What Is a Selenium Toxicity?

Selenium poisoning is caused by people eating foods and water with high selenium content, or engaging in some work that is often exposed to selenium, which can occur to varying degrees. Animals can also be poisoned when they consume high selenium-containing pastures or other selenium-rich feeds. In acute poisoning, a syndrome called "staggering blindness" occurs. It is characterized by blindness, abdominal pain, salivation, and finally death from dyspnea due to muscle paralysis. In chronic poisoning, hair loss, hoof removal, angular deformation, long bone joint erosion, stiff limbs, lameness, heart atrophy, cirrhosis, and anemia are known as "livestock selenium poisoning or alkali disease. ^[1]

Selenium poisoning

Selenium poisoning is caused by human consumption

Selenium is an essential trace element in the body. Insufficient or excessive intake of selenium may cause disease. element

Selenium is an essential trace mineral nutrient for the human body. It exists mostly in oxidation state (Se, Se, and Se).

In China's high-selenium coal-bearing strata, the leaching and migration of selenium has been accelerated due to warm, humid and rainy weather; and the local villagers have the habit of using stone coal fire soil as the bottom fertilizer, causing serious soil damage

Endemic selenium poisoning generally has a chronic course. According to the clinical symptoms, endemic selenium poisoning can be divided into two types:

1. Blind Toddler: This is due to humans and animals

1. Living in high-selenium areas for a long time, eating food or poultry meat with high selenium content.

2. Clinical manifestations.

3 High blood selenium.

The treatment of selenium poisoning is mainly to reduce or eliminate the toxicity of selenium. Acute and acute illness caused by ingestion of foods high in selenium (containing 15 mg of selenium)

The most effective way to prevent selenium poisoning is to prevent humans and animals from consuming selenium-rich foods and feeds. The United States has adopted methods to remove selenium-rich pastures or change pastures to prevent it. Some livestock also have the ability to identify selenium-rich pastures, as some selenium-rich pastures emit a garlic odor.

In addition, the sulfur content in the soil can inhibit the absorption of selenium by plants. Therefore, some countries have adopted grassland applications.

Selenium is a chemical element. Myocardial degeneration and necrosis "Keshan disease" was prevalent in areas lacking selenium in China, but almost disappeared 30 years ago. Selenium has appeared in the health field, and has been promoted to have anti-cancer and anti-cancer effects. Various selenium supplements have been flooding the market. However, scientists have not found that selenium supplementation can prevent cancer, but reminded that excessive intake of selenium may cause poisoning. ^[3]
