Sodium nitrite poisoning has always been a safety issue that we pay close attention to. In addition to food poisoning, the harm of sodium nitrite in various environments is incalculable. Only 3g of sodium nitrite can cause death.
Sodium nitrite poisoning has always been a safety issue that we pay close attention to. In addition to food poisoning, the harm of sodium nitrite in various environments is incalculable. Only 3g of sodium nitrite can cause death. We need to start from daily life and understand some detoxification methods for sodium nitrite poisoning, in order to avoid sodium nitrite poisoning and ensure our own safety.
There are usually several methods
1. Oxidation method: By utilizing the oxidizing properties of nitrite ions, NO2- in the medium will change the valence state of nitrogen and undergo electron gain and loss when exposed to oxidants, resulting in oxidation. NO2- ions will transform into less toxic or even non-toxic substances.
2. Reduction method: Utilizing the oxidizing property of NO2- under acidic conditions, a certain reducing agent is used to reduce and degrade NO2- into volatile gases that automatically detach from the reaction system, resulting in complete denitrification and high degradation rate.
3. Physical adsorption method: using substances with high adsorption capacity, such as zeolite powder, silica gel, activated carbon, sepiolite and other adsorbents, to adsorb nitrite ions in their structure.
4. Accelerated plant growth method: Nitrite is rich in nitrogen fertilizer, and the resulting fertilizer and water are the basic nutrients for algae growth and reproduction. It can accelerate the growth and reproduction rate of algae in water and effectively reduce the concentration of nitrite.
5. Bacterial decomposition method: using nitrifying and denitrifying bacteria, under oxidative conditions, nitrifying bacteria decompose sodium nitrite and convert it into sodium nitrate; Denitrifying bacteria reduce nitrite to N2 or nitrogen oxides, reducing the overall content.
6. Water exchange method: In production, sodium nitrite is washed away by changing the water to control the content of nitrite.
7. Microbial method: Utilizing photosynthetic bacteria, Bacillus subtilis, EM bacteria, lactic acid bacteria, actinomycetes and other microorganisms to absorb sodium nitrite, restore the microecological environment, and ensure the normal cycle of nitrification and denitrification.
8. Garlic and Vitamin Detoxification Method: Eat more garlic and vitamins in your daily diet, try to clean them when eating out or buying takeout ingredients, and pay attention to preventing poisoning before and after meals.
If sodium nitrite is accidentally ingested, it can be mainly treated by inducing vomiting, gastric lavage, and drug detoxification, as follows:
1. Vomiting: For conscious patients, vomiting should be immediately induced by stimulating the throat with fingers, drinking plenty of water, and avoiding vigorous exercise.
2. Gastric lavage: If the patient is not conscious, gastric lavage should be performed in a timely manner. Potassium permanganate should be used for gastric lavage, sodium nitrite should be neutralized, and then magnesium sulfate should be used for enema to promote metabolism and eliminate toxins in the body.
3. Drug detoxification: Establish a venous fluid pathway, administer oxygen, and administer the specific detoxifying agent methylene blue for detoxification treatment. Vitamin C drugs can also be administered to accelerate detoxification and promote the reduction of methemoglobin.
Therefore, when patients experience symptoms of poisoning such as dizziness, headache, nausea, vomiting, numbness in the mouth and tongue, limb twitching, abdominal pain and diarrhea, difficulty breathing, etc. after ingesting sodium nitrite by mistake, they must be promptly sent to the hospital for treatment. They should not blindly eat food to detoxify themselves and avoid endangering their lives.
