The ozone layer its characteristics role and the danger of its destruction

The Cl-catalyzed ozone depletion can take place in the gas phase, but it is dramatically enhanced in the presence of polar stratospheric clouds PSCs.

Ozone Layer Depletion – Causes, Effects and Solutions

Ozone chemicals can cause difficulty in breathing, chest pain, throat irritation, and hamper lung functioning. The limited scientific knowledge of the public led to a confusion with global warming [29] or the perception of global warming as a subset of the "ozone hole".

It adversely affects the planktons which plays a vital role in the food chain and oceanic carbon cycle. Then, the ozone-rich air is carried to higher latitudes and drops into lower layers of the atmosphere. Impact on Humans Skin cancer: Eventually they were used in a variety of products including air conditioners, spray cans, fire extinguishers, and in manufacturing foams.

The reasons for these variations are due to atmospheric circulation patterns and solar intensity. It is calculated that a CFC molecule takes an average of about five to seven years to go from the ground level up to the upper atmosphere, and it can stay there for about a century, destroying up to one hundred thousand ozone molecules during that time.

The most prominent decrease in ozone has been in the lower stratosphere. Unsourced material may be challenged and removed. Given the longevity of CFC molecules, recovery times are measured in decades.

Ozone depletion

DuPont may have feared court action related to increased skin cancer, especially as the EPA had published a study in claiming that an additional 40 million cases andcancer deaths were to be expected in the U.

This means that there will be limited amounts of NO2 present to quench the active chlorine, and the ozone depleting process can continue for several weeks. In addition, increased surface UV leads to increased tropospheric ozone, which is a health risk to humans.

Marine phytoplankton play a fundamental role in both the food chain as well as the oceanic carbon cycle. This timeline highlights milestones related to the history of ozone depletion. Reactions that take place on polar stratospheric clouds PSCs play an important role in enhancing ozone depletion.

More complicated mechanisms have also been discovered that lead to ozone destruction in the lower stratosphere. Pinotubo in the Philippines.

Ultraviolet rays can influence the survival rates of these microscopic organisms, by affecting their orientation and mobility. The ozone molecules, in turn absorb ultraviolet rays between to nm nanometers wavelength, and thereby prevent these harmful radiations from entering the Earth's atmosphere.

These conditions have led to ozone hole formation in Antarctica.

Ozone Layer Depletion – Causes, Effects and Solutions

Halogen source gases do not react directly with ozone. The ozone molecule is unstable although, in the stratosphere, long-lived and when ultraviolet light hits ozone it splits into a molecule of O2 and an individual atom of oxygen, a continuing process called the ozone-oxygen cycle.

This also keeps on changing as per the time seasonally or even daily. In such conditions the ice crystals of the cloud provide a suitable surface for conversion of unreactive chlorine compounds into reactive chlorine compounds, which can deplete ozone easily. More and more of such international agreements between countries is necessary to bring down ozone layer depletion.

What can we do about it? Ozone layer depletion first captured the attention of the whole world in the latter half ofand since then, a lot of research has been done to find its possible effects and causes.Ozone layer: Ozone layer, region of the upper atmosphere, between roughly 15 and 35 km (9 and 22 miles) above Earth’s surface, containing relatively high concentrations of ozone molecules.

Approximately 90 percent of the atmosphere’s ozone occurs from 10–18 km (6–11 miles) to about 50 km (about 30 miles) above Earth’s surface.

Ozone layer

Ozone layer, also called ozonosphere, region of the upper atmosphere, between roughly 15 and 35 km (9 and 22 miles) above Earth’s surface, containing relatively high concentrations of ozone molecules (O 3). Approximately 90 percent of the atmosphere’s ozone occurs in the stratosphere, the region.

The Ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation.

It contains high concentrations of ozone (O 3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth's atmosphere.

Ozone layer

Ozone layer depletion first captured the attention of the whole world in the latter half ofand since then, a lot of research has been done to find its possible effects and causes. Various studies have been undertaken to find out possible solutions.

What is ozone? Ozone is a gas made up of molecules that are formed by three oxygen ltgov2018.com molecule formula is O ltgov2018.com is formed when the sunlight hits oxygen molecules (O 2) and breaks them up into individual ltgov2018.com individual atoms then join up with O 2 molecules and make O 3, or ozone.
