What are the side effects of silver iodide?

“Exposure to silver can lead to argyrosis, methemoglobinemia, anxiety, seizures, and cardiac arrest.” Scientists also say people who inhale a lot of silver iodide risk permanent lung damage, aka Silver Lung. Because it’s delivered in such small doses right now, the negative effects of silver iodide are minimal.

What is silver iodide used for?

Silver iodide or dry ice (solid carbon dioxide) is used to supply naturally deficient clouds with the proper concentration of ice crystals to increase rainfall through the ‘cold rain’ process.

Is silver iodide carcinogenic?

The US Public Health Service claims there is a negligible environmental impact by cloud seeding. That said, silver iodide when studied in labs is a different story all together and is indeed toxic and dangerous. This same study says that silver is not known to be carcinogenic to humans.

Is silver iodide toxic to aquatic life?

The silver ion is among the most toxic of heavy metal ions, particularly to microorganisms and to fish. Inhibition of aquatic microorganisms would interfere with the cycle that returns essential nutrients to the water. Ag in air and water should be regularly monitored. Iodine in AgI poses no environmental danger.

Is cloud seeding toxic?

With an NFPA 704 health hazard rating of 2, silver iodide can cause temporary incapacitation or possible residual injury to humans and other mammals with intense or chronic exposure. However, there have been several detailed ecological studies that showed negligible environmental and health impacts.

Why do you rinse silver iodide with water?

Filtration separates insoluble substances from liquids and solutions. The precipitate is insoluble in water, so any remaining contaminating solution can be removed by washing it with distilled water.

What is silver iodide made from?

Silver iodide is prepared by reaction of an iodide solution (e.g., potassium iodide) with a solution of silver ions (e.g., silver nitrate). A yellowish solid quickly precipitates. The solid is a mixture of the two principal phases.

What is the toxicity level of silver?

Silver exhibits low toxicity in the human body, and minimal risk is expected due to clinical exposure by inhalation, ingestion, dermal application or through the urological or haematogenous route.

Is silver iodine flammable?

Non-combustible, substance itself does not burn but may decompose upon heating to produce irritating, corrosive and/or toxic fumes. Extinguishing Media: Substance is noncombustible; use agent most appropriate to extinguish surrounding fire. Use water spray, dry chemical, carbon dioxide, or appropriate foam.
