The biodurability of various glass fibers, rockwool, and ceramic fibers was examined in rat lungs and compared with natural mineral fibers ... Sized fractions of fibers were instilled intratracheally into Wistar rats ... The half-time of fiber elimination from the lung ranges from about 10 days for wollastonite to more than 300 days for crocidolite. The biodurability of man-made vitreous fibers (MMVF) is between these values and is dependent on the chemical composition of the fibers and the diameter and length distribution ...

Calcium silicate has been considered as a possible replacement for asbestos due to its heat and fire resistance. The cytotoxic and genotoxic potential of calcium silicate using peripheral human blood lymphocytes is described. Calcium silicates at concn of 10 and 100 ug/ml significantly increased the frequencies of chromosomal aberrations and sister chromatid exchanges. The increases in chromosomal aberrations and sister chromatid exchanges were dose-dependent, though not linearly. A significant decrease in the proliferation rate index was observed with increased dose of calcium silicates. The induction of chromatid type aberrations indicates that the clastogenic activity of calcium silicate is S-phase-dependent.
