Via toxic exposures, it has been proven that people with MCS may develop real symptoms, such as nausea and headache, when they encounter certain odors or other toxic chemical triggers. From 2011-2016 Multiple Chemical Sensitivity was illegally added to the USA ICD10 medical diagnostic code system.
On the other hand, too much dietary selenium causes toxic effects and can lead to selenium poisoning. The threshold between essential and toxic concentrations of this element is rather narrow with a factor in the range of 10-100.
There are four main types of Keshan disease: acute, subacute, chronic, and latent. Some signs and symptoms of acute Keshan disease include dizziness, malaise, nausea, chills, loss of appetite, projectile vomiting, pallor, low arterial blood pressure (less than 80/60 mmHg), dyspnea, precardiac (anterior to the heart) or substernal (behind or below the sternum) discomfort, cardiogenic shock, and ...
Selenium deficiency occurs when an organism lacks the required levels of selenium, a critical nutrient in many species.Deficiency, although relatively rare in healthy well-nourished individuals, [1] can have significant negative results, [2] affecting the health of the heart and the nervous system; contributing to depression, anxiety, and dementia; and interfering with reproduction and gestation.
Selenium is a component of the amino acids selenocysteine and selenomethionine. In humans, selenium is a trace element nutrient that functions as cofactor for glutathione peroxidases and certain forms of thioredoxin reductase. [1] Selenium-containing proteins are produced from inorganic selenium via the intermediacy of selenophosphate (PSeO 3 3 ...
Selenium poisoning can be passed from parents to offspring through the egg, and selenium poisoning may persist for many generations. Reproduction of mallard ducks is impaired at dietary concentrations of 7 μg Se/L. Many benthic invertebrates can tolerate selenium concentrations up to 300 μg/L of selenium in their diet. [108]
