Scene 2 (10s)

[Audio] When And where? The Minamata disease occurred during 1932- 1968, a period of 36 years, and took place in Minamata Bay, Japan within the Kumamoto prefecture..

Scene 3 (25s)

[Audio] Incident and cause The case of the Minamata incident was a devastating disease caused by the chemical methylmercury, which was released into the water via chemical waste disposal by the Chisso Corporation. The disposal of this chemical caused the victims who consumed it, such as fishermen, to have severe mental disorder, such as stress, depression, and suicidal thoughts alongside paralysis and insanity. It especially had a huge impact on women as when they ended up consuming this chemical loss their hearing, sight, and any potential children in their womb. This incident had also caused a decrease in biodiversity, decrease in water quality, and surface water pollution. Due to this, fisherman, with many others, demanded that they were compensated at least 100,000,000 Yen, but were denied, leading to a violent riot that led to the destruction of multiple machinery. Not only were they arrested for it, the regional labor union and the citizens of Minamata sided with the Chisso company. The company was willing to pay the necessary compensations, but they, annoyingly denied legal liability, but it was resolved in a court case years later..

This all could have prevented if Egashira did not dump the waste from his facilities into the Minamata bay..

[Audio] Chemicals Used The chemical products involved in the disease were plastics and methylmercury ( II) Chloride.

Scene 8 (2m 57s)

[Audio] Chemical and Physical Properties Physical Properties: It looks crystalline in appearance and white in color. Boiling point can not be determined. Its melting point is 170 C ( 338 F). The density is 4.06 g/cm^ 3 ( 33.881 lbs/gal). Chemical Properties: flammability cannot be determined Highly toxic if inhaled, swallowed, and if it comes in contact with skin. There is no info regarding its reactivity nor its combustibility.

Scene 9 (3m 40s)

[Audio] Chemical Uses: The Chemical uses for methylmercury are synthesizing substances and to be manipulated in a laboratory. Products that methylmercury can be used are drugs, plastics, and perfumes..

Scene 10 (3m 59s)

Scene 11 (4m 23s)

[Audio] RELATION TO OUR TOPICS LEARNED IN CHEMISTRY Methylmercury is a compound, which was reviewed in class when reviewing over the units involving the states of matter and chemistry is a physical science. To add onto that, it is a heterogenous mixture, in which it is made up of 2 or more substances, which was mentioned in the units involving matter and its properties..

Scene 12 (4m 47s)

[Audio] PAST SAFETY PROTOCLS VS CURRENT SAFETY PROTOCOLS In the past it seems as if there weren't as many safety regulations considering the fact that Chisso used to dumb waste into the ocean like it was no big deal.
