ACUTE TOXICITY



   LD50

   Oral

   Rat

   5000 mg/kg



   LD50

   Oral

   10000 mg/kg



SIGNS AND SYMPTOMS OF EXPOSURE

   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. Damage to the kidneys. Damage

   to the liver. To the best of our knowledge, the chemical,

   physical, and toxicological properties have not been thoroughly

   investigated.



ROUTE OF EXPOSURE
