What catalyst is used for weather modification? Will it pollute the environment?
In the world, artificial precipitation enhancement mainly uses artillery shells, rockets, airborne incendiary bombs, flame sticks containing silver iodide, etc., and the work efficiency is relatively high. The silver iodide rocket is launched into the clouds, instantly vaporized into a molecular state, and the nucleation rate is extremely high. The nucleation rate of AgI around 1g can reach the square of 13- 14 under the condition of-10. Therefore, the catalytic effect of increasing snow ratio can be achieved with less dosage. In fact, snowfall has been artificially constructed in some areas, but even if all the silver iodide catalysts used in the construction fall to the ground, the silver iodide content per square kilometer is only 0.21g. According to the precipitation calculation, the silver ion concentration is about 0.000035 mg/L, which is far lower than the requirements of the World Health Organization standard and China's national drinking water hygiene standard that the silver content should not exceed 0.05 mg/L, which will not cause pollution to the ecological environment.
Scientific research institutions began to study the impact of silver iodide catalyst on the environment. According to the detection data of precipitation and soil in the United States, Spain, Greece, Australia, Russia and other countries, the average concentration of silver ions is very low. Therefore, silver iodide, a catalyst for weather modification, can ignore the adverse impact on the ecological environment. Potassium cyanide is a well-known toxic substance, and potassium ferrocyanide contained in salt is not a substance. Potassium ferrocyanide is a low toxic substance. A person needs to eat 3-2 salts a day to have a negative impact on the human body. We normal people eat 20 grams of salt a day, which is already salty.
Scientific research shows that ultra-sensitive sulfur has no negative effects on the development, reproduction and endocrine system of human beings and other mammals. In the normal use range, ultra-sensitive sulfur has no chronic toxicity and neurotoxicity to livestock.
