      Chronic Toxicity or Long term Toxicity :   

                   In a two-year inhalation study of chronic toxicity and carcinogenicity using a typical toner in rats, there were no lung changes 

at all in the lowest exposure level (1 mg/m3), the most relevant level to potential human exposures. A minimal to mild degree 

of fibrosis was noted in 22% of the animals at the middle exposure level (4 mg/m3), and a mild to moderate degree of fibrosis 

was observed in 92 % of the rats at the highest exposure level (16mg/m3). The lung changes observed in the higher exposure 

groups are interpreted in term of “lung overloading”, a series of generic responses to the presence of large quantities of 

respirable, insoluble and relatively benign dusts retained for extended time periods in the lungs. Lung tumor frequency was 

unchanged among rats exposed to toner at the three exposure levels, and for air-only control rats. 

      Carcinogenicity 

                IARC Monographs: Not listed 

                NTP(USA): Not listed 

                OSHA Regulated(USA): Not listed 

                                         In 1996 the IARC reevaluated carbon black as a Group 2B carcinogen (possible human carcinogen). This 

                                        evaluation is given to Carbon Black for which there is inadequate human evidence, but sufficient animal 

                                        evidence. The latter is based upon the development of lung tumors in rats receiving chronic inhalation 

                                        exposures to free carbon black at levels that induce particle overload of the lung. 

                                        Studies performed in animal models other than rats have not demonstrated an association between carbon 

                                        black and lung tumors. Moreover, a two-year cancer bioassay using a typical toner preparation containing
