Question

Minamata is caused due to the pollution of-
a. Organic waste into drinking water
b. Oil spill in water
c. Industrial waste mercury/Methylmercury into in fishing water
d. Arsenic into the atmosphere

Answer 1

Hint: Minamata disease sometimes called Chisso-Minamata disease, is a neurological condition caused by stern mercury poisoning. Symptoms include ataxia, deadness in the hands and feet, general muscle fault, narrowing of the meadow of vision, and injury to hearing and speech. In extreme cases, lunacy, paralysis, unconsciousness, and death follow within weeks of the beginning of symptoms.

Complete answer:
The discharge of mercury or methylmercury from the industries into the drinking water bodies and the succeeding consumption of the water fallout in the neurological disease called Minamata disease. It was first observed in 1956 from the Kumamoto prefecture, Japan. The signs of the poisoning include ataxia, lack of sensation in the hands and feet, muscle failing, tapering of the field of vision, and damage to audible range and speech.

Much of the arsenic in the ambiance comes from high-temperature practices such as coal-fired power plants, burning foliage, and volcanic activity.

Oil spills constitute about 12% of the oil that enters the ocean. Oil spills cause a much-localized problem but can be catastrophic to confined marine wildlife.

The Minamata Convention on Mercury is the worldwide treaty that was signed in 2013 to guard the human population against the unfavorable effects caused by the discharge of mercury.

Hence, the accurate answer is 'Industrial waste mercury/ Methylmercury into fishing water'
So, the correct answer is option (B).

Additional information:
This disease was caused by the liberation of methylmercury in the industrial wastewater from the Chisso Corporation's chemical factory, which was retained from 1932 to 1968.

Note: This highly lethal chemical bio-accumulated in shellfish and fish in Minamata Bay and the Shiranui Sea, which once consumed by the local general public leads to mercury poisoning. While cats, dogs, pigs, and human deaths last over more than 30 years, the administration and corporation did little to avert the pollution.
