What is selenium toxicity?
The toxicity of selenium, also called selenosis, concerns a condition in which the animal has too many trace minerals of selenium in its body. In terms of people, a small amount of selenium is required for optimal health. It combines with proteins and helps to create antioxidants, regulate some thyroid functions and healthy functioning of the immune system. The complete understanding of selenium toxicity involves knowledge of how animals gain selenium and health risks associated with too large selenium.
selenium can be found in the soil because it is a trace mineral. Plants are a primary source of selenium and the amount of selenium found in them depends on the levels of selenium in the soil where they grow. Animals get selenium through their diet by eating plants and grasses rich in selenium or consuming meat from animals that ate ate -rich plants. In the human diet, some of the most foods rich in selenium, ton and beef.
Daily recommended selenium intake ranges from 15 to 55 micrograms per day depending on age. Infants under 6 months should have about 15 micrograms a day, while those who are 7 months under 3 years should have approximately 20 micrograms a day. Children from 4 to 8 years may have 30 micrograms a day and 9 to 13 years should have 40 micrograms. People aged 14 and over have a recommended daily selenium intake of 55 micrograms, while women are pregnant and breastfeeding requiring another 10 to 15 micrograms a day.
If too much selenium is ingested, more than 400 micrograms per day are usually toxic to adults. The most common symptoms associated with selenium toxicity are garlic breath, nausea, hair loss, white spotted nails, hair loss, irritability and slight nerve damage. The death caused by the toxicity of the selenium HAVE was rare, but serious symptoms include diarrhea, excess salivation and shallow breathing. The deaths that occurred as a result of selenosis were industrial nEnOdy.
The toxicity of selenium, especially to the level that causes death, usually occurs in livestocks that graze in areas that have a high amount of selenium in the soil. Midwest United States has the highest level of selenium in the soil. China has small or no selenium in its land and other areas of the world, such as Africa, Russia and South America, and also has a low level.
