Digests from Burkina Faso (20.0 g/L) were diluted 5- to 20-fold into 1% HNO 3. Digests from Eawag (1.00 g/L) were measured undiluted. The detection limits in the liquids were 0.05 μg/L, corresponding to the detection limits in food samples of 0.05 μg/g This may explain why arsenic-induced tumors contain so many cancer stem cells. In normal tissues, stem cells are the source of replacements for damaged or dead cells.
