Fig. 3From: Effectiveness of activated carbon masks in preventing anticancer drug inhalationPermeability of the masks for the vaporized CPA (n = 5). Fig. 3 indicated the permeability of the masks for the vaporized CPA. The determination in each group was repeated four times. Each bar indicated as mean ± standard □;Control (no mask), ;PCM, ;PAM, ;SAM, respectively. *** indicated a significant difference by Tukey test with less than 0.1 % of hazard ratio as compared with Control. SAM indicated below the limit of quantificationBack to article page
