Fig. 6From: Difference in carcinogenicities of two different vapor grown carbon fibers with different physicochemical characteristics induced by intratracheal instillation in ratsCorrelation between surface area at total doses and the incidence of the malignant mesothelioma. The total dose of 0.128, 0.64, 3.2 mg/kg were a surface area of 0.0032, 0.016, and 0.08 m2/kg for MWNT-7, a surface area of 0.00192, 0.0096, and 0.048 m2/kg for VGCF™-HBack to article page
