The main causes of the depletion of the ozone layer in the atmosphere

However, their application is greatly restricted since they are utilized in specific fire extinguishers. Thus, unlike environmental agreements of the past, the treaty was not a response to harmful developments or events, but rather a preventive action on a global scale".

The initial progress motivated Leonard to comply fully with the program. Ozone layer normally develops when a few kinds of electrical discharge or radiation splits the 2 atoms in an oxygen O2 molecule, which then independently reunite with other types of molecules to form ozone.

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, Sun, Cancer, edited by L. Above the boundary layer, but within the troposphere, the primary standard observation platform is the radiosonde.

Ozone Layer Protection

Figure 1 compares measurements done at the Dombaas research center in two periods: Deposition nuclei are analogous to condensation nuclei in that water vapour directly deposits as ice crystals on the aerosol. Cuba's Ozone Research Center, at Havana's National Center for Scientific Research, recently investigated the cholesterol- lowering effect of the substance.

If drug companies have an influence on medical schools and medical research, then this information will never get there. Total column ozone declined below pre values between and for mid-latitudes. In essence, they absorb the molecule's altered energy state and return it to a normal state without hamming the system.

Causes and Effects of Ozone Layer Depletion That are Painfully True

Ozone Induces Specific Enzymes The formation of short-lived peroxides at the membrane are injected into the cell and are removed by the enzyme glutathione peroxidase. Chelation therapy is primarily for opening up capillaries and increasing the ability of the oxygen and ozone to permeate the tissues.

Air containing water vapour with a relative humidity greater than percent, with respect to a flat surface, is referred to as being supersaturated. The Chelation would help improve Quentin's blood circulation by removing heavy metals and arterial plaque.

The development of clouds in such a fashion, which occurs only in a controlled laboratory environmentis referred to as homogeneous nucleation. Grossman, it took this long to complete the Crista experiment largely because funding for this kind of reseaeh is limited.

Biological effects[ edit ] The main public concern regarding the ozone hole has been the effects of increased surface UV radiation on human health. Upwelling creates areas of cold coastal surface waters that stabilize the lower troposphere and reduce the chances for convection.

Over a three-month period, this wound failed to heal even with antibiotics and Leonard's doctors were talking about amputating his foot. The key observation is that, ordinarily, most of the chlorine in the stratosphere resides in "reservoir" compounds, primarily chlorine nitrate ClONO 2 as well as stable end products such as HCl.

Health and Environmental Effects of Ozone Layer Depletion

However, fluorine atoms react rapidly with water and methane to form strongly bound HF in the Earth's stratosphere, while organic molecules containing iodine react so rapidly in the lower atmosphere that they do not reach the stratosphere in significant quantities. Both the F1 and F2 regions possess high ion density and are strongly influenced by both solar activity and time of day.

Oxygen, ozone, and substantial quantities of various nutrients, including beta carotene, vitamins C, E, B6, zinc, selenium, glutathione, pygnogenol, and quercetin, help the body to better utilize oxygen.

To become a growth medium for such parasites, one has to have allowed the oxygen saturation of the bodies fluids to drop well below the optimum level for healthy cell growth and function.

The Van Allen radiation belts contained within Earth's magnetosphere.

Ultraviolet radiation and health

Such fronts are defined as active fronts. A correct statistical analysis showed that the trend in UV was zero that is to say, the amount of UV had neither increased nor decreased over the five-year period. Precipitation Liquid droplets The evolution of clouds that follows the formation of liquid cloud droplets or ice crystals depends on which phase of water occurs.

The ITCZ corresponds to the equatorial trough and is the mechanism that helps generate the deep cumulonimbus clouds through convection. Bromine atom is believed to be 40 times more destructive than chlorine molecules.

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.

The data suggest that substantial natural sources exist for atmospheric methyl bromide CH 3Br. Since motion upward is constrained by the stratosphere, the slowly cooling air must descend.A newly released study, produced with help from eight universities, found some good news.

Between andthe global impact of human activities on the terrestrial environment is expanding more slowly than the rates of economic and/or population growth. Climate Ozone Depletion Today, there is widespread concern that the ozone layer is deteriorating due to the release of pollution containing the chemicals chlorine and bromine.

Such deterioration allows large amounts of ultraviolet B rays to reach Earth, which can cause skin cancer and cataracts in humans and harm animals as well. Stratosphere and mesosphere. The stratosphere is located above the troposphere and extends up to about 50 km (30 miles). Above the tropopause and the isothermal layer in the lower stratosphere, temperature increases with height.

Temperatures as high as 0 °C (32 °F) are observed near the top of the stratosphere. The stratospheric ozone layer is Earth’s “sunscreen” – protecting living things from too much ultraviolet radiation from the sun.

Ozone depletion

The emission of ozone depleting substances has been damaging the ozone layer. The Ozone Depletion Theory. The theory that man-made CFCs would deplete the ozone layer is one of many theories claiming that ozone depletion would lead to doomsday.
