In appropriate contexts, ozone can be viewed as trioxidane with two hydrogen atoms removed, and as such, trioxidanylidene may be used as a context-specific systematic name, according to substitutive nomenclature. By default, these names pay no regard to the radicality of the ozone molecule. In even more specific context, this can also name the non-radical singlet ground state, whereas the diradical state is named trioxidanediyl. Trioxidanediyl or ozonide is used, non-systematically, to refer to the substituent group -OOO-.
Care should be taken to avoid confusing the name of the group for the context-specific name for ozone given above.
Beaumont , California had as its official slogan "Beaumont: Zone of Ozone", as evidenced on postcards and Chamber of Commerce letterhead. Scientists, however, noted its harmful effects.
In James Dewar and John Gray McKendrick documented that frogs grew sluggish, birds gasped for breath, and rabbits' blood showed decreased levels of oxygen after exposure to "ozonized air", which "exercised a destructive action".
The gas was applied directly to wounds for as long as 15 minutes. This resulted in damage to both bacterial cells and human tissue. Other sanitizing techniques, such as irrigation with antiseptics , were found preferable.
It is dangerous to allow this liquid to warm to its boiling point, because both concentrated gaseous ozone and liquid ozone can detonate.
Exposure of 0. Exposure to higher amounts of UV radiation could have serious impacts on human beings, animals and plants. What does this mean for life on earth? Even the smallest reduction in stratospheric ozone can have a noticeable impact by increasing the amount of UV radiation that reaches the planet.
If this ozone becomes depleted, then more UV rays will reach the earth. It can bring harm to human health through the form of skin cancers, sunburns and premature aging of the skin; cataracts, blindness and other eye diseases because UV radiation can damage several parts of the eye, including the lens, cornea, retina and conjunctiva; and weakening of the human immune system immunosuppression.
UV radiation can also have an adverse impacts on agriculture, forestry, natural ecosystems and on raw materials like wood, plastic, rubber, fabrics and many construction materials that can have an economic impact to the world and can badly damage the marine life yielding to the loss of biodiversity in our oceans, rivers and lakes could reduce fish yields for commercial and sport fisheries.
Under the Montreal Protocol, the federal government is responsible for controlling the import, manufacture, use, sale and export of ODS. The government must pass the Ozone Depleting Substances Regulation to control ODS stored in products and equipment, and encourage consumers and industry to use more environmentally safe alternatives. In the implementation of the regulation, there are classes made to categorize different ODS.
Class I lists all CFCs and halons, as well as methyl chloroform and carbon tetrachloride. Class I substances are considered to have the most significant impact on ozone layer depletion.
Ozone depletion became a global issue when it became a unrelenting concern for everyone when it suddenly became a threat to survival of mankind.
We may not see it in our naked eye but we can feel it effects.
Temperatures are fluctuating. Droughts, typhoons and floods are keep on happening. Sea levels are said to be rising. Why is it happening? Most of us will pin point at the occurrence of Global Warming as a result of ozone depletion. Nowadays, this two words are becoming common and almost everyone heard a lot about it and yet, it seem that other people still need more convincing.
This global issue has been one of the most prioritized agenda of various number of environmentalists, climate scientists, and governments worldwide in their conferences and meetings. Despite the growing evidence indicating that our world may be in danger, there are still some people and interest groups that claims that global warming is a hoax and it is just a conditioning.
Since then, ozone depletion had brought global warming, it is put under trial and has become a case of where a lot of arguments are being presented in the hearing. Even there is now a scientific consensus about this matter, some people still don't think that global warming is happening.
So, whether we understand it or not, the concern people showed and proposed evidences supporting that what is happening is real and is continuously arising.
Different environmental protocols and policies are being planned, implemented and evaluated to save Earth. The government of each country help prevent further Ozone Depletion through laws and by attending world conferences like UN.
Every nation of the world have taken a crucial step in joining together to halt the production and use of ozone-destroying chemicals. But how ordinary people like us can help in restoring the ozone layer.
So, here are some ways in which we can contribute to protecting the ozone layer and our precious Earth. First and the most common of all is by being aware of what is happening around us and by educating oneself of the background and the said global issue.
Second, the limit use of private vehicles is very much appreciated. A very easy way to control ozone depletion would be to limit or reduce the amount of driving as vehicular emissions eventually result in smog which is a culprit in the deterioration of the ozone layer.
Carpooling, taking public transport, walking, using a bicycle would limit the usage of individual transportation. Third, the usage of eco-friendly and natural cleaning products for household chores is a great way to prevent ozone depletion. This is because we all know that many of these cleaning agents contain ODS and other toxic chemicals that interfere with the ozone layer. A lot of supermarkets and health stores sell cleaning products that are toxic-free and made out of natural ingredients.
If we have gardens at home, we may use pesticides to protect our plants but these are harmful for the ozone layer. The best solution for this would be to try using natural remedies, rather than heading out for pesticides.
You can perhaps try to weed manually or mow your garden consistently so as to avoid weed-growth. Everyone not only those in higher administration must put in mind the effect of too much abuse to the natural resources and must encourage to be involve in the recovery of ozone hole that may yield to less UV radiation that will actually result to less global warming and will now contribute to the increase of biodiversity and control in the causes of pollution.
Overall, the world must remember that sustainability can only be achieved through increased international cooperation to conserve resources, lessen the use of harmful substances like ODS and protect our vulnerable habitat, Earth.
It may be through simple things but for sure it can make a big difference. It must also tap how leaders should steer away from misguided decisions to be able to guide the community in viewing the past experiences mankind had gone through especially the negative ones as a constant reminder and a tool to help us to decide which options offered by science and technology are right and for the common good to address not only the waste disposal problems but also the bigger environmental and societal problems like ozone depletion that may arise.
