Cloud seeding has never been statistically proven to work but it is claimed to increase precipitation (Pelley, 2016).
The most common chemicals used for cloud seeding include silver iodide, potassium iodide and dry ice.
“Under the guidelines of the Clean Water Act by the EPA, silver iodide is considered a hazardous substance, a priority pollutant and as a toxic pollutant. Chronic ingestion of iodides may produce skin rashes, running nose, headache and irritation of the mucous membranes.”

“The major hazards encountered in the use and handling of silver iodide stem from its toxicologic properties. Toxic by all routes (ie, inhalation, ingestion, and dermal contact), exposure to this odorless, light yellow, crystalline substance may occur from its use in seeding clouds for rain-making…
H400 (58.62%): Very toxic to aquatic life [Warning Hazardous to the aquatic environment, acute hazard]
H410 (100%): Very toxic to aquatic life with long lasting effects [Warning Hazardous to the aquatic environment, long-term hazard]”
