Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides from the burning of fossil fuels like coal and oil. These gases mix with water vapor and fall as rain with a lower pH. Acid rain harms forests, lakes, animals and plants. It can also cause respiratory issues for humans. Solutions include installing pollution controls on power plants, reducing electricity usage, transitioning to renewable energy, and limiting vehicle emissions.

1. ACID RAIN
Muhammad Fahad Ansari 12IEEM14
Acid rain is basically rain that has a higher acid level (low
pH) than normal rain .

2. Causes of Acid Rain
• 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.

3. THE
PROBLEM!!!

4. People couldn't live without
electricity! Therefore coal will
continue to be burnt. Also, electricity
and energy are constantly being
overused.

5. How Acid Rain Affects The
Environment
 Acid rain is an extremely
destructive form of pollution, and
the environment suffers from its
effects. Forests, trees, lakes,
animals, and plants suffer from
acid rain.
TREES!
 The needles and leaves of the
trees turn brown and fall off.

6. Humans
Humans can become seriously ill,
and can even die from the effects of
acid rain. One of the major
problems that acid rain can cause in
a human being is respiratory
problems.
Many can find it difficult to breathe,
especially people who have
asthma. Asthma, along with dry
coughs, headaches, and throat
irritations can be caused by the
sulphur dioxides and nitrogen
oxides from acid rain.

7. Research carried out in North
America in 1982, revealed that
sulphur pollution killed 51,000 people
and about 200,000 people become ill
as a result of the pollution.

8. What are
the
solutions
to acid
rain?

9. Solutions
• 1. Sulphur dioxide can be removed from power
stations chimneys but this process is expensive.
• 2. Reduce the amount of electricity we use
- turn TV's off at the mains, don’t leave on
standby.
- turn off lights when a room is not in use.
• 3. Use renewable energy like wind power, solar
panels, tidal power and geothermal energy.
• 4. Limit the number of vehicles on the roads and
increase public transport.
