A woman ingested 400 ml of leather tanning solution containing 48 g of
basic chromium sulphate (CrOHSO4). This substance forms hydrogen ions
and trivalent chromium when it reacts with tissue proteins. The patie
nt died of cardiogenic shock, complicated by pancreatitis and gut muco
sal necrosis and haemorrhage. There are no reported cases of toxicity
due to oral ingestion of trivalent chromium. Toxicity of hexavalent an
d trivalent chromium is dicussed and suggestions made for management o
f future cases.
