Radical oxidation reactions of the purine moiety of 2'-deoxyribonucleosides and DNA by iron-containing minerals
…was investigated by using a double experimental approach. One involved the electron spin resonance spin-trapping measurement of organic radicals obtained by the reaction of activated oxygen species, released upon incubation of the minerals in phosphate…

Microsomal lipid peroxidation and oxy-radicals formation are induced by insoluble iron-containing minerals
…two processes are mainly due to the presence of redox active iron at the surface of the solid particles and thus are greatly inhibited by desferrioxamine, a strong iron chelator. However, these reactions are not correlated.
