Which disease is caused by cadmium?

Itai-itai disease is caused by cadmium (Cd) exposure, produced as a result of human activities related to industrialisation, and this condition was first recognised in Japan in the 1960s. Itai-itai disease is characterised by osteomalaecia with severe bone pain and is associated with renal tubular dysfunction.

What is the disease caused by heavy metal and cadmium mainly occurring in Japan?

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. The term “itai-itai disease” was coined by locals for the severe pains (Japanese: 痛い itai) people with the condition felt in the spine and joints.

What are two of the four Big Pollution Diseases of Japan?

Severe damages from pollution Minamata Disease, Niigata-Minamata Disease, Itai-Itai Disease, and Yokkaichi Asthma are called as the four major diseases caused by pollution in Japan.

What are the main sources of cadmium poisoning?

Cadmium is a heavy metal of considerable toxicity with destructive impact on most organ systems. It is widely distributed in humans, the chief sources of contamination being cigarette smoke, welding, and contaminated food and beverages.

What are Itai-Itai and Minamata diseases?

113.4k+ views. Hint: Minamata is a neurological disease that causes ataxia, numbness in the hands and feet, and general muscle weakness including impairment of visual and auditory senses. Itai-Itai disease is a disease in which there is a severe pain felt in the spine and joints of the body.

What is Itai disease?

Itai-itai disease is the most severe form of chronic Cd poisoning caused by prolonged oral Cd ingestion. It developed in numerous inhabitants of the Jinzu River basin in Toyama Prefecture, Japan, an area most severely polluted by Cd that originated from a zinc mine located upstream.

When did Minamata disease occur?

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.). It was in May 1956, that M.

Which diseases are caused by polluted water?

Contaminated water can transmit diseases such diarrhoea, cholera, dysentery, typhoid, and polio. Contaminated drinking water is estimated to cause 485 000 diarrhoeal deaths each year. By 2025, half of the world’s population will be living in water-stressed areas.

How is Minamata disease caused?

Minamata disease is a methylmercury poisoning with neurological symptoms and caused by the daily consump- tion of large quantities of fish and shellfish that were heavily contaminated with the toxic chemical generated in chemical factories and then discharged into the sea.

Why is cadmium and mercury toxic?

Cadmium and mercury are non-biodegradable toxic metals that may cause many detrimental effects to the thyroid gland and blood. Vitamin C has been found to be a significant chain-breaking antioxidant and enzyme co-factor against metal toxicity and thus make them less available for animals.

What are the effects of cadmium?

Acute inhalation exposure (high levels over a short period of time) to cadmium can result in flu-like symptoms (chills, fever, and muscle pain) and can damage the lungs. Chronic exposure (low level over an extended period of time) can result in kidney, bone and lung disease.

Is Minamata caused by cadmium?

The main metals/metalloids responsible for the poisoning are cadmium, mercury, and lead. – The routes for entry for heavy metals in the plant, animal, and human tissues are air inhalation, diet, and manual handling. Note: – Minamata disease is known as the Chisso-Minamata disease.
