Iron associated with asbestos bodies is responsible for the formation of single strand breaks in phi X174 RFI DNA
…iron was responsible. Amosite fibres (5000 fibres/reaction), with a similar length distribution to that of the asbestos bodies, did not catalyse detectable amounts of single strand breaks in DNA under identical reaction conditions. The results…

Pathologic changes in the small airways of the guinea pig after amosite asbestos exposure
… where these fibers penetrated the airway walls, an interstitial inflammatory and fibrotic reaction (asbestosis) occurred. It is concluded that 1) amosite asbestos produces diffuse abnormalities throughout the noncartilagenous airways and possibly the cartilagenous airways as well…
