Mercury oxidation in vitro by ferric compounds.
Among the ferric compounds studied, cytochrome C, methemoglobin, lactoperoxidase, ferritin and ferric ion, in addition to catalase, had the ability to oxidize metallic mercury in the presence of hydrogen peroxide. On the other hand, hematin, the active center of catalase, did not oxidize metallic mercury. The results are consistent with the increased oxidation and uptake of mercury in the liver by acatalasemia mice.
