The document discusses the depletion of the ozone layer. It states that chlorofluorocarbons (CFCs) are one of the major causes of ozone layer depletion as they mix with other gases like carbon dioxide and nitrogen dioxide. CFCs are fully or partly halogenated hydrocarbon derivatives of methane, ethane and propane that are commonly used in refrigerators, air conditioners, and spray paints. The document notes that while CFC consumption has reduced due to international agreements like the Montreal Protocol, the 2020 lockdowns due to the COVID-19 pandemic further reduced pollution and allowed the ozone layer to begin healing itself.

Ozone Depletion Potential of Different Refrigerants
Ozone depletion occurs when CFCs and HCFCs released into the atmosphere reach the stratosphere. Ultraviolet radiation causes these compounds to break down and release chlorine atoms which then catalyze the breakdown of over 100,000 ozone molecules each. International agreements like the Montreal Protocol have led countries to phase out ozone depleting substances and strengthen protections for the ozone layer.
Ozone depletion potential of different refrigerants
The document discusses ozone depletion potential of different refrigerants and the mechanisms by which CFCs and HCFCs damage the ozone layer when they reach the stratosphere. It explains that chlorine atoms released from these refrigerants can break down over 100,000 ozone molecules each. It also provides details on common types of refrigerants like CFCs, HCFCs, HFCs and their ozone depletion potentials.
Ozone Layer Depletion- activity 15.4.pptx
Manufactured halocarbon chemicals used in products like refrigerants, foam blowing agents, and propellants are the main cause of ozone layer depletion. These ozone depleting substances include chlorofluorocarbons, carbon tetrachloride, methyl bromide, and hydrochlorofluorocarbons. An international agreement in 1987 set limits on CFC production, and reducing emissions of ozone depleting chemicals has helped decrease the size of the ozone hole over Antarctica in recent years.
Ozone layer depletion
This document discusses the ozone layer and its depletion. It begins with an introduction to the discovery of ozone layer depletion by scientists in the 1970s. It then discusses the formation and location of stratospheric and tropospheric ozone. The main causes of ozone layer depletion are chlorofluorocarbons (CFCs) and other ozone depleting substances like halons. The impacts of depletion include increased UV radiation reaching Earth's surface, harming human health, agriculture and plants. International agreements like the Montreal Protocol have sought to phase out the production and use of ozone depleting substances to protect the ozone layer.
air pollution.pptx
Air pollution is caused by both natural and human-made pollutants, including particulate matter, gases, and biological molecules. Common air pollutants are particulate matter, nitrogen oxides, sulfur dioxide, carbon monoxide, ozone, and chlorofluorocarbons. Nitrogen oxides are produced by combustion and harm the respiratory and cardiovascular systems. Carbon monoxide reduces oxygen in the blood and chlorofluorocarbons were widely used but deplete the ozone layer. Smog results from emissions reacting with sunlight and air, reducing visibility and potentially causing respiratory issues and heart/lung disease.
cfc and its protocol to reduce its usage
This document summarizes information about chlorofluorocarbons (CFCs), their effects on the ozone layer, and international protocols to reduce CFC usage. It discusses that CFCs do not occur naturally and were widely used as refrigerants and propellants until their ozone-depleting effects were discovered. The Montreal Protocol was established in 1987 to set a schedule for reducing CFC usage to protect the ozone layer. Substitutes have been found for some CFC applications, and market responses are helping exceed the reductions proposed by the Montreal Protocol.

Ozone depletion
Ozone depletion is primarily caused by chlorofluorocarbons (CFCs) which were historically used in air conditioners, refrigerators, aerosol sprays, and plastic foams. CFCs undergo chemical reactions in the atmosphere that destroy ozone molecules in the stratosphere. This has led to a large ozone hole forming over Antarctica that is enlarging and could take over 50 years to restore. The thinning ozone layer allows more ultraviolet radiation to reach the Earth's surface, increasing risks of skin cancer, cataracts, and damage to plants and marine life.
9Global warming, GH effect, Ozone depletion and Acid Deposition.pdf
This document discusses global warming and climate change. It begins by explaining how greenhouse gases like carbon dioxide and methane trap heat in the atmosphere, causing the greenhouse effect and global warming. It then discusses how the concentration of carbon dioxide has increased since the industrial revolution due to human activities like burning fossil fuels. This is causing the average global temperature to rise by about 0.5°C over the past century. General circulation models predict further warming of 1.5-4.5°C by 2100 will cause sea levels to rise and affect agriculture, ecosystems, and human health.
Cfc
Chlorofluorocarbons (CFCs) are organic compounds containing only carbon, chlorine, and fluorine. They were produced as volatile derivatives of methane, ethane, and propane. CFCs were discovered in 1928 and used as refrigerants and propellants until the 1970s when scientists discovered they were depleting the ozone layer. Regulations began banning their use in 1978. CFCs react with ozone in the stratosphere, destroying it and creating a risk to human health and ecosystems from increased UV radiation. International agreements now strictly limit CFC production and use to recover the ozone layer.
Greenhouse effect global worming
Ozone layer depletion occurs when ozone-depleting substances like CFCs break down ozone molecules in the stratosphere. This allows more ultraviolet radiation to reach the Earth's surface, increasing health and environmental risks. The ozone hole was first detected in 1975 and grew substantially in size through the 1980s and 1990s before stabilizing due to the Montreal Protocol banning CFCs. Global warming occurs when greenhouse gases like carbon dioxide trap heat in the lower atmosphere, increasing average surface and lower atmospheric temperatures globally over long periods of time. Both phenomena pose risks but international agreements have led to reductions in their drivers.
how alkanes affect ozone layer
Methane and CFCs both contribute to ozone depletion and global warming. Methane is a potent greenhouse gas that is 21 times more harmful than carbon dioxide. It reacts with chlorine in the stratosphere, protecting ozone, but also attacks ozone directly. CFCs destroy ozone by releasing chlorine atoms when exposed to UV radiation, which then break down ozone molecules. While CFCs have been phased out under the Montreal Protocol, methane emissions continue from sources such as livestock, landfills, and fossil fuel extraction. Both gases trap heat in the atmosphere and are contributing to rising global temperatures.
Llb el u 3.1 ozone.delpetion
The document discusses ozone depletion and the importance of the ozone layer. It describes how CFCs released into the atmosphere were depleting the stratospheric ozone layer. The ozone layer protects life on Earth by absorbing harmful ultraviolet radiation from the sun. CFCs were initially widely used but are now known to release chlorine atoms that destroy ozone molecules. The consequences of ozone layer depletion include increased UV radiation reaching the Earth's surface, which can harm humans through higher rates of skin cancer and cataracts, and harm ecosystems and food supplies. International agreements like the Montreal Protocol have led to bans on CFCs and their replacement with more ozone-friendly substances to help restore the ozone layer
The Ozone Depletion By Christian Dave Caylo
Ozone depletion refers to the steady decline of ozone in Earth's stratosphere since the late 1970s. The thinning of the ozone layer has allowed more ultraviolet radiation to reach the surface. Chlorofluorocarbons (CFCs) emitted from products like aerosols, refrigerants, and foam cushions are the primary cause of ozone depletion as they release chlorine atoms that destroy ozone molecules. Banning the production and use of CFCs and other ozone-depleting substances has helped limit further damage to the ozone layer.
Montreal Protocol and Ozone Layer Depletion
This presentation provides comprehensive information about Ozone, Ozone Layer, Ozone Layer Depletion, International Initiatives and Analysis of Montreal Protocol.
12 ozone depletion
The document discusses ozone depletion and its causes, effects, and solutions. It explains that CFCs released into the atmosphere destroy stratospheric ozone, leading to formation of the ozone hole. This increased UV exposure can cause skin cancer, eye disease, and harm ecosystems by reducing plankton populations. International agreements like the Montreal Protocol phased out CFCs and countries are working to restore the ozone layer.
Design of Air conditioning System
The document discusses ozone science, including what ozone is, how it is created and destroyed, the ozone layer, the ozone hole, effects of ozone depletion, causes of depletion, and ways to save the ozone layer. Specifically, it explains that ozone is a gas that protects Earth from UV rays, the ozone layer blocks most UV-B and all UV-C radiation. The largest ozone hole is found over Antarctica due to cold temperatures and chemicals like CFCs from spray cans and refrigerants. Depletion allows more UV rays to reach the surface and harm life. The document recommends consumers support alternatives to ozone depleting substances to help preserve the protective ozone layer.
Ozone Depletion and the Montreal Protocol
The document discusses the Montreal Protocol, an international agreement signed in 1987 to reduce ozone depletion. It outlines that CFCs and other chemicals were destroying the ozone layer, which protects life on Earth from UV radiation. The Protocol set limits on ozone depleting substances and has led to a decrease in their atmospheric levels and early signs of ozone layer recovery, making it one of the most successful international environmental agreements.
Summary of topic 5.6
The document discusses depletion of stratospheric ozone. It notes that an important layer of ozone is located in the stratosphere between 10-15 km above the Earth. This ozone layer absorbs much of the sun's harmful UV rays. However, certain man-made pollutants, such as chlorofluorocarbons (CFCs), were depleting the ozone layer by catalyzing the breakdown of ozone molecules. The first ozone hole was detected over Antarctica in 1985. Increased UV radiation is linked to health issues in humans, environmental damage, and reduced crop yields. International agreements like the Montreal Protocol have led to bans on ozone-depleting substances, but their effects will persist for decades.

Major effects of air pollution include respiratory illnesses and heart disease in humans as well as damage to materials and negative impacts on wildlife habitats and health.
02 ozone depletion
Ozone depletion is caused primarily by chlorofluorocarbons (CFCs) and halons released into the atmosphere. CFCs can take 20-40 years to reach the stratosphere, where ultraviolet radiation breaks them down, releasing chlorine atoms that then catalyze the destruction of ozone molecules. One chlorine atom can destroy thousands of ozone molecules. The ozone layer protects life on Earth from ultraviolet radiation, and its depletion leads to increased skin cancer and other negative health effects. The Montreal Protocol was implemented to phase out the production of CFCs and halt ozone layer depletion.

- 1. Ozone layer
- 2. Depletion of ozone layer. • One of the major reason due to which depletion of ozone occur is due to the presence of the gas named chloro f luorocarbons (CFCs) in our environment. • Which, then mixes with other gases such as (carbon- Di- oxide , nitrogen -di- oxide ,sulphur - di- oxide. Etc. )and helps them to depletion ozone layer.
- 3. • Chloro f luorocarbons and hydrochloro f luorocarbons are fully or partly halogenated para ff in hydrocarbons that contain only hydrogen ,chlorine, and f luorine , produced as volatile derivative of methane, ethane, and propane. They are also commonly known by the DuPont brand name Freon. • The means of chloro f luorocarbons are: Refrigerators , Air conditioners, spray paints etc. Chloro f luorocarbons
- 4. Status of Ozone Layer. • Present status of ozone layer is A signi f icant reduction in the consumption of ozone- depleting substances (ODS) has been achieved by the EEA-33 countries since 1986. This reduction has largely been driven by the 1987 United Nations Environment Programme (UNEP) Montreal Protocol. • But, this year due the pandemic (Corona virus) COVID 19 the lockdown was conducted because of which pollution level in environment was also dropped as a result chloro f luorocarbon gas also was unable to mix with other gasses as a result ozone layer also start healing itself. • So as if now ozone is also healed and is f it as earlier.
