| Resumen |
Results of comparative studies in animals, of medical examinations of workers exposed to carbon black, and of research on the fibrogenicity of 7 types of industrial black. A correlation was found between changes in the lungs and lymph nodes (increased weight, accumulation of lipids and of oxyproline) and the particle size of the dust. Carbon black also possesses carcinogenic properties on account of its benzo(a)pyrene content. Provided that the concentration of the latter does not exceed 35mg/kg, the threshold limit value for carbon black is of the order of 4mg/m3. |
