The harm of ammonia to the human body, is ammonia toxic, and what are the harms

If the environment with high concentration of ammonia is present, the human body will have symptoms such as tearing, sore throat, dyspnea, chest tightness, cough, nausea, vomiting, and even stop breathing and heartbeat in severe cases. After ammonia enters the human body, it can combine with hemoglobin to reduce the oxygen-carrying capacity of hemoglobin and reduce oxygen saturation.

The harm of ammonia is mainly reflected in the fact that ammonia is easily inhaled into the blood through the alveoli, combines with hemoglobin, and destroys the oxygen transport function. After inhaling a large amount of ammonia in a short period of time, tearing, sore throat, hoarseness, cough, bloody sputum, chest tightness, dyspnea, dizziness, headache, nausea, vomiting, fatigue, etc. may occur.

When the (volume) concentration of ammonia in the air is reached, a person staying in it for half an hour will cause poisoning; When the concentration reaches 11-14%, it can be burned; When the concentration reaches 16 25%, it can be caused by open flame.

In addition, ammonia will decompose hydrogen (H2) at high temperatures (260 cracks), which will produce strong ** when exposed to air and open flames.

Preparation method: Most of the industrial ammonia production is produced by the synthesis of nitrogen and hydrogen under high pressure, high temperature and in the presence of circulating agents. Nitrogen is mainly found in air; Hydrogen is mainly used in syngas containing hydrogen and carbon monoxide (pure hydrogen is also used in the electrolysis of water).

The mixture of nitrogen and hydrogen is the raw gas for ammonia synthesis. The feed gas from the fuel chemical industry contains sulfur compounds and carbon oxides, which are toxic substances to the catalyst for ammonia synthesis and must be purified before ammonia synthesis.

Ammonia is inhaled into the human body, and a small part of the du is divided into carbon dioxide said to neutralize, and the rest of the qi enters the bloodstream, mainly with.

DAO hemoglobin binds, back.

Destroys the function of blood oxygen transport.

After inhaling a large amount of ammonia in a short period of time, tearing, sore throat, cough, chest tightness, dyspnea, dizziness, vomiting, fatigue, etc. If too much ammonia is inhaled, resulting in a high concentration of ammonia in the blood, it will cause cardiac arrest and respiratory arrest through the reflex action of the trigeminal nerve endings, which is life-threatening.

Ammonia in indoor air mainly comes from concrete additives used in building construction. The additives contain a large amount of ammonia substances, which are reduced to ammonia gas and released in the wall with changes in environmental factors such as temperature and humidity. Even this harm will directly affect the next generation.
