[Fiber emissions from weathered asbestos cement products. 2. Physical-chemical properties of liberated asbestos fibers].
It could be already shown that fibrous particulates can be emitted from weathered and corroded surfaces of asbestos-cement-(AC)-products and that these fibers increase the total ambient air concentration after having been dispersed in the atmosphere. In this investigation we studied the influence of the polluted atmosphere on physical and chemical properties of asbestos fibers in the corroded surface layer. It was found, that in a part of these asbestos fibers the magnesium was partly leached and that the fibers were strongly contaminated by deposited air pollutants.
