2. Pollution Definition
Pollution is the introduction of contaminants into the
natural environment that cause adverse change
The presence in or introduction into the environment of a
substance which has harmful or poisonous effects
Pollution can take the form of chemical
substances or energy, such as noise, heat or light
2
3. History of Pollution
Pollution started from prehistoric times when man
created the first fires - humans burnt wood to cook food,
the smoke emitted was pollution
Metal forging a key turning point in the creation of
significant air pollution levels outside the home
But level of pollution low and absorbed by earth’s
natural systems – main pollution from animal waste,
household waste, smoke and ash
With Industrial Revolution, with the invention of machine
from printing press to vehicles, the levels and type of
pollution rose sharply
3
4. Pollutant -- Definition
A pollutant is a waste material that pollutes air, water or
soil
Substance or energy introduced into the environment
that has undesired effects, or adversely affects the
usefulness of a resource
A pollutant may cause long- or short-term damage by
changing the growth rate of plant or animal species, or
by interfering with human amenities, comfort, health, or
property values
Pollutants may be classified by various criteria:
1) By the origin: whether they are natural or man-made
(synthetic). (2) By the effect: on an organ, specie, or an
entire ecosystem. (3) By the properties: mobility,
persistence, toxicity. (4) By the controllability: ease or
difficulty of removal.
4
5. Types of Pollutants
Three factors determine the severity of a pollutant: its chemical
nature, the concentration and the persistence
Pollutants are generally grouped under two types:
Biodegradable pollutants – Biodegradable pollutants are broken
down by the activity of micro-organisms and enter into the
biogeochemical cycles. Examples of such pollutants are domestic
waste products, urine and faecal matter, sewage, agricultural
residue, paper, wood and cloth etc.
Non- Biodegradable pollutants – Non-biodegradable pollutants
are stronger chemical bondage, do not break down into simpler and
harmless products. These include various insecticides and other
pesticides, mercury, lead, arsenic, aluminium, plastics, radioactive
waste etc.
5
6. Types of Pollutants…..
Stock pollutants -- Pollutants, towards which the environment has
little or no absorptive capacity are called stock pollutants -
e.g. persistent synthetic chemicals, non-biodegradable plastics,
and heavy metals). Stock pollutants accumulate in the environment
over time
Fund pollutants -- Fund pollutants are those for which the
environment has some absorptive capacity. Fund pollutants do not
cause damage to the environment unless the emission rate exceeds
the receiving environment's absorptive capacity (e.g. carbon dioxide,
which is absorbed by plants and oceans)
Another classification of pollutants is based on its harmful effects –
Common Elements
Toxic Elements
Radioactive Elements

8. Major Types of Pollution
Air pollution
Water
Land
Noise
Marine

9. Air Pollution
Air Pollution by far the most harmful form of pollution in
our environment
The pollutants for air pollution are divided into two
categories
The first type of pollutants known as primary pollutants
are those which are produced from a certain process like
the smoke emitted from the vehicles
The second type of pollutants are termed as the
secondary pollutants and these are the ones which are
generated due to the reaction of primary pollutants with
natural air
9
12. Pollutant Standard Index (PSI)
The Pollutant Standards Index, or PSI, is a type of air
quality index, which is a number used to indicate the level
of pollutants in air.
The PSI considers six air pollutants - sulphur dioxide ,
particulate matter , fine particulate matter , nitrogen
dioxide , carbon monoxide and ozone
PSI range: 0-50 is good; in Delhi in November 2016 PSI
crossed 200 which is very unhealthy; above 300 is
hazardous
12
13. Effects of Air Pollution
Acid rain (formed in the air) destroys fish life in lakes and
streams.
Chlorofluorocarbons (CFC), released from refrigerators, air-
conditioners, deodorants and insect repellents cause severe
damage to the Earth’s environment. This gas has slowly
damaged the atmosphere and depleted the ozone layer leading
to global warming
Excessive ultraviolet radiation coming from the sun through the
ozone layer in the upper atmosphere which is eroded by some
air pollutants, may cause skin cancer in wildlife.
Excessive ultraviolet radiation coming from the sun through the
ozone layer in the upper atmosphere which is eroded by some
air pollutants, may cause skin cancer in wildlife
13
14. Water Pollution
Water pollution is the contamination of water bodies
e.g. lakes, rivers, oceans, aquifers and groundwater)
This form of environmental degradation occurs
when pollutants are directly or indirectly discharged into
water bodies without adequate treatment to remove
harmful compounds.
Water pollution affects the entire biosphere
14
15. Water Pollution – Control Measures
1)Sewage Treatment -- In urban areas of developed
countries, domestic sewage is typically treated by
centralized sewage treatment plants
2) Industrial Wastewater treatment – Effluent treatment
plants
15
16. Marine Pollution
Marine pollution occurs when harmful, or potentially
harmful, effects result from the entry into the ocean of
chemicals, particles, industrial, agricultural and
residential waste, noise, or the spread of invasive organisms
Marine pollution includes a range of threats including from
land-based sources, oil spills, untreated sewage, heavy
siltation, eutrophication (nutrient enrichment), invasive
species, persistent organic pollutants (POP’s), heavy metals
from mine tailings and other sources, acidification,
radioactive substances, marine litter, overfishing and
destruction of coastal and marine habitats
Air pollution is also a contributing factor by carrying off
pesticides or dirt into the ocean
16
17. Marine Pollution Causes
3 main types of inputs of pollution into the ocean: direct
discharge of waste into the oceans, runoff into the waters
due to rain, and pollutants that are released from the
atmosphere
When pesticides , toxic metals are incorporated into
the marine ecosystem, they quickly become absorbed into
marine food webs
Oil spills can have devastating effects. While being toxic to
marine life, polycyclic aromatic hydrocarbons (PAHs), found
in crude oil, are very difficult to clean up, and last for years in
the sediment and marine environment
Deep sea mining
17
18. Marine Eutrophication
Effect of eutrophication on marine life
Eutrophication is an increase in chemical nutrients,
typically compounds containing nitrogen or phosphorus,
in an ecosystem
It can result in an increase in excessive plant growth and
decay of the ecosystem due to lack of oxygen
Results in severe reductions in water quality, fish, and
other animal populations
18
19. Marine Pollution : Acidification
The oceans are normally a natural carbon sink, absorbing
carbon dioxide from the atmosphere
Because the levels of atmospheric carbon dioxide are
increasing, the oceans are becoming more acidic
Oceans and coastal ecosystems play an important role in
the global carbon cycle and have removed about 25% of
the carbon dioxide emitted by human activities between
2000
Rising ocean temperatures and ocean acidification means
that the capacity of the ocean carbon sink will gradually
get weaker
19
20. Land Pollution
Land pollution is any type of destruction of the Earth
It can either occur naturally or as a result of human
activities, such as industrial development, agricultural
development, coal mining, deforestation and
overcrowded landfills
Natural factors: The natural factors that cause
soil erosion includes volcanic eruptions, changes in
rainfall pattern, earthquakes, topographic changes, wind
and glacier movements.
20
21. Land Pollution….
Humans produce vast quantities of waste
Domestic waste
Toxic Waste
Radioactive waste
Industrial waste - mining
Agricultural waste
21
22. Effects of Land Pollution
Soil Erosion
Low yields
Desertification
Less land for cultivation
22
23. Noise Pollution
Noise pollution or noise disturbance is the disturbing or
excessive noise that may harm the activity or balance of
human or animal life
Noise pollution is a major problem in India. The government
of India has rules & regulations against firecrackers and
loudspeakers, but enforcement is extremely lax
It is measured in the units of decibels and is denoted by the
dB. The noise which is more than 115 dB is tolerant
The industrial limit of sound in the industries must be 75 dB
according to the world health organization. A type writer can
produce a sound at 60 dB
23
24. Causes of Noise Pollution
Industrial activity
Poor Urban Planning
Transportation and Construction
Social Events
Household Gadgets
24
25. Effects of Noise Pollution
Hearing Problems
Sleeping Disorders
Cardiac problems
Effect on Wild life
25
27. Pollution Control
Pollution control is a term used in environmental management
It means the control of emissions and effluents into air, water or soil
Pollution prevention and waste minimization are more desirable than
pollution control
Pollution Control Practices :
Recycling
Reusing
Waste minimisation
Mitigating
Preventing
Compost
27
28. Polluter Pays Principle
Around 300 BC, Kautiliya in his Arthasastra prescribed different levels of
financial penalties for causing harm to the environment
If anyone intentionally spoils the water of another ... let him not only pay
damages, but purify the stream or cistern which contains the water. Plato,
Greek Philosopher
The 'polluter pays' principle is the commonly accepted practice that
those who produce pollution should bear the costs of managing it to
prevent damage to human health or the environment
The polluter pays principle underpins environmental policy such as
an ecotax, which, if enacted by government, deters and essentially
reduces greenhouse gas emissions
The Precautionary Principle is a strategy to cope with possible risks
where scientific understanding is yet incomplete, such as the risks of nano
technology, genetically modified organisms and systemic insecticides.
28
29. Precautionary Principle
In simple terms, the PP conveys the common-sense based advice – to err
on the side of caution. The principle intends to prevent harm to humans,
environment, and eco-system at large.
Dioxin is a general term used to describe a group of hundreds of
chemicals that are highly persistent in the environment. Dioxin is formed
by burning chlorine-based chemical compounds with hydrocarbons
The major sources of dioxin in the environment include waste-burning,
paper mills that use chlorine bleaching, production of polyvinyl chlorine
(PVC) plastics, and chlorinated chemicals like pesticides
Dioxin is very toxic and has been measured throughout the globe and its
persistence, both in humans and the environment, means that future
generations will be exposed to dioxin produced today
Harm caused by dioxin to humans and ecosystems is likely to be
irreversible, or reversible only over decades
29
30. Central Pollution Control Board
The Central Pollution Control Board (CPCB) of India is a
statutory organisation under the Ministry of Environment,
Forest and Climate Change;
Established in 1974
CPCB conducts environmental assessments and research.
It is responsible for maintaining national standards under
a variety of environmental laws, in consultation with zonal
offices, tribal, and local governments
It has responsibilities to conduct monitoring of water and
air quality, and maintains monitoring data
