4. Conclusion

3. • Acid rain is rain that is more acidic than normal.
• Any rainfall has a pH value less than 5.6 is defined as acid
rain
• Sulfur dioxide and nitrogen oxides, the major sources of acid
rain.

5. • Burning coal, Oil and natural
gas, in power stations makes
electricity, giving off sulphur
dioxide gas.
• Burning petrol and oil in
vehicle engines gives off
nitrogen oxides as gases.
• These gases mix with water
vapour and rainwater in the
atmosphere producing weak
solutions of sulphuric and
nitric acids – which fall as acid
rain.

6. • The sulfur dioxide and
nitrogen oxide gases,
causes respiratory diseases
like asthma, chronic
bronchitis, etc.
• Tiny Particles cause
difficulty in breathing for
humans and animals &
also lead to permanent
lung damage.
•On Human Health

7. • Acid Rain dissolves all the nutrients and the useful minerals
for the tree to grow.
• Weakens the process of photosynthesis.
• Acc. to modern researches, Acid Rain leaches potassium,
calcium, magnesium, etc essential elements from the top of
soil & When soil is contaminated, cereal (arable) production
crops.
• Acids activate aluminium from the soil which leaches into
water and fish die. Drinking water is contaminated.

8. • Acid Rain increases the acidity of lakes &
rivers, which is directly effect the aquatic
ecosystem.

9. EFFECT OF ACID RAIN ON TAJ MAHAL

10. • White starts to go yellow
• Precious and semi precious stones of the Taj weathered
away due to acid rain
• The sulfuric and nitric acids in the rain causes the calcite
to dissolve and makes gypsum form
• Gypsum causes the area of affected stone to turn black
and when the gypsum falls off it reveals crumbling stone

11. BEFORE AFTER

12. An example of acid precipitation damage to an outdoor statue. The statue, made of
porous sandstone, was created in 1702 as part of the gable of the entrance of the Castle
at Herten, near Reclinhausen, Germany. The left photo, taken in 1908, shows some
stains and the loss of the left hand, but most of the face and right hand were intact after
206 years of exposure. The right photo, taken in 1969, shows the loss of most of the
detail of the statue over 61 years

13. •Turn off lights, computers, and other appliances when you're not
using them
•Use energy efficient appliances: lighting, air conditioners, heaters,
refrigerators, washing machines, etc.
•Only use electric appliances when you need them.
•Keep your thermostat at 68 F in the winter and 72 F in the
summer. You can turn it even lower in the winter and higher in
the summer when you are away from home.
•Insulate your home as best you can.
•Carpool, use public transportation, or better yet, walk or bicycle
whenever possible
•Buy vehicles with low NOx emissions, and maintain all vehicles
well.

14. Acid rain is slowly destroying our planet. It is our
responsibility to make sure that we protect the earth for
future generations to enjoy.
We should stop polluting, for example riding your car just
to go to your neighbors five houses away from yours, or
factories should have filters so that less pollution goes in
the sky.
