What are the hazards of silver nitrate to human body

When it comes to silver nitrate, the first thing that comes to mind is that it is a chemical substance that appeared in high school chemistry textbooks. Generally speaking, as a transparent crystal, people may ignore it and not pay much attention to it in their daily lives. But in real life, the harm of silver nitrate to the human body cannot be ignored. How much do you know about this? Let’s take a look at it together.

Silver nitrate is a strong oxidant, corrosive, and environmental pollutant. It may burn or explode when mixed with some organic matter or sulfur and phosphorus, ground or impacted; silver nitrate is corrosive. Once the skin comes into contact with silver nitrate solution, black spots will appear, which is due to the production of black silver protein. Silver nitrate is toxic, with an LD50 of approximately 50 mg/kg and a lethal dose of approximately 10 grams. Silver nitrate is somewhat toxic and can cause severe corrosion to the gastrointestinal tract once it enters the body. The lethal dose for an adult is about 10 grams. Median lethal dose (mouse, oral) 50 mg/kg.

Accidental ingestion of silver nitrate can cause severe abdominal pain, vomiting, bloody stools, and even gastrointestinal perforation. Can cause skin and eye burns. Workers who are exposed to this product for a long time may develop systemic argyria. Symptoms include: widespread pigmentation of the skin all over the body, which is gray-blue-black or light slate-colored; silver deposits in the eyes causing eye damage; silver deposits in the respiratory tract causing chronic bronchitis, etc. In case of skin contact, remove contaminated clothing and rinse skin thoroughly with soap and water.

Through the above introduction to silver nitrate, everyone can clearly realize that this is a chemical substance that we often overlook in our lives. We need to pay enough attention to the harm of silver nitrate to the human body, and its corrosiveness warns us not to touch it casually. Workers in industrial production enterprises should pay more attention to protecting their personal safety. When encountering such corrosive substances, they need to master some cleaning knowledge.
