Ozone Depletion Essay

Some of the pollutants released include: toluene, benzene, xylene and ethyl benzene, ground level ozone (also known as smog), nitrogen oxides, carbon monoxide, and formaldehyde. Exposure to these pollutants are known to cause short-term illness, organ damage, nervous system disorders, cancer, birth defects and even death in some cases. Some of the cancer causing are this; Dioxin is formed when chlorine breaks down, and can be found in both water and air. Dioxins are known human carcinogens and endocrine disruptors. One dioxin has been classified by the International Agency for Research on Cancer (IARC) and the Environmental Protection Agency (EPA) as a known human carcinogen. Organic solvents are a class of chemicals that includes chlorinated and other solvents, including toluene, methylene chloride, trichloroethylene and formaldehyde. Sources of exposure include outdoor and indoor air pollution, waste incineration, cleaning products and some cosmetics. They are also used in the manufacture of computer parts. Many pesticides that are included in the fluid, including herbicides and other pest-killing poisons, have been labeled as human or animal carcinogens. A report demonstrated that lifetime use of residential pesticides may be associated with an increase

What are the harmful effects of bad ozone and what is being done to reduce the ozone pollution?

When the industrial revolution start, the gases that the factory produce harm the ozone layer, but they don’t know, so this situation continues for 5 years, than the government realize that this is a situation, then

Bromide ions are released from methyl bromide when the sun’s UV light hits volatile methyl bromide in the air. A bromide’s strong pull breaks bonds between ozone (O3) and gains a single bond with oxygen. In the reaction between methyl bromide and ozone, bromide catalyzes ozone’s destruction by stealing single oxygen atoms, preventing ozone from reforming. A healthy ozone layer rebuilds itself by bonding oxygen molecules to single oxygens to form ozone; however, methyl bromide prevents this process from occurring.13

Climate change is one of the central topics in current environmental research. Earth‘s climate is highly dependent on the atmospheric radiative balance. However the atmosphere itself is dependent on the solar radiation input and output, clouds, the abundance and distribution of trace gases and aerosols. Aerosols are the globally distributed specks of matter that can be described based on their shape, size and chemical composition. Despite their relatively small size these globally distributed specks or particles when found in the atmosphere have the ability to strongly influence both the transfer of radiation energy and special distribution of latent heating thus influencing the weather and climate.

Ozone layer depletion is simply the reduction of the amount of ozone in the stratosphere. It has been determined that global stratospheric ozone levels have declined to mean that the ozone layer is changing. The ozone has a large

The Environmental Protection Agency queues in on and monitors six criteria pollutants that enter the atmosphere and can be potentially dangerous to humans. These pollutants “pose especially great threats to human health,” (Withcott & Laposata, 2012, p. 283). They are carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2), tropospheric ozone (O3), particulate matter, and lead (Pb). As mentioned each pose grave threats to humans. The measurement of tropospheric ozone routinely surpasses the recommended safe level by the EPA, (Withcott & Laposata, 2012).

The ozone is a gas in the atmosphere that protects all living things on Earth from damaging ultraviolet rays that come from the sun. With the ozone layer depleting, it would be difficult for anything to survive much longer or not at all. The ozone acts as a shield to protect living things from absorbing the ultraviolet ray and keeps them from being damaged. Many man-made materials are causing the ozone layer to deplete at a faster rate. The author states, “Emissions of chlorine and bromine from CFCs and halons are to blame for excessive stratospheric ozone depletion” (Ivanovich and Calm). This type of emission is going into the atmosphere and is breaking down the ozone layer. Consequently, this is resulting in the

The atmosphere is an amazing creation. It contains many things that help make this world a place where we can live. The atmosphere contains ozone. That helps protect our skin from harmful sun rays. Many layers make up our atmosphere. There are five main layers, the troposphere, stratosphere, mesosphere, thermosphere, and lastly the exosphere. Each layer has a different purpose. Clouds are located in the atmosphere and are a big part of the water cycle. There are different types of clouds and they all have different effects. Conduction and convection also play a big part in how we live our lives today.

Many of us might not understand how important the ozone layer is to our planet. So that is why we should take more care of our environment so we don’t deplete our ozone layer even more. To some this topic may not be important and they don’t understand what affects these dangerous chemicals can have on our environment. Hopefully reading this they will want to take better care of our planet for our future generations.

Air pollutants refer to those substances that interfere with the natural composition of the atmosphere and are harmful to living organisms. Chlorofluorocarbons are primary pollutants as far as air purity is concerned. They are contained mainly in aerosols and cooling liquid used in refrigerants. They include carbon monoxide, sulfur dioxide and other chlorine substances. Carbon monoxide is produced when compounds containing carbon such as fossil fuel are burnt in insufficient supply of oxygen. A case in point occurs when fuel used to power automobiles produce carbon monoxide that is directly injected into the atmosphere. This gas has negative impacts on the blood system when inhaled by humans and other organisms. For instance, carbon monoxide

The ozone layer protects the Earth from the ultraviolet rays sent down by the sun. If the ozone layer is depleted by human action, the effects on the planet could be catastrophic.Ozone depletion describes two distinct, but related observations. One is a slow, steady decline of about four percent per decade in the total volume of ozone in Earth's stratosphere since the late 1970s. The other is a much larger, but seasonal, decrease in stratospheric ozone over Earth's Polar Regions during the same period. Only a few factors combine to create the

What we now call the ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson. Caroline et al suggests the earth’s atmosphere has five layers; they are placed in order of closest and deepest to farthest and thinnest. They include the troposphere, stratosphere, mesosphere, thermosphere and exosphere. (Tran, Caroline, Dan Chong, Anne Keith, and Jordan Shively. "Depletion of the Ozone Layer." UC Davis ChemWiki. STEMWiki Hyperlibrary). Ozone is a naturally occurring molecule containing three oxygen atoms. These ozone molecules form a gaseous layer in the Earth’s upper atmosphere called stratosphere. (The Columbia Electronic Encyclopedia, 6th ed. “ozone layer”. Columbia University Press) this extends from six miles above the Earth’s surface to 31 miles. In the stratosphere the ozone layer acts as the earth’s sun screen; as ozone take in solar ultraviolet radiation strongly, especially at wavelengths less than about 310 nm in the ultraviolet-A and Ultraviolet-B parts of the spectrum. Ozone thus acts as a strainer, preventing potentially detrimental Ultraviolet radiation from reaching the surface which can causes skin cancer and genetic damage. (Hester, Ronald E, and Harrison, Roy M, eds. Causes and Environmental Implications of UV-B Radiation. Cambridge, GBR: Royal Society of Chemistry, 2000. ProQuest ebrary)

Ozone depletion in the earth’s atmosphere is under constant scrutiny by the American press and people. Perhaps the concern is warranted; the ozone layer protects life on earth by absorbing 97-99% of the damaging ultraviolet radiation from the sun (U.S. Environmental Protection Agency, 2006). Over the past twenty years, the stratospheric ozone has decreased approximately 3% per decade. Possible concerns have been raised about loss of polar caps, DNA damage, increased human health risks, and environmental process disturbance. Emerging research has helped clarify effects of global ozone depletion. Three areas that have received recent scientific attention include UV effects upon macroalgae,

Ozone occurs in two layers of the atmosphere. The layer closest to the Earth's surface is the troposphere and the other layer is the stratosphere. The ozone layer contains less than ten parts per million of ozone, while the average ozone concentration in Earth's. It is shaped in the stratosphere when ultraviolet light from the sun splits an oxygen molecule into two single oxygen atoms. Each of those oxygen atoms then binds with an oxygen molecule to form an ozone molecule. Ozone layer that can guard everything living on the Earth from harmful ultraviolet rays from the sun. Without Ozone in the atmosphere, it would be very hard for anything to survive on the surface.
