Geography GCSE is not a requirement but is helpful.
This IB will work well with Biology A level/IB, Geography A Level, animal care/management courses, business courses (as businesses are looking to become much more sustainable).
Slide4Topic 2 Ecosystems:
Bioaccumulation
The following task will demonstrate a real life case of bioaccumulation that we know as
Minamata
disease.You will be given a series of ‘clues’, after each one you will make an educated guess as to the cause of
Minamata
disease.
Slide5I
n
the 1950s
more
than 900 people were killed.
An
estimated 2 million people from the area suffered health problems or were left permanently disabled.
Minamata
Bay is a coastal town on the Japanese island of Kyushu
1
Slide6Minamata
is a fishing port
.
2
Slide7The
people
there, like most Japanese people, eat a diet primarily
of fish and shellfish
.
3
Slide8The
Chisso
corporation had a big factory in
Minamata
. From 1945 onwards it was making lots of
acetylaldehyde
used for plastic.
Mercury is a
byproduct
of this process
4
Slide9Around
1952 cats
in the fishing port began
to exhibit bizarre
behaviour, the
effects were severe
enough that they came to
be named as having “dancing cat
fever”
that sometimes resulted in their falling into the bay and dying, in what residents referred to as "cat suicides."
5
Slide10On April 21, 1956, a five year- old girl was examined at a hospital in
Minamata
.
She had puzzling symptoms: difficulty walking, difficulty speaking and convulsions
They soon found other family members and local children with the same symptoms
6
Slide11More and more people were showing symptoms. They
would stumble
whilst
walking, not be able to
write,
have trouble hearing or swallowing, or tremble uncontrollably.
In 1956 an apparent epidemic broke out and one can imagine the confusion--and fear--that was prevalent because no one knew the cause
.
7
Slide12The factory was dumping its waste water which flows into the Bay which the locals fish from
8
Slide13The Answer: Mercury poisoning!
Mercury from
the
Chisso
plant
was released in the waste water which was absorbed by the fish and shellfish in the Bay. Cats were eating the fish scraps from the fishermen and mercury built up in their bodies first.
The locals, eating the fish and shellfish from the bay, had mercury building up in their bodies until it became toxic
Slide14The humans and cats eat many fish so get a larger concentration.
Cats have small bodies and are
a
ffected first.
Then children and finally adults show signs
Bioaccumulation
.
T
he fish absorb a small amount of mercury, not enough to affect them.

Deep water horizon. What does this have to do with the topic of Water?
The
Deepwater Horizon oil spill was an industrial disaster that began on April 20, 2010, in the Gulf of Mexico
operated by BP and
considered to be the largest marine oil spill in the history of the petroleum industry.SO WHAT?
Slide17Water pollution, both to groundwater and surface water, is a major global problem, the effects of which influence human and other biological systems.

Slide19What can we do?
Studying Environmental science will enable you to pursue a career that will help save the environment and encourage people to live sustainably.
Aaron did just that and has never looked back…
