Adequate amount of iodine in salt protects people from various diseases including goiter. But the same iodine found in the desert is destroying the weight layer that protects the earth.
Until now, scientists have identified chlorofluorocarbons as the cause of weight loss. But recent research has shown that iodine in desert sand dust also plays a role in depleting the ozone layer. This is increasing the size of the weight hole.
When strong winds blow desert dust into the atmosphere, the iodine in it participates in a
chemical reaction. Such chemical reactions cause greenhouse gases to remain in the
atmosphere for long periods of time and deplete the ozone layer.
According to Rainer Volcamor, a professor of chemistry at the University of Colorado, iodine, which acts as a nutrient in salt, destroys the ozone layer in the atmosphere. He says that iodine not only affects air quality but also contributes to climate change.
According to Rainer, iodine causes greenhouse gases to stay in the atmosphere longer. These greenhouse gases destroy the ozone layer. So, scientists need to think anew about ozone depletion and pollution.
Recent studies have disproved the earlier notion that airborne particles, including dust
particles, reach the very bottom of the atmosphere.
According to scientists, the ozone layer prevents the sun’s ultraviolet rays from reaching the earth. The destruction of the ozone layer will send ultraviolet rays directly onto the earth and will have a negative effect on humans as well.
