Biological evaluation of the aggressiveness of dust formed during the manufacture of carbon electrodes in the carbon electrode plant.

The biological aggressiveness of five dusts formed during the production of carbon electrodes was evaluated using intraperitoneal, pulmonary and hemolytic tests. The greatest increase in the hydroxyproline level in the lungs of the experimental animals was observed in the group that had been administered dust from the Moulding Shop. Dusts from the Carbon Electrode Plant in Raciborz exhibit weak fibrogenic properties.
