the ppt is about different types of pollutions in World. Air pollution, noise pollution, water pollution and soil pollution I descried about types of pollutions and the causes of pollutions and also the steps to overcome types of pollution .
I have uploaded images about different types of pollutions.
3. INTRODUCTION:-
WHAT IS POLLUTION?
The release of pollutants into the global environment is called pollution.
Pollutants can come from both humans and nature , such as garbage and
volcanic ash.
Pollution comes in many forms including air pollution ,water pollution
,and noise pollution .
Therefore everyone should be aware of pollution and its effects and how to
successfully reduce it .
Just like a balanced diet our environment requires a balanced mixture of all
substances.
Any substance above that pollutes the environment.
4. TYPES OF POLLUTION:-
There are four types of pollution :
AIR POLLUTION
WATER POLLUTION
NOISE POLLUTION
SOIL POLLUTION
Now let us discuss about these types of pollution in detail.
6. INTRODUCTION:-
Air pollution happens when dangerous or excessive amounts of pollutants are
released into the environment .
Such as, smokes, hazardous gases from industry , and oxides produced from cars
the burning of solid wastes etc.
A realistic example of air pollution is the pollution causes by fire crackers following
Diwali.
Now-a-days , a toxic and heavy gases are releasing from industries .
Industrialisation and modernization are to be blamed for the present situation of
air pollution.
Industries such as ,Thermal power plants, cement , steel ,mines, emit chemical
pollutants into the air and that causes air pollution.
7. EFFECTS ON HUMANS:-
People experience a wide range of health effects from being exposed to air
pollution.
Effects can be broken down into two types.
1. Long-term effects.
2.Short-term effects.
8. LONG -TERM EFFECTS:-
Long term effects of air pollution can last for years or for an entire lifetime.
They can even lead to a person’s death.
Long-term health effects from air pollution include heart diseases, lung
cancer, and respiratory diseases such as emphysema.
Release of dust from the asbestos industry causes asbestosis .
Recent studies have shown that air pollutants also cause birth effects .
Air pollution can also cause long term damage to people’s nerves , brain ,
kidneys, and other organs .
9. SHORT-TERM EFFECTS:-
Short- term effects of air pollution are temporary that include illness, such
as pneumonia and bronchitis .
They also include discomfort such as irritation to the nose , eyes , throat
and skin
Air pollution can also cause headaches, dizziness, and nausea.
Bad odours from factories , garbage, or sewer systems are also considered
as air pollution too.
These odours are less serious but still unpleasant .
10. EFFECTS ON THE ENVIRONMENT :-
Like people, environment also facing a major problem with respect to
pollution.
Air pollution particles eventually fall back to Earth.
This can kill crops or reduce their yield it can also kill young trees and
other plants.
Sulphur dioxide and nitrogen oxide particles in the air can create acid rain
when they mix with water and oxygen in the atmosphere.
When acid rain falls to Earth, it damages plants by changing soil
composition.
It also degrades water quality in rivers , lakes and streams ; damages crops
and can cause buildings and monuments to decay .
12. INTRODUCTION:-
Water pollution is a significant problem for humans right now.
Water is being contaminated by various foreign matters including
sewage waste ,
pesticides , home and agriculture trash, industrial or factory waste and
other wastes.
Water is thus losing its quality.
Nearly 80% of wastages from cities and town in India is diverted to
rivers .
In this way , rivers are getting polluted .
13. EFFECTS ON HUMANS :-
Water is becoming unfit for usage by humans beings.
Sewage water is also directed into the rivers which cause development of
various bacteria in the water making them even not suitable for bathing.
The availability of drinkable water is significantly impacted .
Contaminated water and poor sanitation causes skin diseases , cholera,
diarrhoea , and typhoid fever to humans .
Recent studies have shown that more than 50 kinds of diseases are caused
by poor drinking water quality.
According to WHO survey about 2 billion have no option but to drink the
contaminated water.
14. EFFECTS OF THE BIODIVERSITY:-
Water pollution causes the decrease of oxygen content in water which leads
to the death of aquatic animals.
And that impacts on the Biodiversity .It leads to destruction of biodiversity
due to the proliferation of phytoplankton in lakes.
And the major impact is contamination of the food chain .
Due to water pollution the whole food chain is impacted as water is the
main use of livestock farming, and agriculture can introduce toxins into
foods.
Which are harmful to our health when we are eaten .
According to UN about 1000 children die per day due to diarrhoeal
diseases.
16. INTRODUCTION:-
The lighting of fireworks , running of industries and the playing of music
over
loud speakers especially during festival season all contribute to noise
pollution.
If it isn’t controlled, it may also have an impact on how the brain functions .
Due to high volume of vehicles on road , noise pollution is increasing.
This is concerning for people who live in cities and highways .
Humans who are exposed to noise pollution will develop high BP, stress,
hearing loss , anxiety and aggression.
Though noise pollution is a major issue, no laws are existing in many cities
of the world to control it .
17. EFFECTS OF NOISE POLLUTION :-
Some of the most prevalent elements brought on by noise pollution include the
following :-
Headaches
The issue with reasoning and changing behaviour.
Elevated blood pressure
And hearing loss.
Anxiety and stress etc…
19. INTRODUCTION:-
A sizable fraction of the Indian population works in agriculture sector .
As apart of farming , farmers use a range of fertilizers , herbicides , and
other chemical substances.
This further contaminates the soil and it leads to loss of fertility in soil
which is unsuitable for growing crops .
In addition to this soil pollution happens when authorities dump
household or commercial trash on the ground .
As a result mosquito reproduction is encouraged , which promotes the
spread of diseases like dengue and malaria.
20. EFFECTS OF SOIL POLLUTION :-
Soil is the foundation of the earth on which we walk , travel, grow
vegetables and grains and nourish us .
But chemical farming degrades soil quality , and many hazardous
substances come into contact with our body.
And this finally causes various skin diseases which are unavoidable.
The most common illness caused by soil contamination are :-
1. Blood cancer
2.Liver and kidney failure
3.Loss of fertility
21. METHODS TO REDUCE POLLUTION:-
More trees should be planted.
Food should be consumed in biodegradable containers.
Avoid disposing of industrial trash in waterways such as rivers , lakes etc.
Use of electric vehicles or cycles.
Reduce the use od detergents.
Reduce the usage of single use plastic .
Utilization of renewable energy instead of fossil fuels.
Filter the waste water before discharging it industry.
22. CONCLUSION :-
So far now we have discussed about the pollution in India and how it
effects the humans and biodiversity.
So by taking the points into consideration we have to follow some steps :-
Reducing the use of plastic .
Planting more and more trees as possible .
Use of electricity instead of fuels etc..
If we follow this steps the pollution may be under some control.
