What is Acid Rain?
It is rain whose Ph has decreased and therefore
been turned acidic after having mixed with
sulphur or nitrogen dioxide in the atmosphere.

The Formation of Acid Rain
Burn fossil fuels in
Transport, Industry,Homes, power stations
The rest reacts with sunlight and
ozone in the atmosphere; nitric acid(HNO3), and sulphuric acid (H2SO4)are produced
Gas, Oil, Coal
Some falls back to
Earth close to the dryparticles, gas andaerosols.NO2 SO2
It is dissolved in themoisture and resultsinto acid rain

How is nitrogen andsulphuric dioxide formed? Burning Fossil Fuels (coal oil or
gas)
Sulphur dioxide dissolvesin rain, making it more
acidic.
It lowers its pH to 5.8
When sulphur is burned
it reacts with oxygen in
the atmosphere and it
produces Sulphur
dioxide.

Effects On Forests
Acid rain can have terrible effects on a forest. The acidtakes away important minerals from the leaves and the soil.
Minerals are like vitamins for trees and plants. Withoutthem, trees and plants cannot grow properly. They lose theirleaves and become very weak. They are no longer strongenough to fight against illnesses and frost. They become
very ill and can even die.

Effect on Fish
During the winter dangerouslyacidic pollutants have built up inthe snow and when the snowmelts in spring all the acid drainsinto the water system killing manyfish.
Even those who survive sufferfrom Acid Stress
Other affect on the fish arereduced egg composition,decreased growth.
These mass fish disappearancesaffects the birds and eventuallyour whole ecosystem.

Impact on Society
Our historical
monuments and
statues are being
decayed by acid rainwhich could deprive
future generations
from seeing such
beautiful sculpturesand buildings.

Health Problems
Sulfur dioxide (SO2) andnitrogen oxides (NOx) gasesturn in to particles that canbe inhaled deep intopeople's lungs.
Asthma and Bronchitis.

Decide which fossil fuels burn more
clearly.
Research new less-pollutant methods
Fit scrubbers into factorys chimneys,
which are chemical filters that remove
impurities such as sulphur from smoke.
The government can take action.
Cars can be fitted with special converters
which remove dangerous chemicals

Why do some factory ownersrefuse to try new environmentallysafe methods?
1.It is an additional pay they have to make
2. Their profits may go down.
3. They are not aware of the dangers of acid rain.

Walk instead of
drive.
Avoid burning
fires.
Recycle and reuse as much as
possible.
Avoid using air conditioner or
leaving the computer on.
