WHAT IS ACID RAIN?

Acid rain is rain that is more acidic than normal. Sulfur dioxide and nitrogen oxides, the major sources of acid rain.

Measurement surement of acidit dity y of 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

• xides 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.

Effects Of Acid Rain a). On Non-Living b). On Living c). On Soil

a) a). Effe fect ct on non-livin living

The Taj Mahal in Agra, suffering from sulphur di oxide, sulphuric acid and other fumes pollutants released from Mathura Refinery. Acid Rain causes extensive damage to building, statues, bridges, & structural materials of marble, lime stone, etc.

b). Effects ects on Living ing

 The sulfur dioxide and nitrogen oxide gases,

causes respiratory diseases like asthma, chronic bronchitis, etc.

 Acid Rain increases the acidity of lakes & rivers,

which is directly effect the aquatic ecosystem.

c) c). On n Tre rees es & So & Soil

 Acid Rain dissolves all the nutrients and the useful

minerals for the tree to grow.

 Weakens the process of photosynthesis.

Soluti tion n Of Acid d Rain

 Fit scrubbers into factory’s chimneys,

which are chemical filters that remove impurities such as sulphur from smoke.

Soluti tion n Of Acid d Rain

 Cars can be fitted with special

converters which remove dangerous gases nitrogen oxide.

• Reduce the amount of electricity we use

Conclusiones

 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.
