The presentation discusses environmental pollution, defining it as the introduction of contaminants that adversely affect ecosystems and human health, focusing on types like air, water, and noise pollution. It outlines the causes, control measures, and relevant environmental laws, including the Environment Act of 1986 and the Water Act of 1974, which regulate emissions and pollution levels. Various sources of pollution from industrial, agricultural, and domestic activities are highlighted, along with methods to mitigate their impact.

2. • WHAT IS POLLUTION?
• Pollution is the introduction of contaminats
into the natural environment that cause
adverse change, in the form of killing
life,toxicity of environment & damage to
ecosytem as well as our surroundings

3. TYPES OF POLLUTIONS:-
1-AIR POLLUTION
2-WATER POLLUTION
3-NOISE POLLUTION
4-ENVIRONMENTAL LAWS FOR
CONTROLLING POLLUTION

4. AIR POLLUTION-
• Air pollution is the addition of particles,
gases & chemicals into the atmosphere
that have potential to affect human health,
health of animals, vegetations & natural
resources

5. CAUSES OF AIR POLLUTION
• Combustion(of natural gas, petroleum,
coal & wood in industries,automobiles,
aircrafts etc.)
• Metallurgical processing(mieral
dust,fumes containing fluorides,sulphides
etc.)
• chemical industries
• processing industries(like cotton
textiles,wheat flour mills)
• welding, stone crushing etc

6. CONTROL OF AIR POLLUTION
• Low sulphur fossil fuel
• reduction in emissions
• zoning of industries away from human
settlements
• destroying pollutants by thermal or
catalytic combustion
• changing pollutants to less toxic forms
• by precipitation of pollutants
• uses natural gases like LPG

7. WATER POLLUTION-
• It is degradation of quality of water due to
addition of substances(inorganic, organic,
biological) which is harmful for human use
& growth of aquatic biota.

8. SOURCES OF WATER POLLUTION
• NATURAL SOURCES- clay & slit from soil
erosion,leaching of minerals, falling of
organic matter from banks.
• MAN-MADE SOURCES-
1-muncipal waste water
2-industrial waste water
3-domestic sewage
4-surface run off( contain pesticides &
fertilizers)

9. CONTROL OF WATER POLLUTION-
• biodegradation of domestic sewage
• suspended, soild particles & inorganic
material can be removed by use of filter
• indusrial effulents under various treatment
to lower pollutants rate
• any type of waste material does not
discharge into water bodies
• agriculture run off water should be
minimised
• in industry there must be a water
treatment plant

10. NOISE POLLUTION
• Noise pollution is excessive noise that
may distrupt the activity or balance of
human life.
• noise or pollutant sound has a value of
80db(deciBel) & above.

11. SOURCES OF NOISE POLLUTION-
• various industries such as textile mills, printing
presses, engineering establishments.
• agriculture machines like
tractors,harvesters,tubewells etc.
• defence equipments such as tanks,shooting
practices,explosions.
• transport vehicles
• public address systems like loud speakers.
• dynamite blasting
• cracker used at ocassions like marriages &
festivals
• stone crushing, construction work etc.

12. CONTROL OF NOISE POLLUTION-
• Decibels meters
• noise pollution control laws
• green mufflers or green belt vegetation
• ear plugs & ear muffs
• permissible time & sound level for use of
crackers
• sound diversion

13. ENVIRONMENTAL LAWS FOR
CONTROLLING POLLUTION-
1-ENVIRONMENT ACT,1986 - control of
environmental pollution by setting up of
central & state pollution control boards.
-the board check the emission & effulents by
various industries.
-the act encompasses pollution limit of
air,water,soil & noise.
-rules have been framed under this law from
time to time such as-
: hazredeous wastes rules,1989
: noise pollution rules,2000
: Biomedical Waste Rules, 1998

14. Water Act( Prevention & control of Pollution)
Act,1974.
• it specifies quality of water for various
purposes, ways & means to control water
pollution & prevention of its effect on
human health & health of other biological
entities.

15. Air ( Prevention & Control Of Pollution)
Act,1981
• this act meant for preserving quality of air,
controlling air pollution & preventing effect
of air pollutants.
• By an Amendment in 1987, noise was also
recognised as an air pollution.
