ACID RAIN

PRESENTED BY: NAME- AKHIL KM

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.

WHAT IS ACID RAIN?

TYPES OF ACID RAIN 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.

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.

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

CAUSES OF ACID RAIN

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.

Natural sources such as erupting volcanoes and lighting produce sulphur dioxide and nitrogen dioxide which cause to the formation of acid rain.

HOW ACID RAIN IS FORMED.

ON NON – LIVING. ON LIVING. ON SOIL.

EFFECTS OF ACID RAIN.

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

EFFECT ON NON – LIVING.

Acid rain causes extensive damage to buildings, statues, bridges, and structural materials of marble, lime stone, etc.

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 also lead to permanent lung damage.

EFFECTS ON LIVING.

ON WATER ANIMALS.

Acid rain increases the acidity of lakes and rivers, which directly effects the aquatic ecosystem.

Acid rain dissolves all the nutrients and the useful minerals for the tree to grow.

Weakens the process of photosynthesis. According to modern researches, Acid rain

leaches potassium, calcium, magnesium, etc essential elements from the top of soil and 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.

ON TREES AND SOIL.

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.

SOLUTION OF ACID RAIN.

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