Oxidative stress induced by arsenopyrite and the role of desferrioxamine-B as radical scavenger

► Lipid peroxidation (LP) induced by FeAsS is rapid and takes place just after 10 min. ► Dissolved and structural components contribute to LP. ► The Fe3+/O2- redox system initiates LP by FeAsS. ► EPR determinations reveal that DFO-B serves as a radical scavenger.
