Preventing Air Pollution
Air Pollution is a problem nation wide. The pollution hangs over our
cities and is harmful and destroys living things and materials. Diesel
exhaust is one of the most dangerous sources of air pollution. This
type of pollution comes from on road vehicles such as large trucks and
buses although factories, construction equipment and farms are big
polluters too. Pollution from diesel engines contributes to about 80%
of the added cancer risk from toxic air pollution nationwide. A main
pollution problem has typically been high levels of smoke and sulphur
dioxide arising from the burning of smoke and sulphur dioxide arising
of sulphur containing fossil fuels, such as coal, oil, and gas for
domestic and industrial purpose. Here are the equations for the gases
Sulphur+oxygen+water = sulphuric acid
This is very bad to breath in and additionally destroys rubbers and
metals. It comes from fossil fuels.
Carbon + oxygen = carbon monoxide
This is a very poisonous gas, which comes from vehicles.
Furthermore soot is a common air polluter, which mixes with fog to
make smog, which when breathed in, is very bad for our lungs. It is
even most unpleasant in valleys as it hangs in the air for longer.
When the pollution goes into the air it is known as an inversion
layer, which can be transported for miles by wind killing and
destroying on its journey. When the pollution attacks things that
aren't living it can damage many things like, bike tyres, power line
insulation, paint on buildings and makes spots on car paint via acid
Scientists have discovered that air pollution from the burning of
fossil fuels especially the burning of coal, is the major cause of
acid rain, the invisible threat. Acid deposition is not a recent
phenomenon. In the 17th century, scientists noted the ill effects that
industry and acidic pollution was having on vegetation and people.
However, the term acid rain was not coined until two centuries later
when Angus Smith published a book called 'Acid Rain' in 1872. In the
1960s, the problems associated with acid deposition became an
international problem when fishermen noticed declines in fish numbers
and diversity in many lakes throughout North America and Europe. Now
Acid rain is commonly know nation wide. It takes place when discharge
of sulphur dioxide (S02) and oxides of nitrogen (N0x) react in the
atmosphere with water, oxygen, and oxidants to form various acidic
compounds. This mixture then forms a solution of sulphuric and nitric
acid compounds. Sunlight then increases the rate of these reactions.
Theses compounds then fall to the ground in either a wet form (such as
rain, snow and fog or it can fall in a dry form (such as gas
particles). Once the acid rain falls the runoff water adds those acids
to fully acid rain making...
