There are several types of pollution, and while they may come from different sources and have different consequences, understanding the basics about pollution can help environmentally conscious individuals minimize their contribution to these dangers.

AIR POLLUTION

Air pollution occurs when the air contains pollutants such as:GasesFumesDust

AIR POLLUTION• What are the main causes of Air Pollution?

• Burning of Fossil fuels

• Agriculture activities

• Vehicle fumes

• Mining operation etc.....

SOLUTION TO AIR POLLUTION• Conserve energy

• Use public mode of transportation

• Understand the concept of Reduce, Reuse and Recycle

• Use energy efficient devices

“Water Pollution” is the contamination of the water bodies

Eg: lakes, rivers, oceans, etc.....

WATER POLLUTION

WATER POLLUTION PROBLEMS• water pollution is the major global problem.

• An estimated 580 people died in India because of water problem.

• About 90%of water in cities of China is polluted.

“Noise Pollution” is mainly caused by transportation systems, machines, motor vehicles, air crafts etc......

NOISE POLLUTION

NOISE POLLUTION EFFECTS• Outdoor sound is summarised by the world environmental

sounds

• Noise pollutions affects both health & behaviour unwanted noise can damage physical health.

NOISE POLLUTION REDUCTION• Noise mitigation: Road way noise can be reduced by using the

noise barriers limitation of vehicle speed, use of traffic control, acceleration & tyre design

LAND POLLUTION

Land pollution is caused by deforestation, agricultural activities, mining activities, overcrowded landfills, industrialization, nuclear wastes and sewage treatment. To cut back on land pollution, many steps should be taken. Individuals must recycle, reduce the use of pesticides and other harmful chemicals

Land pollution is caused by deforestation, agricultural activities, mining activities, overcrowded landfills, industrialization, nuclear wastes and sewage treatment. To cut back on land pollution, many steps should be taken. Individuals must recycle, reduce the use of pesticides and other harmful chemicals, avoid purchasing products that are packaged in excessive packing materials

LAND POLLUTION

PREVENTIONS• Don’t use pesticides if you can.

• Use a drip tray to collect engine oil.

• Buy products that have little packaging.

• Don’t dump motor oil on the ground.

increasing efficiency in energy use,use of environmentally benign fuel sources.

POLLUTION PREVENTIONS

PREVENTIONS• In the agricultural sector, pollution prevention approaches

include:

• Reducing the use of water and chemical inputs;

• Adoption of less environmentally harmful pesticides or cultivation of crop strains with natural resistance to pests; and

• Protection of sensitive areas.

PREVENTIONS• Using reusable water bottles instead of throw-aways

• Automatically turning off lights when not in use

• Repairing leaky faucets and hoses

• Switching to "green" cleaners
