Pneumoconiosis in carbon black workers.

Pneumoconiosis is a chronic inflammatory and fibrotic lung disease caused by the inhalation of many substances in various forms, of which carbon black is one of them. Workers exposure may occur during production, collection and handling of the substance as well as in many other ways. Most reports describe the effect of carbon black on the lung of human's certain changes which are typical for pneumoconiosis and changes that are suspected to become pneumoconiosis in the future. There were many studies describing carbon black pneumoconiosis from 1951 to 1994. This disease, therefore, has been considered as an occupational disease of workers exposed to carbon black in its production and usage.
