The mineral wollastonite (CaSiO 3) has the highest reaction rate with CO 2, in the range of 8.0·10 −9-2.0·10 −7 mol·m −2 ·s −1 at 25°C and in the range of 1.6·10 −5-5.0·10 −4. mol·m −2 ·s −1 at 180°C (Palandri and Kharaka, 2004; O'Connor et al., 2005). However, the availability of wollastonite is low, with global,

(2) Acceptable ceiling concentrations. An employee's exposure to a substance listed in Table Z-2 shall not exceed at any time during an 8-hour shift the acceptable ceiling concentration limit given for the substance in the table, except for a time period, and up to a concentration not exceeding the maximum duration and concentration allowed in the column under “acceptable maximum

Asbestos was considered by previous IARC Working Groups in 1972, 1976, and 1987 (IARC, 1973, 1977, 1987a). Since that time, new data have become available, these have been incorporated in the Monograph, and have been taken into consideration in the present evaluation.
