The latter can affect gastrointestinal absorption rates. Other reported signs and symptoms of acute selenosis include tachycardia, nausea, vomiting, abdominal pain, abnormal liver function, muscle aches and pains, irritability, chills, and tremors. In humans, inhalation of selenium or selenium compounds primarily affects the respiratory system. Information on toxicity of selenium in humans and animals following chronic inhalation exposures is not available, and subchronic and chronic inhalation Reference Concentrations have not been derived. Epidemiologic studies in humans havation between chronic oral exposures to selenium and an increased incidence of death due to neoplasms.
Quantitative data are, however, insufficient to derive a slope factor for selenium sulfide.
Pertinent data regarding the potential carcinogenicity of selenium by the inhalation route in humans or animals were not located in the available literature.
