Fenton Reaction
…around them in the lung) to chronic oxidative damage and carcinogenesis. Significance in Asbestos Context The Fenton Reaction is one of the leading biological mechanisms used to explain how asbestos fibers cause cancer at the cellular…

Decarbonation
…of asbestos, decarbonation reactions during metamorphism of carbonate-bearing rocks can produce the magnesium-rich silicate minerals from which asbestos fibers grow. Origin The term comes from the Latin prefix de- (removal) and carbonate, reflecting the…

Redox Cycling
Redox cycling is a repeating chemical reaction in which iron (or another metal) on the surface of an asbestos fiber alternates between two oxidation states, generating harmful reactive oxygen species such as hydroxyl radicals with each…

Erythema
…It is a clinical sign, not a disease, and can result from inflammation, infection, allergic reaction, radiation, heat, or drug effects. Origin The term comes from the Greek 'erythēma,' meaning a flush or redness, from 'erythros'…

Fenton Chemistry
…ferrous iron catalyzes the oxidation of organic molecules by hydrogen peroxide. The reaction was later recognized as a central mechanism of biological oxidative stress. Significance in Asbestos Context Asbestos fibers, especially amphiboles like crocidolite and amosite…

Biologically Active Iron
…Ann Aust, and others, who showed that iron on asbestos fiber surfaces catalyzes the Fenton reaction, producing hydroxyl radicals that damage DNA and cell membranes. The term reflects the distinction between total iron content and the…

Mixed-Valence Iron
…fibers, this coexistence of iron states is chemically important because it allows the fiber surface to drive reactions that generate harmful reactive oxygen species inside the body. Origin The concept comes from inorganic and mineral chemistry…
