    Symptoms of chronic bismuth toxicity in humans consists of decreased appetite, weakness, rheumatic
    pain, diarrhea, fever, metal line on the gums, foul breathe, gingivitis, and dermatitis. Jaundice and
    conjunctival hemorrhage are rare, but have been reported. Bismuth nephropathy with proteinuria may
    occur. The kidney is the site of highest concentration with the liver being considerably lower. Bismuth does
    pass into the amniotic fluid and into the fetus., Acute selenium poisoning produces central nervous system
    effects, which include nervousness, convulsions, and drowsiness. Other signs of intoxication can include
    skin eruptions, lassitude, gastrointestinal distress, teeth that are discolored or decayed, odorous ("garlic")
    breath, and partial loss of hair and nails. Chronic exposure by inhalation can produce symptoms that
    include pallor, coating of the tongue, anemia, irritation of the mucosa, lumbar pain, liver and spleen
    damage, as well as any of the other previously mentioned symptoms. Chronic contact with selenium
    compounds may cause garlic odor of breath and sweat, dermatitis, and moderate emotional instability., To
    the best of our knowledge, the chemical, physical, and toxicological properties have not been thoroughly
