3.  The October 27, 1948 Donora
smog was a historic air
inversion that resulted in a wall
of smog that killed 20 people and
sickened 7,000 more in Donora,
Pennsylvania, a mill town on
the Monongahela River, 24 miles
(39 km) southeast of Pittsburgh.
 The event is commemorated by
the Donora Smog Museum
 Sixty years later, the incident was
described by The New York
Times as "one of the worst air
pollution disasters in the nation's
history".
 Even 10 years after the incident,
mortality rates in Donora were
significantly higher than those in

5.  The Bhopal disaster, also referred
to as the Bhopal gas tragedy, was
a gas leak incident in India,
considered the world's worst
industrial disaster.
 It occurred on the night of 2–3
December 1984 at the Union
Carbide India
Limited (UCIL) pesticide plant
in Bhopal, Madhya Pradesh. Over
500,000 people were exposed
to methyl isocyanate (MIC) gas and
other chemicals. The highly toxic
substance made its way into and
around the shanty towns located
near the plant.
 Estimates vary on the death toll. The
official immediate death toll was
2,259. The government of Madhya
Pradesh confirmed a total of 3,787
deaths related to the gas release.

7.  In 1978, Love Canal, located near
Niagara Falls in upstate New York,
was a nice little working-class enclave
with hundreds of houses and a
school.
 It just happened to sit atop 21,000
tons of toxic industrial waste that had
been buried underground in the
1940s and '50s by a local company.
 The site is known as the host of a 16-
acre landfill that served as the
epicenter of a massive environmental
pollution disaster that affected the
health of hundreds of residents,
culminating in an extensive Superfund

9.  Arsenic contamination of
groundwater is a form of groundwater
pollution which is often due to naturally
occurring high concentrations of arsenic in
deeper levels of groundwater.
 It is a high-profile problem due to the use
of deep tubewells for water supply in
the Ganges Delta, causing serious arsenic
poisoning to large numbers of people. A
2007 study found that over 137 million
people in more than 70 countries are
probably affected by arsenic poisoning of
drinking water.
 Arsenic contamination of ground water is
found in many countries throughout the
world, including the USA.
 Approximately 20 major incidents of
groundwater arsenic contamination have
been reported.
 Of these, four major incidents occurred in
Asia, in Thailand, Taiwan, and Mainland
China.

11.  The Chernobyl disaster, also
referred to as the Chernobyl
accident, was
a catastrophic nuclear accident that
occurred on 26 April 1986 in the
No.4 light water graphite moderated
reactor at the Chernobyl Nuclear
Power Plant near Pripyat, in what
was then part of the Ukrainian Soviet
Socialist Republic of the Soviet
Union (USSR).
 During the accident, blast effects
caused 2 deaths within the facility
and later 29 firemen and employees
died in the days-to-months afterward
from acute radiation syndrome, with
the potential for long-term cancers
still being investigated.
