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.

Studies on the role of oxygen radicals in asbestos-induced cytopathology of cultured human lung mesothelial cells
…after exposure to amosite asbestos, although oxygen radicals were readily detected in cells exposed to menadione, an uncoupler of oxidation-reduction reactions. Cellular thiol levels were reduced after exposure to menadione, but were not affected by…

Comparative pulmonary responses to inhaled inorganic fibers with asbestos and fiberglass
…rats and hamsters but not in guinea pigs. Fine fiberglass particles were not fibrogenic. Rats revealed more fibrogenic pulmonary reactions than guinea pigs or hamsters. A few pulmonary tumors developed in animals exposed to asbestos, Fybex…
