Pollutant Sources

Air pollution or environmental contamination is the presence of chemical elements or combinations thereof at a high rate, which ínidices become harmful to health, safety of the inhabitants of the planet or well being of the same in the atmosphere. This contamination is also considered harmful from the point that prevents the natural development of plants and animals and their normal breeding, focusing directly on his untimely death, jeopardizing the preservation of the species.

Within the tested pollutants from the atmosphere must be considered:

Chlorofluorocarbons, known as CFCs, Carbon Monoxide, Carbon Dioxide, Sulfur Dioxide, methane, and ozone (when it exceeds its presence is considered normal), are the best known and studied and most influential in the atmosphere .
Rivers of ink have run explaining the harmful lead with the presence in high percentages of these chemicals on the land, but the synthesis of these are concentrated in glogal Warming and Climate Change.

Following the current climate change with Metro areas suffering drought, while others have to endure floods greater than the statistically known, the poles are affected by increased temperature glogal which will cause a melting of the polar increasing the volume of the oceans, controls the composition of the atmosphere are deepening the effects can be measured in more detail it and measure the result of preventive actions that are performed.

Controls air composition of the atmosphere, takes place both at the Metro on a sample taken in a systematic way in different places by voluntary agencies and environmentalists, as well as level of spatial (10 km troposferea. Of estratófera surface and up to 50 kms) through aerostráticos balloons, specialized satellites.

The World Meteorological Organization (WMO) is coordinating the measurements that contribute to climate change assessment developed by the Intergovernmental Panel on Climate Change (IPCC) . This group of experts comprising the UN, issues reports and technical assessments based on measurements and other scientific data related.

A range of complementary international satellite measurements on the surface. The Atmospheric Infrared Sounder (AIRES) and the Tropospheric Emission Spectrometer (TES) from NASA, along with the satellite program Infrared Atmospheric Sounding Interferometer in France (IASI) use a process called thermal emission measurements of the troposphere, few kilometers above the Earth.

Those interested in having updated information on the status of the air composition of the atmosphere, and have the same trend graphs can be found at the site of the European Agency EEA , which is displayed as an ordinary citizen can understand this important position .
