Acid
rain is a serious environmental problem that is really a lot of rethinking by
humans. This is a common problem that is gradually affecting human life. The
term acid rain was first introduced by Angus Smith when he wrote about
industrial pollution in England at 2001.But the term acid rain is not evective, the evective one is acid deposition. Acid rain can also be
interpreted as all sorts of rain with a pH below 5.6. Rain is naturally acidic
(pH slightly under 6) because of carbon dioxide (CO2) in the air that dissolves
with rain water has a shape as a weak acid. Type of acid in rain is very
beneficial because it helps dissolve minerals in the soil needed by plants and
animals.
Basically
Acid rain is caused by two air pollutants, Sulfur Dioxide (SO2) and nitrogen
oxides (NO) which are both produced through combustion. But about 50% SO2 in
the atmosphere occurs naturally throughout the world, for example, from
volcanic eruptions and forest fires are natural. While the other 50% comes from
human activities, for example due to BBF combustion, metal smelting and power
generation.
When
they burn, they make sulphur dioxide (SO2). Most sulphur leaves factory
chimneys as the gaseous sulphur dioxide (SO2) and most nitrogen is also emitted
as one of the nitrogen oxides (NO or NO2), both of which are gases. The gases
may be dry deposited–absorbed directly by the land, by lakes or by the surface
vegetation. If they are in the atmosphere for any time, the gases will oxidise
(gain an oxygen atom) and go into solution as acids. Sulphuric acid (H2SO4) and
the nitrogen oxides will become nitric acid (HNO3). The acids usually dissolve
in cloud droplets and may travel great distances before being precipitated as
acid rain.
Acid
rain affects us in many different ways. One major way is our health. Breathing
and lung problems in children and adults who have asthma and in children have
been linked to acid air pollution. Everything that we eat, drink, and breathe
has at one time come in contact with acid deposits. This could threaten our
health by making us become sick.
Acid
rain can also damage non-living things, such as buildings and statues. It can
decay building materials and paints. Worst of all, it can damage
non-replaceable buildings, statues, and sculptures that are part of our
nation’s memories that we want to last for a very long time.
There
are a lot of similarities in all of these pollutants. Most of the pollutants
are from automobiles. Automobiles release harmful smoke into the air, which
causes acid rain. Coal, oil, and gasoline are also some of the most common
causes of all of the pollutants. If people reduce the amount of these things
that they release into the air, then there will be less pollutants. Some of the
most common health problems are breathing problems, nervous system problems,
and lung problems.
