Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Results and discussion

Details on results:
Incubation of iron with isolated rat liver nuclei stimulated fragmentation of single-stranded DNA, incorporation of [3H]thymidine into DNA and the binding of 59Fe to DNA. FeCl2 was about twice as active as FeCl3. Lipid peroxidation took place in nuclei incubated with FeCl2, but not with FeCl3. Generation of reactive forms of oxygen was required for iron-mediated DNA damage, but evidence for direct interaction of reactive oxygen with DNA was not found. Apparent adducts of iron bound to DNA seemed to be formed by an enzymic mechanism.
