ACID RAIN - mhs10kpcsci

Acid rain is very
harmful to life. It’s
from the
atmosphere
containing of
nitric and
sulphuric acids
and it’s a mixture
of wet and dry
deposition.
Acid rain affects us in
many different ways. One
major way is our health.
Children and adults who
have asthma or breathing
problems have been
linked to acid air
pollution. Everything we
eat, drink and breathe
has at one time come in
contact with acid
deposits. The following
health problems occur
each year in the U.S. and
Canada due to acid rain.
-55 premature deaths
-1,520 emergency room
visits
-210,070 asthma symptom
days
Two chemical gases are
released into the
atmosphere, these are
sulphur dioxide and
nitrogen oxides. Those
two chemicals are
reacted with water,
oxygen and some
substances to form mild
solutions of sulphuric and
nitric acids. In the winter
the acidic solutions
spread across and move
in a really fast pace. This is
because the winds
spread these acidic
solutions, by blowing
them into the
atmosphere. Then it starts
raining.
Burning gasoline, oil and
wood releases carbon
monoxide. Once it enters
your bloodstream you will
feel dizzy, get headaches
and fatigue. This is
because the carbon
monoxide slows down the
delivery of oxygen to your
body.
Acid rain begins with
emissions into the
atmosphere sulphur
dioxide and nitrogen
oxide. Which are released
by cars, industrial
processing such as
smelting substances
down, refining and
electric power plants that
burn fossil fuels such as
coal and oil. The gases
mix with water vapour
from the clouds which
creates sulphuric and
nitric acids. This makes
rain highly acidic.
Places in south east Asia,
western south Africa,
Southern India and
Sri Lanka and even West
Africa could all be prone
to acidic rainfall in the
future.
