    Abstract:
    The study was aimed at the estimation of occupational exposure to mutagenic substances in a piston-ring foundry. The following samples were examined: solid phase of aerosol from the foundry and from different places of urban environment together with the foundry workers' urine collected during the 8-hour shift. The mutagenic substances were extracted from the collected material with acetone or concentrated with XAD-2 resin. The mutagenic property was estimated with the Ames' test using S. typhimurium strain TA98 without and with S9 fraction. The highest mutagenic activity was found at the following work-posts: caster, moulder, steerer of an induction furnace, and smelter and in the office rooms and in the flat occupied by heavy smokers. The mutagenic activity of aerosol at some other productive workposts in the foundry was similar to the mutagenic activity of aerosol in the office and flat rooms occupied by nonsmokers or in the street in Lodz. The mutagenic activity of urine from foundry workers was not correlated with the level of the occupational inhalation exposure to the mutagenic substances, however, the mutagenic activity of urine from smoking workers was about 10-20 times higher than from nonsmokers.
