WORLD ACID RAIN AND CAUSING POLLUTANTS

1. ACID RAIN

2. 🞂 Acid rain is rain that is more acidic than
normal.
🞂 Sulfur dioxide and nitrogen oxides, the major
source of acid rain.
🞂 Acid rain’s spread, and damage involves weather,
chemistry, soil, and the life cycles of plants and
animals on the land and from acid rain in water.

3. 🞂 WET DEPOSITION:-
Wet deposition refers to acid rain, fog,
and snow.
 As this acidic water flows over and
through the ground , it affects a variety
of plants and animals.

4. 🞂 DRY DEPOSITION:-
 Dry deposition refers to acidic gases and
particles.
 About half of the acidity in the
atmosphere falls back to earth through
dry deposition.

5. 🞂 Burning coal, Oil and natural gas, in power
stations makes electricity, giving off Sulphur
dioxide gas.

6. 🞂 Burning petrol and oil in vehicle engines gives
off nitrogen oxides as gases.

7.  These gases mix with water vapour and
rainwater in the atmosphere
 Producing weak solutions of sulphuric and
nitric acids – which fall as acid rain.
 Natural sources such as erupting volcanoes
and lighting produce sulphur dioxide and
nitrogen dioxide which cause to the formation
of acid rain.

9. 🞂 ON NON – LIVING.
🞂 ON LIVING.
🞂 ON SOIL.

10. 🞂 The Taj Mahal in Agra, suffering from sulphur
dioxide, sulphuric acid and other fumes
pollutants released from Mathura Refinary.

11. 🞂 Acid rain causes extensive damage to
buildings, statues, bridges, and structural
materials of marble, limestone, etc.

12. ON HUMAN HEALTH.
 The sulphur dioxide and nitrogen oxide
gases causes respiratory diseases like
asthma, chronic bronchitis, etc.
 Tiny particles cause difficulty in breathing for
humans and animals and lead to permanent lung
damage.

13. ON WATER ANIMALS.
 Acid rain increases the acidity of lakes and
rivers, which directly effects the aquatic
ecosystem.

14. 🞂 Acid rain dissolves all the nutrients and the
useful minerals for the tree to grow.
🞂 Weakens the process of photosynthesis.
🞂 Acids activate aluminium from the soil which
leaches into water and fish die. Drinking water
is contaminated.

15. 🞂 Fit scrubbers into factory’s chimneys, which
are chemical filters that remove impurities such
as sulphur from smoke.
🞂 Cars can be fitted with special converters
which remove dangerous chemicals.
🞂 Government need to spend more money on
pollution control.

16. 🞂Acid rain is slowly destroying our planet.
It is our responsibilty to make sure that
we protect the earth for future generation
to enjoy.
