Acid rain

Rain that is more acidic than normal

is called acid rain.

In other words the precipitation

containing acid in amount more than

usual is called acid rain.

Acid rain has pH value less than 5.

Dr. Gene E. Likens discovered acid rain in North America

The English chemist Robert Angus invented the term ‘acid rain’ for the first time. He referred as the 'Father of Acid Rain’.

• Burning coal, Oil and natural gas, in power stations which use in making of electricity, gives off sulphur dioxide gas.

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

• When these gases mix with water vapour and rainwater in the atmosphere produce weak solutions of sulphuric and nitric acids – which fall as acid rain.

CAUSES OF ACID RAIN

There are intense

effects of acid rain on

various components:

1. Effects on

monuments and

sculptures..

2. Effects on trees and

vegetation.

3. Effects on aquatic

animals.

4. Effects on humans. 7

1.Many buildings are made of concrete or

stone.

2.These compounds act as bases and

react with acid.

EFFECTS ON AQUATIC ANIMALS

• Acid Rain increases the acidity of lakes

& rivers, which is directly effect the

aquatic ecosystem.

Major respiratory problems.

Asthma, along with dry cough, headache, and throat irritation can be caused by the SO2 and Nox from acid rain.

•Use energy efficient appliances.

•Use public transportation, Whenever

possible walk or use bicycle

•Buy vehicles witTurn off lights, computers,

and other appliances when you're not using

them

•h low NOx emissions, and maintain all

vehicles properly.

•Plant more trees.

PREVENTION

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. factories should have use

filters so that less pollution goes in the sky.

We have to educate the children on Environmental

issues.
