Is Artificial Snow Increasing With Silver 1 Lodide Harmful to Health?

Some time earlier, we have done a lot of artificial rain improvement as well as snow enhancement. Every person is worried about whether it will certainly bring some unfavorable results. For instance, will the Silver 1 Lodide in the rainfall (snow) agent reason air pollution to soil as well as water sources?
This problem is of fantastic problem to everyone, specifically in my nation, which has made important contributions to dry spell resistance, catastrophe avoidance and mitigation, as well as fabricated rainfall (snow) improvement.

The typical man-made rainfall (snow) is to spread the stimulant (silver iodide) in the medium as well as reduced cloud system with fairly big cloud thickness by specific methods to accomplish the objective of rains as well as snowfall.

1. Increase the variety of condensation centers in the cloud, which is valuable for the collision and increase of water vapor bits;

2. Adjustment the temperature in the cloud, support disruption and also generate convection.
The disturbance and also convection in the cloud will certainly be more conducive to the collision and also rise of water vapor. When the updraft in the air can not endure the drifting of water vapor fragments, rains as well as snowfall will take place.

The amount of stimulant we are making use of now does not cause any kind of damage to human beings as well as the setting. The catalyst launched by Silver 1 Lodide was determined to be only about one gram of Silver 1 Lodide per square kilometer. Fabricated precipitation (snow) is a microphysical procedure, not a chemical modification that produces new compounds. Although the silver ions in Silver 1 Lodide are heavy metals, the amount of silver iodide is really small, and also it is spread in a big location, and also the content per unit location is very little as well as practically negligible.

To summarize, the Silver 1 Lodide used in fabricated weather modification will not cause injury to the setting as well as human body, so citizens do not have to bother with the harm to the environment and also body. Concerning “synthetic snowfall” and “artificial snow boost”, the Qingdao Meteorological Department likewise explained on the official Weibo: fabricated snowfall = white wolf with vacant gloves, that is what the ski resorts do. There is no synthetic snowfall in the meteorological department, just snow rise procedures are performed on the basis of natural snowfall, snow increase! To place it candidly, it is to ask God for a little bit more snow.

As a matter of fact, the international neighborhood began to examine the effect of Silver 1 Lodide drivers on the environment as very early as the 1960s. The long-lasting detection results of silver ion focus after silver iodide catalyzed rainfall in the USA, Spain, Australia and also various other nations reveal that the focus of silver ions created by climate adjustment procedures is low, and the influence on the environment is much lower than the Globe Health and wellness Company requirement. my country has actually always affixed fantastic significance to the effect of fabricated weather on the atmosphere. The results of numerous examinations and also analyses show that the Silver 1 Lodide driver has no adverse result on the ecological environment.
