Ozone layer depletion is the thinning of the ozone layer present in the upper atmosphere. This happens when the chlorine and bromine atoms in the atmosphere come in contact with ozone and destroy the ozone molecules. One chlorine can destroy 100,000 molecules of ozone. It is destroyed more qui...
In subject area: Earth and Planetary Sciences Ozone Depletion Potential refers to the estimated impact of a substance on the depletion of the ozone layer, measured in terms of its equivalence to CFC-11 emissions. It helps in evaluating the potential ozone layer damage caused by greenhouse gas em...
Global Warming and Ozone Layer Depletion: STS Issues for Social Studies Classrooms The Montreal Protocol has banned methyl bromide, a pesticide widely used to fumigate wheat and numerous other agricultural products, from use after the year 2001 because of its role in ozone layer depletion. Interestin...

Liam and Lim reported the results of a survey study to assess the awareness of the ozone layer and its depletion by CFCs in MDIs among 113 consecutive asthmatic patients aged 12 years and older (Liam and Lim 1998). The investigators reported the following results (Liam and Lim 1998). (1...
All of us are aware of how the concern related to depletion of ozone layer and the ozone hole, which also led to the ban of many chemicals such as the chlorofluorocarbon (CFC). Depletion of O3 can increase UV radiation entering Earth surface. This threat

Maybe not. The protective atmospheric layer of ozone around our planet has been thinning over Antarctica for many years. New satellite data indicates the 2008 ozone hole is larger both in size and ozone loss than 2007 but is not as large as the record year of 2006. This year the area of...
and decomposes to oxygen on warming. It is present in the upper layers of the atmosphere, where it screens the Earth from harmful short-wave ultraviolet radiation. There is concern that the ozone layer is possibly being depleted by the use of fluorocarbons and other compounds produced by ...
The framers of the protocol also broke new ground in another way; they realized their agreement might not suffice if future scientific work revealed that the ozone layer faced even greater danger. Uppermost in their minds was concern over the Antarctic ozone hole and its possible implications for...
