2. Environment:
Environment is the sum total of the elements of the earth system where we born, brought up and survive.
Pollution:
Pollution is derived from Latin word "polluere" which means to defile. Pollution is an undesirable change in
the physical, chemical or biological characteristics of our air, land and water that can harmfully affect human
life or that of other species, our industrial processes, living conditions and cultural assets.
Forms of pollution:
Air Pollution, light Pollution, Noise Pollution, Soil Contamination, Radioactive contamination, Thermal
Pollution, Water Pollution, Visual Pollution
Environmental pollution:
Environmental pollution is the introduction of harmful pollutants into a certain environment that make an
environment unhealthy to live in. The widespread pollutants are usually chemicals, garbage, and wastewater.
Environmental pollution is happening in multifold parts of Earth usually in the form of air and water
pollution. pollution:
Manmade
When something harmful for mankind is done by their own and that affects the entire
environment that is called man made pollution.

3. Occurring Date:
On April 20, 2010.
Place:
Cause:
Gulf of Mexico.
An explosion on BP's Deep-water Horizon left the well gushing oil.
Impact:
11 workers killed & injured 17 others instantly. BP claimed the leak was just 1,000 barrels
per day, concealing the reality that the well was leaking anywhere from 40,000 to 162,000
barrels a day. It took 47,829 people 89 days to finally cap the well. Meanwhile, 3,500 of
workers and volunteers on the clean-up site are suffering liver and kidney damage from
their exposure to the 1.8 million gallons of toxic oil dispersant.
Ongoing or ended: It's too early to know the full extent of the environmental impact the spill had, the Gulf
fishing industry has yet to rebound, oil still washes ashore beaches along the coast, and
the surrounding coral and wetlands are a long way from recovery

4. Occurring Date:
On March 11, 2011
Place:
Cause:
In Fukushima, Japan.
A 9.0 earthquake created a tsunami that resulted in the damage of three nuclear
reactors at the Fukushima Daiichi nuclear power plant that had violated safety
requirements. This led to the only other Level 7 nuclear meltdown besides Chernobyl..
Over 100,000 were evacuated and displaced from the surrounding areas with 600
people dying during the evacuation. 300 cleanup workers received excessive exposure
to radioactive waste including 6 workers who exceeded the lifetime radiation dose limits
in the first few months after the cleanup began
Impact:
Ongoing or ended:
Geo-Location
It will be at least decades before to know all of the complications resulting from the
meltdown.

5. Occurring Date:
On December 22, 2008
Place:
In Kingston, Tennessee, USA.
Over a billion gallons of toxic sludge (a byproduct of the ash from coal
combustion ) was unleashed from the TN Valley Authority’s Fossil Plant .
Cause:
Impact:
Ongoing or ended:
Aerial View
At least 300 acres of surrounding land were affected and 15 homes
destroyed. It was the largest fly ash release in United States history.
The land is now contaminated with arsenic, mercury and lead.

6. Occurring Date:
In May 2006.
Place:
Cause:
On the island of Java in Indonesia.
Gas drilling on the earth surface .
Impact:
At least 25 people were killed by the erupted volcano instantly and more
later. Nearly 6000 people have to evacuate their residence for the eruption.
.
Ongoing or ended:
Aerial View
Hot sulfuric mud has been gushing from the ground in Sidoarjo and is
expected to expand and erupt for 30 more years.

7. Occurring Date:
Place:
In November 13, 2005
Cause:
Polluting the Songhua River with an estimated 100 tons of pollutants containing
benzene and nitrobenzene entering the water by an explosion in a chemical
plant.
Impact:
Ongoing or ended:
.
Geo-Location
Jilin City, China
At least 10,000 residents were evacuated and some were died in the
explosion.
Overcome though there are some elements of doubt of contamination in the river.

8. Occurring Date:
In between October 20 and November 6, 2007
Place:
Southern California, USA.
Cause:
18 separate fires were burning, at least one was deliberately set, while two others
were caused by downed power lines that ignited surrounding brush.
Impact:
Killed at least 10 people and forcing at least half a million more from their homes.
Ongoing or ended:
California has been ravaged by wildfires for thousands of years; they're an
essential part of the natural ecosystem. So this fire is some sort of periodical.

9. Occurring Date:
On October, 2000
Place:
West Virginia & Kentucky, USA.
Cause:
300 million gallons of coal sludge from mining operations flooded land, polluted rivers and
destroyed property in Eastern Kentucky and West Virginia.
Impact:
Massive amounts of property lose of people and destroyed everything in 100 miles of
stream all the way to the Ohio River
Ongoing or ended: Investigations were stopped short by the Bush Administration. But it is now recovered.

10. Occurring Date:
On January 30, 2000
Place:
In Romania, in the town of Baia Mare, Broke
Cause:
The water was contaminated with 55-110 tons of cyanide and other heavy metals from a
gold mine and travelled through several rivers in Romania, Hungary and Yugoslavia,
eventually reaching the Danube river
Impact:
Massive amounts of fish and aquatic plants were killed and up to 100 people were
hospitalized after eating contaminated fish..
Ongoing or ended: Still affecting the surrounding areas.

11. AL-MISHRAQ FIRE
Occurring Date:
In 2000
Place:
Near Mosul, Iraq
Cause:
Sulphur plant released 21 thousand tons of sulfur dioxide into the
atmosphere each day for nearly a month.
Impact:
Many people were hospitalized and most of the area's vegetation was
destroyed as a result.
Ongoing or ended: Still affecting the surrounding areas.

12. Occurring Date:
In 1991
Place:
Persian Gulf, near Kuwait and Iraq
Cause:
Impact:
Iraqi soldiers leaving Kuwait purposely spilled eight million barrels of oil into
the Persian Gulf to prevent a landing by the U.S. Marines.
Wildlife was damaged in the Gulf and in surrounding areas in Iraq and Kuwait
Ongoing or ended:
Still affecting the surrounding areas in some extent.

13. After analyzing the cases and more contaminations in human history we can conclude
that the main causes of pollutions are•
•
•
•
•
•
Violation of safety requirements
Release of industrial waste directly in the environment
Burning of fuel that directly releases hazardous chemicals into the air.
Direct incorporation of hazardous pollutants
By moving vehicles, man made machines and loud music
War and conflict.
