This paper will explore what exactly ozone depletion is. It will talk about the definition of ozone depletion and what some of the things are that causes it. This paper will connect global warming with ozone depletion. This paper will give you examples of both biological and environmental. The main thing this paper will talk about is verification that the ozone layer is getting smaller. It will talk about the technologies that are used to test the ozone layer and exactly how much smaller it is getting. Keywords: ozone depletion, global warming, verification, technologies The Causes:
Effects of Ozone Depletion Have you ever wondered what protects us from the Sun’s violent rays? Well that would be the ozone layer. Without the ozone layer the sun would burn many different things up on earth, including us as humans. There are lots of concerns that the ozone layer is depleting. There are certain causes for this and most of them have to do with the choices we are making her on earth. The ozone layer is a belt of naturally occurring ozone gas. The ozone layer sits 9. 3 to 18. 6 miles above Earth and serves as a shield, protecting us from the harmful ultraviolent B radiation emitted by the sun.
The ozone is a highly reactive molecule that contains three oxygen atoms. It is constantly being formed and broken down in the high atmosphere region called the stratosphere . Ozone depletion, which is what everyone is concerned about, is the destruction of the upper atmospheric layer of ozone gas, caused by substances formed from breakdown of ozone depleting substances. There are many concerns that the ozone layer is deteriorating due to the release of pollution containing the chemicals chlorine and bromine. These chemicals are called “ozone-depleting substances” (ODS).

Yes, it is the hole in the ozone layer known as the "Ozone Layer Depletion." ... rays, before it reaches the earth's surface" (greenhouse. net)." Concerns about damage to the ozone layer go back tothe early ... CFC's and other ozone-depleting substances released by human activities. The first real evidence of ozone depletion was reported in ...
ODS are very stable, nontoxic and environmentally safe in the lower atmosphere, which is how they came so popular in the first place. The bad thing is their very stability allows them to float up, intact, to the stratosphere. Chlorine and bromine destroy the ozone layer at a rapid rate. They do so by stripping an atom from the ozone molecule. One single molecule of chlorine can break apart thousands of molecules of ozone. Another chemical that mainly plays the largest roll in the deterioration of ozone is chlorofluorocarbons (CFCs).
This chemical is found mainly in spray aerosols heavily used by industrialized nations for much of the past 50 years. When CFCs reach the upper atmosphere, they get exposed to ultraviolent rays. This causes them to break down into substances that include chlorine. The chlorine reacts with the oxygen atoms in the ozone and tears apart the ozone molecule . Halons also play a role in breaking down the ozone layer. Halons are used in specialized fire extinguishers. The main problem with halons is they can destroy up to 10 times as much ozone as CFCs can. This is the main reason halons are the most serious ozone-depleting group of chemicals.
Hydrofluorocarbons (HFCs) are being developed to replace CFCs and halons. They are uses are for vehicle air conditioning. HFCs do not deplete ozone, but they are strong greenhouse gases. CFCs are even more powerful contributors to global climate change. HFCs are still a better option until a safer substitutes are discovered. Global warming is not the cause of the ozone depletion. They are connected in another way. The ultraviolent radiation from global warming represents less than once percent of the energy from the sun. That’s no enough to be the excess heat from human activities. Global warming is caused by putting too much carbon into the atmosphere when coal, gas, and oil are burned to generate electricity or to run our cars.
The Essay on Global Warming 55
Global warming is the term used to describe a gradual increase in the average temperature of the Earth’s atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. Even though it is an ongoing debate, it is proved by the scientists that the planet is warming. Global warming is affecting the nature’s balance and has a huge impact on life like continued heat ...
The gases spread through the planet like a blanket, capturing the solar heat that would otherwise float out into space . The main connection global warming and the depletion of the ozone have is human activities on earth. We release gases into the air and alter the atmosphere. The atmosphere is one connected system. Evidence suggests that climate change may contribute to thinning of the protective ozone layer. With continuous releasing of these horrible gases that we continue to use, the ozone layer will get smaller .
Ozone depletion has many biological effects on the globe. With the ozone depleting it effects the reproduction cycle of phytoplankton, single-celled organisms such as algae that make up the bottom rung of the food chain. Biologists fear that reduction in phytoplankton will lower the populations of other animals. Also studies have shown changes in the reproductive rates of young fish, shrimp, and crabs. As well as in frogs and salamanders. This is all due to them being exposed to excess ultraviolent B . There are also environmental effects from ozone depletion. The one I’m going to talk about is the effect it has water.
With the rise of UV B getting worse it effects the marine life which live in water. Basically when the UV B reflects into the water is causes small organisms to be threatened. These small organisms are called plankton. These plankton that live in the water are a vital step in the aquatic food chains. Decreases in plankton could disrupt the fresh and saltwater food chains, and lead to a species shift. The loss of biodiversity in our waters, due to UV B, could reduce yields for commercial and sport fisheries . There are many different instruments that scientists use to measure ozone depletion.
One instrument is the ozonesonde, which includes a balloon that carries the instrument up more than 21 miles high to the stratosphere. When it gets into the stratosphere it sucks in and holds air to test the amount of ozone gas using an electrochemical concentration cell (ECC).
It uses potassium iodide, which reacts with ozone to create an electrical current, to measure the amount of ozone present . Another instrument scientist’s use are instruments on satellites. These are called TOMS (Total Ozone Mapping Spectrometer).
The Research paper on Depletion Of The Ozone Layer: Its Causes, Effects, And Possible Solutions
The depletion of the ozone layer is a major concern today. The ozone layer protects us from the harmful rays of the sun; therefore it is imperative that we preserve it. Since more pollutants are produced today than ever before (because of the major increase in the population), there is a major concern that we create less pollutants to help conserve the ozone layer. In this research paper I will ...
This instrument determines the amount of ozone present in the ozone layer by reading backscattered UV light.
This is the UV light that earth emits back into space. When scientists measure the amount of total ozone, they measure the amount of ozone gas in a column of air. When measuring the ozone, they use the Dobson units . In conclusion to all the information talked about dealing with ozone depletion, we as humans are the main cause. Using less chemicals that harm the ozone is what needs to be done. If harmful UV B rays continue to get worse it can cause severe burns on humans as well as cataracts. It can also cause the animal life to go decrease and the burning up of crops to increase. We need to do our part and watch the chemicals we use.
