2NOCl. The nitric oxide molecules produced by the immune system can not only fight against microorganisms that invade the human body, but also to a certain extent prevent the reproduction of cancer cells and the spread of tumor cells.

Health Hazards: This product is unstable and quickly turns into nitrogen dioxide in the air, causing irritation. Nitrogen oxides mainly damage the respiratory tract. In the initial stage of inhalation, there are only mild eye and respiratory tract irritation symptoms, such as throat discomfort and dry cough. Delayed pulmonary edema and adult respiratory distress syndrome often occur after an incubation period of several hours to more than ten hours or longer, with symptoms such as chest tightness, respiratory distress, cough, foamy sputum, cyanosis, etc. May be complicated by pneumothorax and mediastinal emphysema. Delayed obstructive bronchiolitis may occur about two weeks after pulmonary edema subsides. High concentrations of nitric oxide can cause methemoglobinemia. Chronic effects: Mainly manifested as neurasthenia syndrome and chronic respiratory inflammation. Pulmonary fibrosis occurs in some cases. Can cause tooth erosion.

Environmental hazards: Harmful to the environment and may cause pollution to water, soil and air.

Explosion hazard: This product is combustible, toxic and irritating.
