The concentration of 0.86 mg [kg.sup.-1] (less concentration) of selenium added via diet to fry matrinxa (Bryncon orbignyanus) also did not cause any of the characteristic effects of selenosis
described in the literature (Monteiro et al., 2007).
", por ejemplo, la alusion a la Luna es evidente; y ya sabemos la connotacion, la identidad entre la mujer y esta figura luminosa--numinosa, mejor dicho--tan estudiada por Robert Graves [Cf.
Excess of selenium may cause selenosis
, selenium toxicity, however selenium deficiency is far more common and has a much greater impact on bovine agronomy than selenosis
(Zagrodzki et al., 1998).
Selenium is also known to be chronically toxic, and selenosis
has been reported both in humans and in animals.
Diagnosis and Differential Diagnosis of Chronic Selenosis
This situation, known as selenosis
, generally arises when this micronutrient's concentrations exceed 400 [micro]g per day .
Exceeding the tolerable upper intake level of 400 mg per day can lead to selenosis
More than 0.45mg a day can trigger a condition called selenosis
, which can cause brittle nails and hair, skin lesions and a garlic-like odour on the breath, added Claire Williamson, a nutrition scientist at the British Nutrition Foundation.
High Se levels in blood can result in a toxic condition called "selenosis
Selenium toxicity: a case of selenosis
caused by a nutritional supplement.
En Colombia, la selenosis
(intoxicacion natural por Se) en animales se presenta en las regiones secas de la cuenca del rio Magdalena) (45).
The levels beyond 1.5 may cause toxicity or clinical signs of selenosis
