• Description:
  Nitrogen and argon isotherms were determined on amosite and on chrysotile asbestos at 2 low temperatures and in 3 states of subdividision. Surface area determinations showed that milling increased the surface area of both compounds, with amosite having a lower surface area. Argon and nitrogen isotherms showed more hysteresis with chrysotile than with amosite, thus indicating more porosity for the former. Heat of adsorption determinations showed only minor differences between the minerals. It is postulated that the delay in the removal of carcinogenic vapors from the micropores of asbestos present in the human lungs could be one explanation for the carcinogenic activity of the mineral.
