Contamination Atmospheric

The atmosphere is an open system in contact with the surface of the planet with very considerable dimensions. All air pollution sources that release pollutants into the atmosphere, whether particles or gases, starts from the air emissions from different sources emitting pollutants into the atmosphera .The wind, Turbulence in the air, the rain, the relief geographical clearly involved in the distribution, dispersion or concentration of pollutants. The consequences for the estimated air pollution scientists of the Intergovernmental Panel
Climate Change are: - average temperature increase of 1 to 3.6 degrees Celsius in the next century - desertification in certain areas of the planet - diminution of ozone - acid rain - torrential rains in other areas - rising sea levels between 15 and 94 cm, flooding densely populated areas today - dissemination of certain tropical diseases in temperate zones today.
The atmosphere that surrounds our planet, there are a number of gases (mainly water vapor and carbon dioxide) having a greenhouse effect, that is, absorbing and re-emitting infrared radiation, preventing part of this escape from the earth, and contributing to the average temperature of the air surface of the planet is about 15º C, a temperature suitable for life. The greenhouse effect is therefore a natural phenomenon of the atmosphere. The current problem is that many of these natural greenhouse gases in the atmosphere has increased and that have led to more greenhouse gases do not naturally present in the atmosphere. This change threatens the
composition, resilience and productivity of natural ecosystems. Effects:, outside of the ozone layer: the same effect on atmosphere, global long-term effect. - Photochemical smog; local effect in the short term. - Acid rain; local effect in the short term. - Callendar Effect - Global Warming
Acid rain is a phenomenon consistent with rain falling pH levels lower than normal. It
mainly due to the reaction of water with the products of sulphur and nitrogen molecular incurred during combustion, such as nitrous oxide NO2, NO3 nitric oxide or sulphur dioxide SO2 which when combined with water generate nitrous acid HNO2, HNO3 nitric acid and sulphuric acid H2SO4. The causes of acid rain are sulphur dioxide (SO2) and nitrogen oxides (N2O3 and N2O5) that is generated by the combustion of fossil fuels, and in combination with moisture and produce rain water droplets sulphuric acid (H2SO4) and nitric acid (HNO3) burning leaves and vegetation that basically affects plant ecosystems, such as forests, but also may affect lakes and reservoirs. Acid rain can have harmful effects on plants, animals and buildings. Cause • Metal corrosion in metal structures such as bridges or erosions in stone buildings. It also burns the leaves of the plants and vegetables that basically affects ecosystems, such as forests, but also may affect lakes and reservoirs .The-acidifying effects of polluted rain can turn a lush forest a cemetery of dead trunks. Sulphur dioxide and nitrogen oxides that fall as rain, settled on the leaves of plants and act as an acid piercing passes and killing the plants, trees, flowers ...
The ozone depletion is an effect of air pollution on Earth which consists of a reduction of ozone in the stratosphere (upper layer of the atmosphere) supposedly due to emission into the air of those substances that react and decrease ozone.
The most accurate theory until now is that the ozone depletion in the stratosphere is due to increased chlorine in the atmosphere, combined with ozone and destroys. The ozone layer protects the plants and living organisms on the planet of the solar UV radiation, therefore, its reduction can cause damage to the planet.
