Ozone Layer

Ozone Layer is getting damaged by the iodine present in desert dust

The iodine present in desert dust destroys the ozone layer. Scientists have revealed this in a new study. The study has been published in the ‘Science Advances Journal‘. The amount of iodine and dust particles in the atmosphere over the Ataca of Chile and the Sechura desert of Peru is very high.

University of Colorado Boulder chemistry professor Rainer Volkmar said that this is the same iodine we use as a nutrient. He explained that when winds lift fine desert dust into the atmosphere, the iodine in that dust undergoes chemical reactions that destroy air pollution. But these allow greenhouse gases to remain the same for a more extended period.

This greenhouse gas destroys the ozone layer. Professor Rainer Volkma said that we thought that iodine was beneficial until now, but it is harmful in this case. The study of the effects of iodine on the atmosphere and ozone is currently incomplete. But it has been revealed early that it is harming ozone.

A new type of polluting element

Lead researcher of the study and scientist Theodor König at Peking University in China said that iodine reaching the ozone layer and dust particles is harmful. This is a new type of polluting element, which destroys the protective umbrella over our heads. This has also been confirmed by the Tropical Ocean Troposphere Exchange of Reactive Halogens and Oxygenated Hydrocarbons (TORERO) experiment.


Volkmar has appealed to scientists worldwide that our understanding of the sources on Earth and their chemical processes is refined, but what effect they have in the atmosphere should be studied. At the same time, most people used to think that dusty air flows below the pollution zone, but it is not so. Now the dusty air is reaching higher in the atmosphere. This is affecting the ozone.

Ultraviolet rays will wreak havoc

Volkmar said that if a large amount of iodine in the atmosphere reaches the upper atmosphere, then methane and other greenhouse gases will have a chance to stick there for life, which will destroy the ozone layer. He said that if the ozone layer ends, it is difficult to estimate how much destruction the sun’s ultraviolet rays will cause on the Earth.

What is the ozone layer?
The ozone layer is a layer of ozone molecules found in the atmosphere between 20 and 40 km. It works to protect the Earth from the sun’s harmful ultraviolet rays. If ultraviolet rays reach the Earth directly, it can be hazardous for humans, plants, and animals. In such a situation, protecting the ozone layer is very important.
