2. DEFINITION OF
POLLUTION
• When Harmful Substances Contaminate
the Environment it is Called Pollution.
• Pollution refers to the very bad condition of
environment in terms of quantity and
quality .
3. Industrial Pollution &
Environmental Degradation
• Since the industrial revolution, pollution
has been a major problem affected with
the same.
4. Types of Pollution
There are Five types of Pollution
• Air Pollution
• Water Pollution
• Noise Pollution
• Thermal Pollution
• Radio Active Pollution
5. Air Pollution
• Air Pollution is a pollution that spreads
very fast and spreads in the air and
causes SKIN & LUNGS diseases.
6. Causes & Effects
Causes Effects
• Industries • Ecosystems
• Automobiles and • Health of humans,
Domestic fuels animals, plants
• High Proportion of • The atmosphere as a
undesirable gases. whole
7. Prevention
• Treating Effluents before leaving it into the
atmosphere
• Anticipate unexpected emissions and take
proactive action to prevent their release
9. Water Pollution
• It is the introduction of chemical,
biological & physical matter into large
bodies of water that degrade the quality
of life that lives in it & consumes it.
10. Causes & Effects
Causes Effects
• Effluents discharged into • Disturbs ecosystems
rivers. • Loss of aquatic life
• Oil spills, garbage, • Spread of Diseases
sewage water
11. Prevention
• Minimising use of water by reusing and
recycling in two or more stages
• Harvesting of rain water to meet water
requirements
• Treating effluents before releasing
13. What is NOISE????
Noise can be simply defined as
unwanted sound.
The sound is pleasant or not depends
upon its loudness, duration, rhythm
and the mood of the person.
14. Causes & Effects
Causes Effects
• Industries, Factory • Hearing Loss
Equipment, Generators • High BP, Stress
• Construction and civil • Sleep Disturbances
engineering works.
15. Prevention
• The Government should ensure the new
machines that Should be noise proof.
• Industries should be setup outside
residential area and not near schools.
17. Radio Active Pollution
Pollution caused by the resultant
substances from nuclear reactors and
other radioactive substances.
18. Causes & Effects
Causes Effects
• Nuclear Power Plants, • Cancer
Weapons • Swelling of Bone Joints
• Disposal of nuclear waste • Eye Problems
• Uranium Mining
19. Prevention
• Avoid Constructing Nuclear Power Plants
• Avoid Using Nuclear Weapon
• Have Proper Treatment for Nuclear Waste
• Avoid mining for Uranium to a minimal
20.
21. Measures taken by Government
Many schemes were introduced by the
government to reduce pollution.
Some of them were specific while some were
general.
22. Work of NTPC
National Thermal Power Corporation (NTPC) is a major
power providing corporation that has a pro-active approach
for preserving the natural environment.
In November 1995, NTPC became the first public utility to
bring out a comprehensive document entitled "NTPC
Environment Policy and Environment Management System".
Notas del editor
It may increase a country’s economic growth at the same time these large scale industries cause pollution of land,water,air,noise,thermal,and many other and results in degradation of environment.
High Proportion of undesirablegases, such as sulphur dioxide and carbon monoxide
In many five year plans, measures are taken to reduce pollution.Some were successful while some where not.
Refer TEXTBOOKShorten it-Amongst the guiding principles, adopted in the document, are the company's proactive approach to environment, optimum utilisation of equipment, adoption of latest technologies and continual environment improvement. The policy also envisages efficient utilisation of resources, thereby minimising waste, maximising ash utilisation and providing green belt all around the plant for maintaining ecological balance.NTPC's environment-friendly approach to power has already begun to show results in conservation of natural resources such as water and fuel (coal, oil & gas) as well as control of environmental pollution. NTPC has chalked out a set of well-defined activities that are envisaged right from the project conceptualisation stage.Performance enhancement and upgradation measures are undertaken by the organisation during the post operational stage of the stations. These activities have greatly helped to minimise the impact on environment and preserve the ecology in and around its power projects. These measures have been enumerated as follows.
