Component Analysis - LD50/LC50 

Component Carcinogenicity

SELENIUM COMPOUNDS: May cause irritation and inflammation of the upper respiratory tract, redness of mucous membranes, sneezing, coughing, sore throat, metallic taste in the mouth, and gastrointestinal distress Exposure to high concentrations of fumes may cause dyspnea and possibly slight tracheobronchitis Central nervous effects may include frontal headaches, nervousness, convulsions, and death from respiratory depression Liver damage has been reported in animals following an eight hour exposure.

SELENIUM COMPOUNDS: Repeated or prolonged exposure may result in a metallic taste in the mouth followed by a garlic odor of the breath and sweat Other symptoms may include pallor, coated tongue, gastrointestinal disturbances including nausea, vomiting, abdominal pain, diarrhea, weight loss, lumbar pain, depression, lassitude, fatigue, giddiness, and emotional instability Liver and spleen effects and albuminuria, porphyrinuria, and urobilinuria have also been reported Occupational exposure of pregnant women to selenite has caused miscarriages and one bilateral club infant.

SELENIUM COMPOUNDS: Contact with selenium compounds may cause irritation, rashes and skin eruptions Some compounds are strong vesicants and can cause destruction of skin and possibly burns.

SELENIUM COMPOUNDS: Repeated or prolonged exposure to light dust concentrations of selenium compounds may cause dermatitis, paronychia, and skin eruptions Some selenium compounds are absorbed through the skin and may result in effects as detailed in chronic inhalation.
