Pollution

3. Pollution
POLLUTION IS THE INTRODUCTION OF
CONTAMINANTS INTO THE NATURAL
ENVIRONMENT THAT CAUSE ADVERSE
CHANGE. POLLUTION CAN TAKE THE FORM
OF ANY SUBSTANCE OR ENERGY.
POLLUTANTS, THE COMPONENTS OF
POLLUTION, CAN BE EITHER FOREIGN
SUBSTANCES/ENERGIES OR NATURALLY
OCCURRING CONTAMINANTS.

4. Types of pollution
THERE ARE FIVE TYPES OF
POLLUTION :-
• AIR POLLUTION
• WATER POLLUTION
• NOISE POLLUTION
• LAND POLLUTION
• RADIO ACTIVE POLLUTION

Air pollution is contamination of the
indoor or outdoor environment by any
chemical, physical or biological agent
that modifies the natural
characteristics of the atmosphere.
Household combustion devices, motor
vehicles, industrial facilities and forest
fires are common sources of air
pollution.

6. • Effects Of Air Pollution
 Long-term health effects from air
pollution include heart disease,
lung cancer, and respiratory
diseases such as emphysema. Air
pollution can also cause long-term
damage to people's nerves, brain,
kidneys, liver, and other organs.
Some scientists suspect air
pollutants cause birth defects.

7. • Causes Of Air Pollution
 Vehicle emissions, fuel oils and
natural gas to heat homes, by-
products of manufacturing and
power generation, particularly coal-
fueled power plants, and fumes
from chemical production are the
primary sources of human-made air
pollution.

8. • Prevention Of Air Pollution
 Minimize air pollution from cars.
 Walk, bike or use public transportation.
 Save energy.
 Maintain your wood stove or fireplace.
 Recycle & buy recycled products.
 Consume less & choose sustainable products.
 Eat local, organic produce & less meat.
 Grow your own food.

9. water pollution
 Water pollution is the contamination of
water bodies, usually as a result of
human activities, so that it negatively
affects its uses. Water bodies include
lakes, rivers, oceans, aquifers, reservoirs
and groundwater. Water pollution
results when contaminants mix with
these water bodies.

10. • Effects Of Water Pollution
 Water pollutants may cause
disease or act as poisons.
Bacteria and parasites in poorly
treated sewage may enter
drinking water supplies and
cause digestive problems such
as cholera and diarrhea.

11. • Causes Of Water Pollution
MAIN CAUSES OF WATER POLLUTION :-
 Global warming.
 Deforestation.
 Industry, agriculture and livestock farming.
 Rubbish and faecal water dumping.
 Maritime traffic.
 Fuel spillages.

12. • Prevention Of Water Pollution
Ways to Prevent Water Pollution:-
 Pick up litter and throw it away in a garbage
can.
 Blow or sweep fertilizer back onto the grass if
it gets onto paved areas. ...
 Mulch or compost grass or yard waste. ...
 Wash your car or outdoor equipment where
it can flow to a gravel or grassy area instead
of a street.

13. noise pollution
 Noise pollution is an invisible
danger. It cannot be seen, but it is
present nonetheless, both on land
and under the sea. Noise pollution is
considered to be any unwanted or
disturbing sound that affects the
health and well-being of humans
and other organisms. Sound is
measured in decibels.

14. • Effects Of Noise Pollution
 Noise pollution adversely affects
the lives of millions of people.
Studies have shown that there
are direct links between noise and
health. Problems related to noise
include stress related illnesses,
high blood pressure, speech
interference, hearing loss, sleep
disruption, and lost productivity.

15. • Causes Of Noise Pollution
There are many sources of noise pollution, but
here are some of the main ones:
 Traffic noise.
 Air traffic noise.
 Construction sites.
 Catering and night life.
 Animals.

16. • Prevention Of Noise Pollution
 We can Reduce Noise pollution
by turning off appliances when not in
use, use of earplugs, lowering the
volume, planting more trees, regular
maintenance of vehicles and
machines etc. By controlling noise we
can control negative health effects
that noise pollution has on everyone.

17. Land Pollution
 Land pollution refers to the
deterioration of the earth's land
surfaces at and below ground
level. It is caused by the
accumulation of solid and
liquid waste materials that
contaminate groundwater and
soil.

18. • Effects Of Land Pollution
 Polluted soil, which leads to a loss of
fertile land for agriculture and a
reduction in the availability of food.
Climate change, which causes an
onslaught of disastrous problems,
including flash floods and irregular
rainfalls. The endangerment and
extinction of species in wildlife.

19. • Causes Of Land Pollution
 The Main Causes of Land Pollution.
While there are many causes of
land pollution, the main
contributors include litter, waste,
urbanization, construction, mining,
extraction, and agriculture. Let's
dive into how these different issues
lead to increased land pollution.

20. • Prevention Of Land Pollution
Land pollution prevention :-
 Cleanup. Environmental remediation consists of
removing pollution from the soil, groundwater or
surface water. ...
 Green agriculture. ...
 Sustainable forest management. ...
 Proper waste disposal. ...
 The "3 R's" Rule & Education.

21. Radio Active Pollution
 Radioactive Pollution is
defined as the increase in the
natural radiation levels caused
by human activities. It is
estimated that about 20% of
radiation we are exposed to is
due to human activities.

POLLUTION

Buildings/Soil Cosmic Food/Drinking Water

22. • Effects Of Radioactive Pollution
 Exposure to very high levels of
radiation, such as being close
to an atomic blast, can cause
acute health effects such
as skin burns and acute
radiation syndrome (“radiation
sickness"). It can also result in
long-term health effects such
as cancer and cardiovascular
disease.

23. • Causes Of Radio Active Pollution
Here are some causes of radioactive pollutants :-
 Nuclear accidents from nuclear energy generation plants.
 The use of nuclear weapons as weapons of mass
destruction (WMD).
 Use of radioisotopes.
 Mining.
 Spillage of Radioactive Chemicals.
 Tests on Radiation.
 Cosmic Rays and Other Natural Sources.

24. • Prevention Of Radioactive Pollution
 Use spill trays and absorbent covering.
 Use fume hoods for handling potentially
volatile material.
 Use glove box for handling large
quantities of volatile material.
 Wear laboratory coat, disposable gloves,
and laboratory safety glasses.
 Use gloves appropriate for the chemicals
to be handled.
