Toxicity
ToxicityBody Burden
A patient with scalp lesions and that used selenium shampoos had a level of selenium sulfide as high as 32 ug/mL in her urine(1).
Soil Adsorption / Mobility
Selenium sulfide does not readily dissolve in water and would probably bind tightly to the soil(1).
Artificial Pollution Sources
... In 1976, EPA estimated that the medicinal industry generates about 700 pounds of selenium sulfide wastes annually.
Probable Routes of Human Exposure
NIOSH (NOES Survey 1981-1983) has statistically estimated that 2,965 workers (2,490 of these were female) were potentially exposed to selenium sulfide in the US(1).
Symptoms
No documented reports of serious toxicity in humans resulting from acute ingestion of selenium sulfide, however, acute toxicity studies in animals suggest that ingestion of large amounts could result in potential human toxicity. (L1522)
Treatment
Evacuation of the stomach contents should be considered in cases of acute oral ingestion. (L1712)
Toxicity Data
LD50: 138 mg/kg (Oral, Rat) (T59)
Health Effects
Chronic oral exposure to high concentrations of selenium compounds can produce a disease called selenosis. The major signs of selenosis are hair loss, nail brittleness, and neurological abnormalities (such as numbness and other odd sensations in the extremities). Animal studies have shown that selenium may also affect sperm production and the female reproductive cycle. (L619)
Adverse Effects
NTP Carcinogen - Reasonably anticipated to be a human carcinogen.
Exposure Routes
Oral (L619); Inhalation (L619); Dermal (L619) There is no substantial absorption through intact skin. Absorption has been reported in patients with open lesions on the scalp or in patients using a 1% cream on the back - a patient with scalp lesions that used selenium shampoos had a level of selenium sulfide as high as 32 μg/ml in her urine.
Toxicity Summary
Selenium sulfide can be decomposed to selenium ions. Selenium readily substitutes for sulfur in biomolecules and in many biochemical reactions, especially when the concentration of selenium is high and the concentration of sulfur is low. Inactivation of the sulfhydryl enzymes necessary for oxidative reactions in cellular respiration, through effects on mitochondrial and microsomal electron transport, might contribute to acute selenium toxicity. Selenomethionine (a common organic selenium compound) also appears to randomly substitute for methionine in protein synthesis. This substitution may affect the structure and functionability of the protein, for example, by altering disulfide bridges. Inorganic forms of selenium appear to react with tissue thiols by redox catalysis, resulting in fo...
