minamata disease is caused by pollution of water by

The ailment becomes known as “Minamata Diseases”. MINAMATA DISEASES and WATER BORNE DISEASES IN MALAYSIA Minamata Disease is a neurological syndrome caused by severe mercury poisoning. The victims of Minamata disease offer the following lessons to the world: 1. In 1969, drainage of the factory effluent containing methylmercury to Minamata Bay was regutated. Minamata disease is a methylmercury poisoning with neurological symptoms and caused by the daily consump- tion of large quantities of ・《h and shell・《h that were heavily contaminated with the toxic chemical generated in chemical factories and then discharged into the sea. In Minamata City, major industrial activities except agriculture have been depressed since the official discovery of Minamata Disease, The growth in the fish catch, commercial sales, and industrial production has become poor compared with those of the entire prefecture . Toxic water : Minamata, Japan. By 1966, the source of the pollution and the cause of the ailment were indisputable. 3. While people living outside of the Minamata area had an average level of 4ppm, people living in Mina… 1. Investigation of Cause of Minamata Disease in Two Areas 3.1. MINAMATA DISEASE VICTIMS ARE THERE? This pollution was the same as that by Chisso Corporation, Minamata, in that it was caused by an acetaldehyde factory. The fish-based diets of the people and cats of Minamata seemed to be the common thread between those showing symptoms, leading scientists to suspect the fish in Minamata Bay were being poisoned.� Minamata disease is a neurological syndrome caused by severe mercury poisoning.. Minamata disaster 1. Research on the Causative Agent of Minamata Disease in Kumamoto The epidemiological features of Minamata Disease were found to be: (1) people who ate a great deal of fish and shellfish succumbed to this Disease; (2) both men and women, In this lecture, I would like to discuss the issues of the so-called Minamata disease, which is a typical pollution-related disease caused by effluents containing mercury from chemical factories. The methylmercury targeted the central nervous system of those who ate the Bay’s polluted fish and caused numbness of the limbs, loss of bodily movement and even death. Since the presentation at the 1st meeting suggested the ingestion of large quantities of fishes and shellfishes as the cause of the disease, the consumption of fishes and shellfishes by the inhabitants decreased. There have been cases of fetal-type Minamata Disease which were caused when the mothers had been exposed to the methylmercury during pregnancy. special attention to waste water from the Chisso Minamata plant as the cause of the pollution. In 1970, the Water Pollution Control Law was enacted, which enforced control of discharge of effluent in all water areas in Japan, in relation to toxic substances, for example, mercury and cadmium. 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.). Minamata Diseases are a methylmercury poisoning disease of the central nervous system. In most cases, it is caused by water-borne bacteria, viruses and protozoans and is one of the common diseases caused by water pollution. Agricultural runoff contains dissolved salts such as nitrates, phosphates, ammoniaand other nutrients, and toxic metal ions and organic compounds. It is established that the disease differs from inorganic mercury poisoning which damages kidneys, etc., and also, it isn't confirmed that it damages organs other than nervous system. Other Asian countries are now experiencing, or are going to experience, environmental degradation including pollution as their economies develop, but the distress caused by pollution in Japan should not be repeated by its neighbors. Get this from a library! However, it caused the fishes living there to disappear entirely so the occurrence of Minamata Disease was avoided fortunately. Minamata disease was identified in Japan. Waterborne diseases are generally from human or animal waste in the water. On the other Minamata disease is a neurological syndrome sometimes known as Chisso-Minamata disease. Minamata disease is the name given to a neurological syndrome caused by or-ganic mercury intoxication. The sometimes fatal disease was the first whose cause was recognized as industrial pollution of seawater. The disease was caused when methylmercury from the chemical factory of Chisso Corporation was released into the industrial wastewater. The disease was first discovered in 1956 in Minamata, in the Kumamoto prefecture of Japan. Clinically diverse signs and symptoms are manifested; the main signs and symptoms are sensory disturbance in the distal portions of four extremities, cerebellar ataxia, bilateral concentric contr… 1959 - 1969Official government recognition On 26 September 1968, the government finally issued an official conclusion as to the cause of Minamata disease: “Minamata disease is a disease of the central nervous system, a poisoning caused by long-term consumption, in large amounts, of fish and shellfish from Minamata Bay. It manifests as a result of intestinal infection or food poisoning by drinking contaminated water with pathogens from animal or human waste. The level of mercury in the body is tested with hair samples and it is widely agreed that when these levels are higher than 50ppm (parts per million), there is likely to be nerve damage. Doctors were puzzled by her symptoms which included difficulty walking and speaking and severe convulsions. In this class, I will call this disease MPM (an abbreviation of methylmercury poisoning among people living in the Minamata area). 3. It was in May 1956, that M. d. was first officially "discovered" in Minamata City, south-west region of Japan's Kyushu Island. Waterborne diseases are caused by drinking water or eating food washed in water containing protozoa that can cause infections like toxoplasmosis or giardiasis, containing viruses like polio or Hepatitis A, water with bacteria like E.coli, cholera or typhoid fever or water with parasites like hookworm and ringworm. The first period is from the year that the first 2 patients, 2 young girls were notified to the local public health center, to the year that waste water from the causal factory was stopped (from 1956 to 1968). Backed by the national government and scientists in Tokyo, Chisso criticised researchers who blamed the disease on mercury from the factory and supported research that hunted for other potential causes, like the victim-blaming theory that Minamata residents had eaten already-spoiled fish. [Meish Goldish] -- On April 21, 1956, a five-year-old girl was examined at a hospital in Minamata, Japan. Minamata Disease is a poisoning disease that nervous system, mainly central nervous system, is damaged by methylmercury. Minamata disease is caused through the absorption of methyl mercury into the body through various environmental sources, primarily through seafood. Fertilizers contain major plant nutrients such as nitrogen, phosphorus and potassium. The pollution markedly decreased by the end of 1970s; no new cases have been reported since 1988. In 1956, the occurrence of a disease of unknown cause was reported in Minamata City. Because of its location, townspeople eat a lot of fish. Diarrhea is a disease that causes frequent and watery bowel movements. Observing cats are affected, which led to the identification of fish as the common source of food. Most commonly it results from consumption of methylmercury contaminated seafood and in severe cases is classically mani-fested by concentric constriction of the visual fields, ataxia and sensory dis-turbance in the distal extremities. Methyl mercury discharged from the factory contaminated fish and shellfish, which in turn caused illness in the local inhabitants who consumed them and birth defects in their children. Minamata disease is a disease caused by pollution, which caused methyl mercury poisoning among people who consumed seafood contaminated by methyl mercury in industrial wastewater discharged to the Shiranui Sea by Chisso Minamata Factory. Excess fertilisers may reach the groundwater by leaching or may be mix… During 1932-1968 local residents, especially fisher families have been suffering from a variety of symptoms. The four major ones in Japan are Minamata Disease, Niigata-Minamata Disease, Itai-Itai Disease and Yokkaichi Asthma.

Smith and his Japanese wife lived in the city of Minamata from 1971 to 1973 and took many photos as part of a photo essay detailing the effects of Minamata disease, which was caused by a Chisso factory discharging heavy metals into water sources around Minamata.
