Thermal power plants generate 65% of India's electricity but have significant environmental impacts. The Yamunanagar Thermal Power Project in Haryana has 2 units totaling 600 MW of capacity. Coal fired plants require large amounts of land, water and fossil fuels and release pollutants like fly ash containing heavy metals into the air, water and soil. Long term exposure can cause health issues like Minamata disease. Mercury is released and bioaccumulates in fish consumed by humans. Alternatives like solar, wind and hydroelectric power could reduce environmental contamination.
The slide show was prepared for educating general public on ill effects of Coal based Thermal power plants, and devastation caused by mining.
Literature available through net and other sources have been referred to for the publications.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
Climate Change All over the World .pptxsairaanwer024
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity

Altered Terrain: Colonial Encroachment and Environmental Changes in Cachar, A...PriyankaKilaniya
The beginning of colonial policy in the area was signaled by the British annexation of the Cachar district in southern Assam in 1832. The region became an alluring investment opportunity for Europeans after British rule over Cachar, especially after the accidental discovery of wild tea in 1855. Within this historical context, this study explores three major stages that characterize the evolution of nature. First, it examines the distribution and growth of tea plantations, examining their size and rate of expansion. The second aspect of the study examines the consequences of land concessions, which led to the initial loss of native forests. Finally, the study investigates the increased strain on forests caused by migrant workers' demands. It also highlights the crucial role that the Forest Department plays in protecting these natural habitats from the invasion of tea planters. This study aims to analyze the intricate relationship between colonialism and the altered landscape of Cachar, Assam, by means of a thorough investigation, shedding light on the environmental, economic, and societal aspects of this historical transformation.

3. In India 65% of total power is generated by
the Thermal Power Stations.
Yamunanagar Thermal Power Project i.e
D.C.R.T..P.P(Deen Bandhu ChotuRam
Thermal Power Plant) is a project of Haryana
Power Generation Corporation limited
(HPGCL). It is situated at village Kalanor In
Yamunanagar. Its total capacity is 600 MW as
at present with two units working with
capacity.
Having two unit of 2 x 300 MW = 600 MW
6. Power generating units are

8. Fly ash contains a toxic brew of dangerous chemicals and is the
largest contributor to mercury pollution
9. Composition of Fly ash
It contains as main chemical components SiO2 (51.4
wt%), Al2O3 (22.1 wt%) and Fe2O3 (17.2 wt%; ignited
weight basis). As commonly observed, many toxic
elements and heavy metals are highly enriched in the
fly ash relative to the original coal. For example,
considerable amounts of Be (16.4 ppm), Cu (106 ppm),
Zn (578 ppm), As (40.4 ppm), Cd (2.6 ppm), Hg (18
ppm), Pb (71 ppm), and U (21.8 ppm) is found in Fly
ash.
10.
11. Water slurry is used to take the ash from the power
plant to the ash pond for disposal.
Water slowly seeps into the ground while carrying
with it the ash leachate( Lye). This Water contains
harmful heavy metals like boron, which have a
tendency to leach out over a period of time.
When fly ash comes into contact with water, leaches
into groundwater supplies which get polluted and
unsuitable for domestic use.
The release of ash pond decant into the local water
bodies- water dries up, dust nuisance, increases
turbidity, decreases primary productivity, affects
fishes and other aquatic biota
12. The exposure of
employees to high
noise levels is very high
Increased
transportation
activities due to the
operation of the power
plants lead to increase
in noise levels in the
adjacent localities.
13. Large amount of land is used
to dispose flyash from the coal
based plants
Due to this there is change in
natural soil properties. It
becomes more alkaline due to
the alkaline nature of fly ash.
Soft bodied soil workers like
earthworms will die out
Food will contain a wider
cocktail of chemicals as
farmers try to correct the poor
productivity of crops
14. Minamata disease sometimes referred
to as Chisso-Minamata disease is a
neurological syndrome caused by severe
mercury poisoning. Symptoms include
ataxia, numbness in the hands and feet,
general muscle weakness, narrowing of
the field of vision and damage to
hearing and speech. In extreme cases,
insanity, paralysis, coma and death
follow within weeks of the onset of
symptoms. A congenital form of the
disease can also affect fetuses in the
womb.
15. Minamata disease was first
discovered in Minamata city in Japan
in 1956. It was caused by the release
of methyl mercury in the industrial
Waste water from the Chisso
Corporation's chemical factory,
which continued from 1932 to 1968.
This highly toxic chemical
bioaccumulated in shellfish and fish
in Minamata Bay and the Shiranui
Sea, which when eaten by the local
populace resulted in mercury
poisoning. While cat, dog, pig and
human deaths continued over more
than 30 years, the government and
company did little to prevent the
pollution.
16. As of March 2001, 2,265
victims had been officially
recognised (1,784 of whom
had died)and over 10,000 had
received financial
compensation from Chisso.
Lawsuits and claims for
compensation continue to
this day.
A memorial service was held
at the Minamata Disease
Municipal Museum on 1 May
2006 to mark 50 years since
the official discovery of the
disease.
17. Toxicology:
Elemental (metallic) mercury and all of its compounds are toxic,
exposure to excessive levels can permanently damage or fatally injure
the brain and kidneys.
Elemental mercury can also be absorbed through the skin and cause
allergic reactions. Ingestion of inorganic mercury compounds can cause
severe renal and gastrointestinal damage.
Organic compounds of mercury such as methyl mercury are considered
the most toxic forms of the element. Exposures to very small amounts of
these compounds can result in devastating neurological damage and
death.
For fetuses, infants and children, the primary health effects of mercury
are on neurological development.
Even low levels of mercury exposure such as result from mother's
consumption methyl mercury in dietary sources can adversely affect the
brain and nervous system.
Impacts on memory, attention, language and other skills have been
found in children exposed to moderate levels in the womb.
18. Elemental Mercury is consumed by the aquatic
creatures which are later on consumed by humans
and other living beings…
19. Each year power plants and chemical facilities
create many tons of mercury pollution, which
makes its way into our homes and bodies in fish.
Two of the biggest sources of mercury pollution
are chlorine chemical plants and coal-fired power
plants. Chlorine plants, which use massive
quantities of mercury to extract chlorine from
salt, "lose" dozens of tons of mercury each year;
power plants emit around 50 tons of mercury
pollution annually. Coal is naturally
contaminated with mercury, and when it is
burned to generate electricity, mercury is released
into the air through the smokestacks.
20. The cycle of mercury in nature is complex. This illustration
summarizes how methyl mercury accumulates at the higher
levels of the food chain and becomes concentrated in fish and
animals that eat fish.
Methylmercury in the water and sediment is taken up by tiny
animals and plants known as plankton.
Minnows and juvenile fish eat large quantities of plankton over
time.
Larger predatory fish consume many smaller fish, accumulating
methylmercury in their tissues. The older and larger the fish, the
greater the potential for high mercury levels in their bodies.
Fish are caught and eaten by humans and animals, causing
methylmercury to accumulate in human tissues.
Most people are exposed to mercury by eating fish containing
mercury. There is no method of cooking or cleaning them that
will reduce the amount of mercury in a meal.
21.
22. Air borne mercury is highly toxic when inhaled. How does it
get in the air?
Metallic mercury slowly evaporates when exposed to the air.
The air in a room can reach unhealthy levels just from the
mercury in a broken thermometer;
Mercury may be released into the air when coal, oil, or wood
are burned as fuel or when mercury-containing wastes are
incinerated. The resulting mercury concentrations in outdoor
air are usually low and of little direct concern. However,
mercury in the air can fall to the ground with rain and snow,
landing on soil or in bodies of water, causing contamination.
Lakes and rivers are also contaminated when there is a direct
discharge of mercury-laden industrial or municipal waste
into the water.
When mercury enters bodies of water, biological processes
transform it to methylmercury, a highly toxic and
bioaccumulative form. Fish can absorb methylmercury from
their food and directly from water as it passes over their gills.

Nothing will be spared
contamination
26. Temperature rising……
Coal and water slurry must be heated to 800
degrees
Water, already a scarce global resource will be
needed in ever bigger quantities both at the plant
and in surrounding areas
The used slurry will be released into water
bodies and warm them, killing many sensitive life
forms
The cap of smog will mean more heat:
greenhouse effect
Enzyme activity in all life forms including human
completely stops at 48 degrees celsius
Consequences of loss in the natural pest
predator balance will create a higher occurrence
in bacteriological diseases on an epidemic scale
32. Uses of Fly ash
Fly ash is used in producing
very strong high power
concrete. Which is called Self
Compacting Concrete(SCC),
soil stabilization, fly ash fills
roads, precast products like
tiles and blocks, fly ash
bricks also called green
bricks , agricultural use ,
raising of dykes, mine filling
etc.
