    30 years ago in May 1985, the first ozone hole was discovered over Antartica. This massive “hole” in the ozone layer triggered panic leading to the signing of the Vienna Convention and the Montreal Protocol. Since 1994, 16th September has been celebrated as World Ozone Day to mark the date this deal was signed.

As per a report, India, China and South Korea were responsible for 70 per cent of CFC production though the use CFCs has been banned completely in the world.

    The Arctic region, around the North Pole, is an important indicator of the impacts of industrial and human activities, both at the surface level and in the atmosphere. The rapid warming of the region has attracted considerable scientific attention. Besides the well known phenomenon of global warming occurring in our lower atmosphere, another atmospheric phenomenon had been taking place over the Arctic. Recent record low ozone values in the stratosphere have led scientists to take a closer look at the links between the changing climate and ozone distribution; changes that may undermine the recovery of the Ozone layer predicted to occur in a few decades. This 17 min. documentary was produced by the United Nations Environmental Program.

HISTORY OF OZONE DAY. Every year on September 16, the World celebrates the International day for the preservation of Ozone layer as the World Ozone Day. During the United Nations convention in Vienna for the Montreal Protocol in 1987, the General Assembly declared September 16 as the World Ozone day in order to remind the world of the depleting ozone layer. After the Montreal Protocol signing, over 190 countries acted on the use of chlorofluorocarbon CFC and banned the compound. As per a report, India, China and South Korea were responsible for 70 per cent of CFC production though the use CFCs has been banned completely in the world. World Ozone Day has been celebrated since 1994 What is ozone. The Ozone Layer is a vital component in the history of life on earth. Ozone itself is a type of oxygen but unlike the oxygen that we need to breathe, it is a poisonous gas. So, although ozone in the stratosphere is good and performs a vital function, ozone at ground level is bad. Ozone is first thought to have been identified in 1839 by Christian Schonbein, a Swiss chemist who was actually looking at electrical discharges. He named it ozone, from the Greek term “to smell”, because of its strong odour. Schonbein wasn’t able to describe the molecular structure of ozone but this was achieved by Jean-Luis Soret in the 1860s. However, Schonbein continued his research and was one of the first people to suggest that higher concentrations of ozone at ground level could affect people’s health. As history has shown, he was correct in his assumption – ozone is now known to be a main ingredient of today’s city smog. About 40 years after Schonbein’s naming of ozone, researchers examining the amount of UV radiation that reaches Earth discovered a sharp cut off point in the atmosphere – and correctly deduced that this cut off was because of ozone in the upper atmosphere. However, French scientists Charles Farby and Henri Buisson are credited with actual discovery of the Ozone Layer in 1913. They carried out the first measurements of ozone in Europe and in 1920, GMB Dobson, a lecturer in meteorology at Oxford University decided to follow their example. In the 1930s, British physicist, Sidney Chapman, produced a theory explaining how ozone is created and destroyed in the stratosphere and this process became known as Chapman Reactions. He established that when oxygen molecules in the stratosphere are hit by radiation from the sun, they can split into two oxygen atoms. When one of these separated atoms becomes attached to a complete oxygen molecule, it becomes ozone O3 . What causes this ozone depletion? Scientists have reached consensus that ozone depletion in the stratosphere is caused by ozone depleting chemicals. These chemicals contain chlorine or bromine atom with inherent chemical stability and have long lifetime in the atmosphere, in the range of 40 to 150 years. These chemicals and other trace gases drift up into the stratosphere and become involved in chlorine-releasing reactions. The chlorine atoms then react with the ozone molecules in the presence of sunlight and destroy the ozone molecules. Just one chlorofluorocarbon molecule can destroy tens of thousands of ozone molecules. How can we help to protect the ozone layer? While the vast majority of ODS usage is either industrial or commercial, individuals can help in the following ways: Buy air-conditioning and refrigeration equipment that do not use HCFCs as refrigerant. Buy aerosol products that do not use HCFCs or CFCs as propellants. Conduct regular inspection and maintenance of air-conditioning and refrigeration appliances to prevent and minimize refrigerant leakage. For existing air-conditioning and refrigeration appliances that operate on HCFCs or CFCs, the refrigerant should be recovered or recycled whenever an overhaul of equipment is to be carried out. Replacing or retrofitting such equipment to operate on non-HCFCs refrigerant should also be considered. When motor vehicle air-conditioners need servicing, make sure that the refrigerants are properly recovered and recycled instead of being vented to the atmosphere.
