New detoxification processes for asbestos fibers in the environment
…Val Malenco fibers into non-fibrous debris. Chrysotile's crystal and spectral signatures disappeared, and magnesium oxalate was the only crystalline reaction product detected, apart from reactor steel debris. Treated Balangero fibers still showed serpentine features…

Potential toxicity of nonregulated asbestiform minerals: balangeroite from the western Alps. Part 3: Depletion of antioxidant defenses
…crocidolite incubation. This effect was not related to any increased content of oxidized glutathione, or to any enhanced efflux of glutathione, suggesting that balangeroite fibers, like crocidolite, might favor the reaction of GSH with other molecules.

In vitro cleavage by asbestos fibers of the fifth component of human complement through free-radical generation and kallikrein activation
…role in inflammatory reactions characteristic of asbestosis through mechanisms involving iron ions, hydroxyl radicals, and oxidized C5-ike fragments. The ferrous ions present at the asbestos fiber surface trigger this activation and catalyze, via Fenton reaction…

Surface reactivity and cell responses to chrysotile asbestos nanofibers
…Alps. Electron microscopy, X-ray diffraction, and fluorescence spectroscopy revealed that the procedure does not affect mineralogical and chemical composition. Surface reactions related to oxidative stress, free radical generation, bioavailability of iron, and antioxidant depletion, revealed…
