Depletion of the Ozone Layer - Chemistry LibreTexts

Although quantitative estimates of the implications of this new finding havenot been carried out yet, impacts are likely for predicted geographical andseasonal distributions of gases such as methane (CH4) and carbon monoxide (CO),and the sensitivity of tropospheric chemistry to stratospheric ozonedepletion.Further evidence for the linkage between stratospheric UV transmission andtropospheric composition was found in the records of surface CH4 and COconcentrations.

However, these precautions will become more important as ozone depletion worsens. .

Reduction of the rainforests, continued growth in hydrocarbon industries, increases in livestock, and depletion of the ozone are all considered factors in the debate.

The threat of ozone depletion ..

Häder, Effects of stratospheric ozonedepletion on marine organisms,  16, 261-263,1989.

Chlorofluorocarbons take time to reach the ozone layer, but when they do they are broken up buy the high energy radiation from the Sun, and the halogens from the compounds are released and catalyze the destruction of ozone layer.
Effects Of Ozone Depletion
Rising Sea Levels
Ozone layer depletion is not only very dangerous because of the skin cancer and other diseases that can be caused by very strong types of radiations, but also the Ozone layer depletion is very dangerous since it could mean extreme rising sea levels which can put certain parts of the world, more specifically parts where the land is very close to sea level, in grave danger.

Once released into the environment most of the 1,1,1-trichloroethane enters the air, where it lasts for about 6 years, then once in the air, the 1,1,1-trichloroethane it can travel to the ozone layer where sunlight breaks it down into chemicals that reduce the ozone layer
Chlorofluorocarbons (CFC's) are the most widely used Ozone-Depleting Substances (ODS), and responsible for over 80% of total stratospheric ozone depletion.

Increased greenhouse gases, sulfate and dust aerosols and increased UV-B fromozone depletion are all occurring simultaneously.

Also it would be effective because the ozone layer is damaged a lot by the amount of carbon dioxide (CO2) which is released in the air by man made products, but trees through photosynthesis turn (CO2) into oxygen, and if more and more people begin to plant trees, more (CO2) that is being released will be converted into oxygen.

Ozone Friendly Products
Many people while buying products pay attention to the look, the price and the appeal of the product they are buying, but they do not look to see if the product they are buying is even eco friendly or what chemicals were used for their product.

23/03/2015 · The impact of ozone depletion

Increased ozone levels may already have decreasedphytoplankton yields in the Antarctic ocean (). Plant responses to ultravioletradiation include reduced leaf size, stunted growth, poor seedquality, and increased susceptibility to weeds, disease, andpests. Of some 200 plant species studied, two thirds showsensitivity to ozone damage (). A25% O3 depletion is expected to reduce yields of soybean, one ofcivilization's staple crops, 20% ().Red Hard disease infection rates in wheat increased from 9% to20% when experimental ozone loss increased from 8% to 16% aboveambient levels (). Clearly, thepotential exists for a significant decrease in crop yields in theperiod to 2050 from enhanced surface ultraviolet levels.

What are the causes and effects of ozone depletion?

These alterations indicatepossible consequences with regard to climate and climate prediction, becauseDMS is an important source of cloud condensation nuclei over parts of theocean.The photo-dissociation of ozone by atmospheric UV-B radiation is a key reactionthat controls urban and regional oxidants, the self-cleaning capacity of thetroposphere, and the atmospheric lifetimes of many natural and anthropogenicgases.

Human health and ecological consequences of ozone depletion.

Recent work on UV-B effects has concentrated on inhibition mechanisms and field studies in the subpolar waters of Antarctica, because of its high productivity and the occurrence of the ozone hole over this region.
Phytoplankton organisms orient within the water column using external factors.

Human health and ecological consequences of ozone depletion

These types of data,referred to here as activation spectra, are useful in the estimation of damageto polymers exposed to UV-enhancedsolar radiation that results from ozone depletion.Recent findings have shown that while solar radiation is principallyresponsible for outdoor degradation of polymers including polyethylene, factorssuch as temperature and exposure to moisture also have an impact on the usefullifetime of materials outdoors.


Forests, for example, which represent the culmination of ecological successional processes, are being destroyed at an alarming rate, due to commercial logging and clearance by impoverished peoples for agriculture and firewood. The effects of forest depletion include soil erosion, which, if extreme, can lead to desertification. Loss of biodiversity is an important consequence (see “Species extinction, biodiversity loss and human health” in this chapter). It is estimated that one-third of all carbon dioxide emissions are from the burning of tropical forests (the importance of carbon dioxide in creating global warming is discussed in “Global climate change and ozone depletion” in this chapter). Thus, addressing poverty is imperative with respect to global environmental health as well as individual, community and regional well-being.
