Itai-itai disease (イタイイタイ病, itai-itai byō, "it hurts-it hurts disease") was the name given to the mass cadmium poisoning of Toyama Prefecture, Japan, starting around 1912.

What is the cause of Minamata disease and itai-itai disease?
Minamata and Itai Itai disease are due to the toxicity of mercury and cadmium respectively. The Minamata disease which is also known as Chisso-Minamata disease is caused by severe mercury poisoning which can lead to insanity, paralysis, coma, and even death within weeks after the first symptoms are seen.
When did itai-itai disease start?
Itai-itai disease was officially recognized in 1968 as the first disease induced by environmental pollution in Japan after legal proceedings. The basis of the court decision is simply but clearly shown in "The view of the Ministry of Health and Welfare" which consisted of 7 articles and was announced on 8th May, 1968.
What is Etai Etai?

Which of the following metal is responsible for Minamata disease?
Minamata disease (M. d.) is methylmercury (MeHg) poisoning that occurred in humans who ingested fish and shellfish contaminated by MeHg discharged in waste water from a chemical plant (Chisso Co. Ltd.).
Where was the painful bone disease Itai-Itai reported first?
Itai-itai disease is a well-known health hazard induced by cadmium (Cd) that was first reported in the Cd-polluted Jinzu River basin of Toyama Prefecture, Japan.
Which metal is responsible for disease?
The heavy metals most commonly associated with poisoning of humans are lead, mercury, arsenic and cadmium. Heavy metal poisoning may occur as a result of industrial exposure, air or water pollution, foods, medicines, improperly coated food containers, or the ingestion of lead-based paints.
What is cadmium used for?
Common industrial uses for cadmium today are in batteries, alloys, coatings (electroplating), solar cells, plastic stabilizers, and pigments. Cadmium is also used in nuclear reactors where it acts as a neutron absorber.
What products is cadmium found in?
Cadmium is used in many products, including batteries, pigments, metal coatings, and plastics, and it is found in cigarette smoke. Cadmium enters the environment through mining operations and the action of wind and rain. Forest fires and volcanoes also release some cadmium to the air.
What was the teratogen that caused Minamata disease?
Disease, Minamata: A disorder caused by methyl mercury poisoning that was first described in the inhabitants of Minamata Bay, Japan. Minamata disease resulted from their eating fish contaminated with mercury industrial waste.
How many people died from the Itai-Itai disease?
1–3 As of 28 December 1999, 410 patients were officially diagnosed or suspected of having Itai-itai disease. 4 Since then, 380 patients have died of the condition; 85 of these patients underwent autopsies performed in Toyama University Hospital.
What makes cadmium toxic?
Ingested cadmium is usually stored in the liver, kidneys, and bones. Eliminating cadmium absorption naturally is a slow process, and cadmium can last for decades in the human body. One of the main causes of cadmium toxicity in the United States is cigarette smoke.
How is cadmium formed?
Thus, cadmium is produced mainly as a byproduct of mining, smelting, and refining sulfidic ores of zinc, and, to a lesser degree, lead and copper. Small amounts of cadmium, about 10% of consumption, are produced from secondary sources, mainly from dust generated by recycling iron and steel scrap.
What Colour is cadmium?
Cadmium is a moderately soft, silvery white metal with a melting point of just over 700 degrees Celsius. Cadmium compounds have been used as a source of colour since the discovery of cadmium in 1817 by the German chemist Friedrich Stromeyer.
Who named cadmium?
Much like its southern neighbor on the periodic table, mercury, cadmium has a relatively low melting point for a metal – 321°C (610°F). Cadmium was discovered in 1817 by German chemist Friedrich Stromeyer.
Which metal causes harmful effect?
Because of their high degree of toxicity, arsenic, cadmium, chromium, lead, and mercury rank among the priority metals that are of public health significance. These metallic elements are considered systemic toxicants that are known to induce multiple organ damage, even at lower levels of exposure.
Is copper a heavy metal?
The most commonly found heavy metals in waste water include arsenic, cadmium, chromium, copper, lead, nickel, and zinc, all of which cause risks for human health and the environment (Lambert et al., 2000). Heavy metals enter the surroundings by natural means and through human activities.
Is nickel a heavy metal?
Nickel, a known heavy metal is found at very low levels in the environment. ... In the environment, nickel is principally bound with oxygen or sulfur and forms oxides or sulfides in earth crust. The vast industrial use of nickel during its production, recycling and disposal has led to widespread environmental pollution.
Which of the following ion is responsible for Minamata disease?
Minamata disease was caused by the release of methyl mercury in the industrial wastewater from a chemical factory, where it bioaccumulated in aquatic food chains reaching its highest concentrations in shellfish and fish which, when eaten by the local population, resulted in mercury poisoning.
What is the cause of Minamata disease Class 10?
Complete answer: - Minamata disease is a severe neurological disease caused due to mercury poisoning. It is caused due to the consumption of fish that were once living in mercury-poisoned water.
What is mercury formula?
Cite. Mercury is a chemical element with symbol Hg and atomic number 80.
Is mercury toxic?
Mercury may have toxic effects on the nervous, digestive and immune systems, and on lungs, kidneys, skin and eyes. Mercury is considered by WHO as one of the top ten chemicals or groups of chemicals of major public health concern.
Is arsenic toxic?
Exposure to high enough amounts of arsenic can be fatal. Exposure to lower levels of arsenic over longer periods of time can cause skin changes, liver and kidney damage, and a shortage of red and white blood cells, which can lead to fatigue and an increased risk of infections.
