Europe Nitrogen Pollution
Continuing concern over the appearance of nitrogen in different ecosystems, not just the consequences that lead to aggravate the greenhouse effect causal, but also by an effect known as Acid Rain, which has serious implications for the development of different species, as well that cause serious crop damage.
This time, the novelty is that it was found that nitrogen pollution, mainly from the activities of industry and the use of various nitrogen compounds in agriculture, have caused changes in at least 60% of the most important wildlife in Europe.
The amount of nitrogen compounds detected is above sustainable levels, and has predicted that this number would increase gradually in the absence of solutions to be implemented quickly and persistently.
To this is added to be taken other conservation measures to the affected sites, and adding a comprehensive analysis of how it has affected the biodiversity of different regions, then plan measures to protect the species most affected.
Increasingly negative consequences are projected and detected, and all the destructive action of the hand of man.

Causes of Acid Deposition
Some industries or power plants that use low-quality fuels, the atmospheric air releasing large amounts of sulfur and nitrogen oxides. These contaminants can be transported over distances of hundreds of kilometers by air currents, especially when emitted into the atmosphere from very high chimneys that reduce pollution in the vicinity but the move to other places.
In the atmosphere of nitrogen and sulfur oxides are converted into nitric and sulfuric acid back to earth with rain or snow precipitation (acid rain). Other times, though it does not rain, are falling solid particles with acid molecules attached (dry deposition).
Normal rain is slightly acidic and lead forms carbonic acid when carbon dioxide from the air dissolves in the water that falls. Its pH is usually between 5 and 6. But in areas with polluted air by acidifying substances, the rain has pH values ??of 4 or 3, and in some areas where fog is acidic, the pH can be 2.3, ie similar the lemon juice or vinegar.
