Ozone Layer

The ozone is important to human life very much. It is the gas which is there in all situations to protect us. However due to efforts of man, it is being depleted.

The ozone is a vital part for supporting life on earth. Without this ozone, harmful radiations from sun would have entered earth and would have caused a number of diseases like skin cancer and eye cataract.

No, ozone is not considered a truly renewable resource because it cannot be sustainably produced at the same rate it is consumed. Ozone is constantly being created and destroyed in the atmosphere through natural processes, but human activities can deplete ozone faster than it can be naturally replenished.

It causes harmful activities like skin cancer, cataracts. Mainly children are worst affected. It is also harmful for eyes.

CFCs, and are known ozone depleters. See the link below for what their effects are.: * Refrigerant R-10 is CCl4. * Refrigerant R-11 is CCl3F. * Refrigerant R-12 is CCl2F2. * Refrigerant R-13 is CClF3. HCFCs, and are known ozone depleters but with lowered suvivability to reach the ozone layer. See the link below for what its effects are. * Refrigerant R-22 is HCClF2. * Refrigerant R-40 is CH3Cl. It is responsible for ~17% of chlorine-assisted ozone destruction in the statosphere. It is today primarily produced by plants, and the combustion of organic waste materials, since its use in industry was stopped some time ago. CFCs inclusive of HCFCs, are ~82% of the chlorine currently found in the stratosphere Some refrigerants that do not contain chlorine or bromine are: R-14, R-23, R-32, R-41, R-50, R-116, R-125, R-E125, R-134, R-134a, R-E134, R-143, R-143a, R-143m, R-E143a, R-152, R-152a, R-161, R-170, R-218, R-227ca, R-227ca2, R-227ea, R-227me, R-236cb, R-236ea, R-236fa, R-236me, R-FE-36, R-245ca, R-245cb, R-245ea, R-245eb, R-245fa, R-245mc, R-245mf, R-245qc, R-254cb, R-254pc, R-263, R-272, R-281, R-290, R-C318, R-3-1-10, R-347mcc, R-347mmy, R-365mfc, a few of the blends between R-400 and R-600, R-600, R-600a, R-601, R-601a, R-610, R-611, R-630, R-631, R-702, R-704, R-717, R-718, R-720, R-728, R-732, R-740, R-744, R-744A, R-764, R-784, R-1114, R-1132, R-1141, R-1150, R-1216, R-1270 This list includes chemicals that are so stable that they also can accumulate over decades as CFCs did, and yet new problems may result from their use and/or release into the environment. Others of them are fuels (so are flammable), components of natural gas, and may not accumulate, but can contribute to ozone pollution as a VOC.

Ozone can destroy air pollutants such as carbon monoxide, volatile organic compounds, and other harmful chemicals by breaking them down into harmless substances through a process called oxidation. However, ozone can also be harmful to human health when present in high concentrations, causing respiratory issues and other health problems.

Ozone depletion leads to increased UV radiation reaching the Earth's surface, which can cause skin cancer, cataracts, and harm to marine life and ecosystems. It can also impact crop yields and disrupt food chains.

The ozone layer protects people from the harmful ultraviolet radiations of the sun. These radiations are of very high frequency and thus can cause some very serious problems among living organisms.

Ozone layer has many holes in it. However it has a considerable major hole in it above Antartica continent. It is formed due to CFC gas. Beacuse of the hole there is an increase in the temperature of earth.

UV waves are important in the world because lots of creatures like bees use it to navigate and survive.

:D

Some do. Mostly they are the supersonic long distant flyers that have a long ways to go.

Otherwise there is little reason to waste all that fuel to go so high.

The ozone layer (in the stratosphere).

Certain CFCs have been banned, which turned out to be long-term ozone depleters. Other than that, increasing gas prices (caused by speculators trying for profit), will be the next big step by reducing combustion of fossil fuels (slight increase in oxygen, slight decrease in water vapor at altitude).

Ozone (O3) is an allotrope of oxygen, so obviously there can be no ozone if there is no oxygen somewhere. There is negiligible amounts of oxygen on Mars, yet there is a detectable amount of ozone there. Carbon dioxide may actually be supplying some of the oxygen required to form it...

Ozone gas makes one important part of the atmosphere. It protects us from the deadly UV rays.

are released by air conditioners into the ground water.

Depletion of the ozone layer can result in increased levels of harmful ultraviolet (UV) radiation reaching Earth's surface, leading to a higher incidence of skin cancer, cataracts, and weakened immune systems in humans. It can also disrupt ecosystems by damaging phytoplankton and disrupting food chains in aquatic environments. Furthermore, ozone depletion can have detrimental effects on agriculture by reducing crop yields and affecting plant growth.

CFC's were banned because in the upper atmosphere they can decompose ozone under the impact of ultraviolet radiation (which is stronger there) to form free radicals, which then catalyze the decomposition of ozone. Because they act as catalysts, they are not used up in the reaction and can continue to decompose many, many ozone molecules per molecule of CFC.

The ozone layer is the main barrier to ultraviolet light, so weakening it would mean more UV reaching the surface. UV light is deadly to one-celled organisms, and it's not all that great for higher animals either, since it can cause skin cancers.

As a "shield", it prevents certain wavelengths of UV from passing. As an occasional event (lightning), it destroys odorous compounds. With chronic (long term) exposure. it damages / destroys plants ability to respire, and animal's lung tissue. Ozone is used by marigolds to fight root parisitism, and by white blood cells to fight infection. In aquaria, ozone plays an important part in purification of water (reactivation of natural bromine), with similar damage to fish's gill structures under high ozone concentrations or long term exposure.

CFC are photoactivated to a state that will aid in destruction of ozone, release the oxygen atom later, and reset to do it all over again. http://books.google.com/books?id=Ttwh4HtVFngC&pg=PA136&lpg=PA136&dq=CFCs+ozone+photocatalytic+-ti02&source=web&ots=ZSrwSRgbTo&sig=bhDV6pTQ4DYwAY-qD2jY8wjbJ_0&hl=en&sa=X&oi=book_result&resnum=6&ct=result

You can find ozone in any layer of the atmosphere, but in the lower layers it does not last long. The so-called ozone layer is in the lower portion of the stratosphere, at a height where it takes a long time to dissociate.

UV-B passes to Earth's surface, when ozone does not stop it. UV-B can travel some short distance into seawater before it is scattered and its energy reduced. Phytoplankton has DNA, and lives near the surface of the ocean where sunlight is strong. UV-B destroys DNA.

So ozone depletion kills or mutates phytoplankton, via UV-B from the Sun.

The ozone layer is present in the stratosphere region of the atmosphere. It is important as it protects us from the harmful UV radiations of the sun that cause several health hazards including skin cancer!

There is a gradula thinning of the ozone in the atmosphere because of the ozone depleting substances. These substances contain CFC's which deplete the ozone by reacting with it.

There are no parts to the ozone layer. Ozone is found in all layers of the atmosphere, with near zero concentrations at very high altitudes and near the Earth's surface. The lower portion of the stratosphere reaches peak ozone concentration (9-10 ppm), and this is usually referred to as the ozone layer. In the winter at one of Earth's poles, an ozone hole forms. The size of the is a function of contaminants that may be found at those altitudes that accelerate the otherwise natural decay of ozone.

The amount of ultraviolet radiation we are exposed to on Earth increases because the ozone layer, which was supposed to form a barrier to protect us from the UV rays, have decreased in amount. UV rays are bad for health; skin cancer and the weakening of our immune systems.
