TL;DR: A 22-month-old infant died after ingesting sodium dichromate his father had brought from work and supportive care, forced diuresis, and chelating agents may be helpful, and Hemodialysis may be required if renal failure occurs.
Abstract: A 22-month-old infant died after ingesting sodium dichromate his father had brought from work. Treatment included folic acid and dimercaprol administration, hemodialysis, and exchange transfusion. To evaluate this treatment, four dogs were hemodialyzed after receiving intravenous sodium dichromate: their dialyzer chromate clearance was similar to their renal chromate clearance and their dialyzer chromate clearance was not sibmificantly different before or after dimercaprol administration. This and other cases in the literature indicate that although chromate poisoning is often fatal, supportive care, forced diuresis, and chelating agents may be helpful. Hernodialysis may be required if renal failure occurs. Awareness of toxicity and prevention remain the most important approaches.

TL;DR: Rat preparations were totally inactive and trout preparations were slightly active in producing mutagenic metabolites from benzo(a)pyrene (BP), but rat homogenates were significantly more efficient in activating aflatoxin B1 (AFB1) and, in particular, 2-aminofluorene (2-AF).

TL;DR: In this paper, an electrodeposited composite film of chromium and magnesium on the roughened surface of copper foil was used to manufacture copper foil with superior heat resistance and rust preventiveness.
Abstract: PURPOSE:To manufacture copper foil with superior heat resistance and rust preventiveness used in a wiring plate for a printed circuit by forming an electrodeposited composite film of chromium and magnesium on the roughened surface of copper foil. CONSTITUTION:Using the face of copper foil laminating on the side of a circuit as a cathode the surface of the foil is roughened in a copper sulfate plating bath with an electric current exceeding limiting current density. An electrolytic bath contg. 1-10g/l sodium dichromate, 1-20g/lmagnesium sulfate and 1-20g/l sodium solfate is adjusted to current density to form a composite thin film of chromium and magnesium on the foil. A water soluble sexivalent chromium compound such as chromium trioxide may be used in place of the dichromate, and the magnesium sulfate may be replaced with other water soluble magnesium salt.
