This document discusses air and noise pollution. It identifies major causes of air pollution like factories, vehicles, and wildfires. Air pollution leads to issues like smog, acid rain, and global warming. It also negatively impacts human health, causing respiratory diseases. Noise pollution is unwanted sound that disrupts daily life. Common sources include vehicles, construction, and industrial activity. Noise pollution has auditory, physiological, and psychological health effects on humans and disrupts wildlife behaviors. Solutions proposed to address both issues include using renewable energy, planting trees, improving public awareness, and enforcing regulations.

1. Presentation on
AIR & NOISE POLLUTION

2. Air Pollution
AND
NOISE POLLUTION

4. What are the main causes for the air pollution?
• Factories
• Automobiles
• Energy sources
• Wild fires
• Volcano
• tornadoes

5. • Smog
• Acid rains
• Greenhouse effect
• Hole in the ozone layer

6. • It’s more dangerous
than the outdoor
pollution, because we do
everything in enclosed
environments where air
circulation may be
restricted.
• There are many sources
of indoor air pollution:
tabacco smoke, cooking
and heating appliances,
and vapors from
building materials.

7. •Global warming
•Respiratory disease
•Plants die

8. -Some individuals are
much more sensitive to
pollutants than are
others.
-Air pollution can affect
our health in many ways
with both short-term and
long-term effects.

9. -Air pollution prevention
efforts of companies have
generally focused on waste
reduction, reuse and
recycling.
-So to solve these problems
and to get over them we
can change our lifestyles.

10. Use of solar energy
Use safe cars
Plant more trees

12. WHAT IS NOISE POLLUTION?
Sound that is unwanted or disrupts one’s quality of life
is called as noise. When there is lot of noise in the
environment, it is termed as noise pollution.
Sound becomes undesirable when it disturbs the
normal activities such as working, sleeping, and during
conversations.
It is an underrated environmental problem because of
the fact that we can’t see, smell, or taste it.
World Health Organization stated that “Noise must be
recognized as a major threat to human well-being”

13. Sources of Noise Pollution
• Industrial
• Loudspeaker
• Construction work
• Road Traffic
• Trains
• Aircrafts
• Radios and Microphones
• Agricultural Machines
• Defence Equipment

14. Effect on human health…..
• Auditory effects interfering with hearing; auditory fatigue and deafness.
• Physiological effects affecting biological functions; anxiety, neurosis, insomnia, dizziness,
nausea, fatigue, visual symptoms, hypertension, cardiovascular symptoms, liver changes,
nervous symptoms, changes in skin, fast irregular heart beats (tachycardia).
• Endocrine and hormonal changes relating to stress and noise levels. i.e. raised adrenaline and
cholesterol. Noise causes blood vessels to close cutting down blood supply to the fingers and
toes. Respiratory changes occur due to noise.
• Psychological effects; physical and mental fatigue, loss of concentration, lower efficiency,
reduced output, absenteeism, higher rates of accidents, behavioural changes, errors at work,
loss of sleep, psychosomatic disorders, diseases related to stress, mental illness, aggravation
of existing stress problems and mental illness, neurotic effects, rage anger, crime.
• Non-auditory effects interfering with social behaviour; problems with communications, sleep,
recreation, mental equilibrium (peace), and the ability to concentrate at work.

15. Noise can have a negative effect on humans, domestic
and wild animals, ecological systems, buildings and
other structures.
Effects of noise on wildlife
Reduced migration of birds and other animals.
Loss of food habitats if animals are driven away.
Animals in city zoos tend to become lethargic and
their health deteriorates.
Animals tend not to reproduce, which threatens
their survival.
Other effects include duodenal ulcers, atrophy of
the thymus gland, and changes to adrenal glands.
Effects of noise on structures
Physical effects from noise include: vibration to
buildings, damage to glass windows, plaster cracking,
damage to building foundations. Jet aircraft have
damaged roads and buildings.
Environmental Effect

16. Health Effects
• There are direct links between noise and health. Also, noise
pollution adversely affects the lives of millions of people.
• Noise pollution can damage physiological and psychological
health.
• High blood pressure, stress related illness, sleep disruption,
hearing loss, and productivity loss are the problems related to
noise pollution.
• It can also cause memory loss, severe depression, and panic
attacks.

17. Solutions for Noise Pollution
• Planting bushes and trees in and around sound
generating sources is an effective solution for noise
pollution.
• Regular servicing and tuning of automobiles can
effectively reduce the noise pollution.
• Buildings can be designed with suitable noise absorbing
material for the walls, windows, and ceilings.
• Workers should be provided with equipments such as ear
plugs and earmuffs for hearing protection.

18. Solutions for Noise Pollution
• Similar to automobiles, lubrication of the machinery and servicing should
be done to minimize noise generation.
• Soundproof doors and windows can be installed to block unwanted noise
from outside.
• Regulations should be imposed to restrict the usage of play loudspeakers
in crowded areas and public places.
• Factories and industries should be located far from the residential areas.
• Community development or urban management should be done with long-
term planning, along with an aim to reduce noise pollution.
• Social awareness programs should be taken up to educate the public about
the causes and effects of noise pollution.

19. Noise pollution often persists because only five
to ten percent of people affected by noise will
lodge a formal complaint.

20. Many people are not aware of their legal right to quiet and
do not know how to register a complaint.

21. conclusion
If everyone would
help to save the
earth we would
live in a safe
environment!
