  • The effect of fibre size on the in vitro biological

    Three standard (UICC) samples of amphibole asbestos were subjected to ball-milling the main effect of this procedure was to reduce the length of the fibres present in each sample. The numbers of fibres in unit masses and the distribution of fibre sizes in all the samples both parent and milled were estimated from electron micrographs.
