million people are killed worldwide every year due to air pollution. So‚ it has shown us how seriously the tendency of air pollution all around the world. This environmental issue has brought us a lot of effects like greenhouse effect‚ acid rain and ozone layer depletion. One of the effects of air pollution is greenhouse effect. Greenhouse effect means the phenomenon whereby carbon dioxide traps solar radiation in the earth’s atmosphere. As the heat is trapped in the atmosphere‚ the temperature is rising

activity. Some of these activities cause pollution. Pollution now is a very important problem. Some of these problem are : the ozone holes‚ global warming (or green-house effect)‚ acid rain … The ozone layer is a layer of gases which stop harmful solar radiation protecting the earth. Recent research shows that there is a hole in part of the ozone layer which is caused by smoke from factories‚ car exhaust fumes‚ aerosol cans ‘cause they contain CFC. Global warming

SCI/275 August 25‚ 2013 Professor Ed Mata Atmospheric Issues In today’s society there is much pollution that can cause an individual to become very sick or death can occur from the many atmospheric issues such as ozone depletion in our society. There are many things that contribute to ozone depletion in our atmosphere as well as indoor pollution such as radon which can cause certain cancers and certain deaths. There is also a lot of indoor air pollution which can cause the same issues to an individual’s

People who live in big cities are badly affected by harmful discharge from plants and city transport and by the increasing noise level which is as bad for human health as lack of fresh air and clean water. Among the most urgent problems are the ozone layer‚ acid rains‚ global warming‚ toxic pollution of atmosphere‚ disappearance of forests‚ contamination of underground waters by chemical elements‚ destruction of soil in some areas‚ threat to some flora and fauna representatives‚ etc. One of the most

polar ice caps which increases the sea level and pose danger for the people living near coastal areas. 4. Ozone Layer Depletion: Ozone layer is the thin shield high up in the sky that stops ultra violet rays from reaching the earth. As a result of human activities‚ chemicals‚ such as chlorofluorocarbons (CFCs)‚ were released int to the atmosphere which contributed to the depletion of ozone layer.. 5.

Along with harming human health‚ air pollution can cause a variety of environmental effects: Acid rain is precipitation containing harmful amounts of nitric and sulfuric acids. These acids are formed primarily by nitrogen oxides and sulfur oxides released into the atmosphere when fossil fuels are burned. These acids fall to the Earth either as wet precipitation (rain‚ snow‚ or fog) or dry precipitation (gas and particulates). Some are carried by the wind‚ sometimes hundreds of miles. In the environment

Photochemical smog‚ or ground-level ozone‚ has been the most recalcitrant of air pollution problems‚ but reductions in emissions of sulfur and hydrocarbons may yield unanticipated benefits in air quality. While sulfate and some organic aerosol particles scatter solar radiation back into space and can cool Earth ’s surface‚ they also change the actinic flux of ultraviolet (UV) radiation. Observations and numerical models show that UV-scattering particles in the boundary layer accelerate photochemical reactions

be natural or man-made. Why are trace gases important? The most important gases in the Earth’s atmosphere are the greenhouse gases. Most abundant in the troposphere‚ these gases include carbon dioxide‚ methane‚ nitrous oxide‚ water vapour and ozone‚ so called because they are involved in the Earth’s natural greenhouse effect. This keeps the planet warmer than it would be without an atmosphere. Apart from water‚ the most abundant greenhouse gas‚ by volume‚ is carbon dioxide. Carbon dioxide gases

Benito REACTION PLAN Ways to Slow Down Ozone Depletion Global warming refers to an increase in the average temperature of the Earth as a result of the greenhouse effect‚ in which gases in the upper atmosphere trap solar radiation close to the planet’s surface instead of allowing it to dissipate into space.
