Air Pollution


Air polution really is more than a bad spell of ground level air
pollution, smog, respiratory illnesses, acid rain, poor visibility and general atmospheric ugliness... We have seen through pollution articles in the media that air polution also addresses upper atmosphere issues. Things like changes in the climate map, green house effect and ozone layer depletion. We hear a lot of the controversy global warming has generated. Like the well-known greenhouse effect, a projected cause of global warming and climate change. We often hear of other atmospheric problems such as stratospheric layer ozone pollution and depletion. Also increased ultra-violet chart radiation (UVB and C) reaches ground level and harms people and other life forms. Has the American government really done anything about it? This book gives you the facts.


Causes of Air Pollution

Transportation. In Europe and North America at least,
cars contribute sulphur, nitrogen and carbon based compounds into the atmosphere. They then transform into acids and other harmful components (such as those which cause global warming) more than any other type of source. Aviation, shipping and other types of transport just add more air polution to these effects. Industry. Manufacturing, packaging and support functions cause process emissions. Ones which may contain ozone destroying or even radioactive chemicals. We can have problems with fuel consumption related compounds similar to the transportation sectors. Agricultural air polution can also fall under this category. Natural Causes. Volcanoes, fires started by lightning. Also stratospheric intrusion which is natural mixing of poisonous gases from upper layers of the atmosphere, to name a few. Finally, some things are even desirable to have in the air even if they are foreign. Take music for instance. Remember the last you walked into an Italian restaurant? How the aroma(s) would completely envelop you. And speaking of fragrance, how about the benefits of Aromatherapy? Read more about it here.
