A number of commonly used chemicals have been found to be extremely damaging to the ozone layer. Halocarbons are chemicals in which one or more carbon atoms are linked to one or more halogen atoms (fluorine, chlorine, bromine or iodine). Halocarbons containing bromine usually have much higher ozone-depleting potential (ODP) than those containing chlorine.

The man-made chemicals that have provided most of the chlorine and bromine for ozone depletion are methyl bromide, methyl chloroform, carbon tetrachloride and families of chemicals known as halons, chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs).

In 1994, the United Nations General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer
(resolution 49/114).

“University campuses in Parks” In celebration of the World Ozone Day 2021

Ever since its start of classes at the Hua Mak Campus the Assumption University of Thailand (AU) has taken steps to preserve the environment and to promote ozone consciousness. The lake on the Hua Mak Campus has for long been considered as the lungs of the university in that the water, trees and the water fountain recycles air, shutting out pollution and creating a refreshing feeling for faculty, staff and students.

The launch of the picturesque and green Suvaranbhumi Campus in 1999 extended the efforts and impetus of the University to uphold environmental preservation. Thus, the idea of the ozone-friendly university becomes a prominent concept of the campus wherein trees are grown, to bring nature back to young men and women so that they will be able to walk and to sit in the great silence of the landscape, with tranquility of mind, contemplating how, in peaceful splendor, the sun rises and sets while radiating warmth that gives life to all things.

In this environment, the inquisitive and inquiring minds will have their play and their fulfillment. All learners will steadily grow in knowledge and wisdom. This year the University community is encouraged to take some actions to preserve the environment and protect the ozone layers which are increasingly becoming imperiled impacting on global climate change and influencing diseases such as the ongoing COVID 19 pandemic.
