Abstract
Condensable effluents from the thermal decomposition of a typical green sand foundry mold were investigated for the presence of emissions that could present health hazards in a foundry atmosphere. The benzene-soluble fraction extracted from the condensate was analyzed by gas chromatography/mass spectrometry. Over 200 compounds were observed on the chromatograms and benzo(a)pyrene, benzo(e)pyrene and perylene were identified. The concentrations of these materials were not determined, but their presence in foundry atmospheres represents in area of potential concern for health welfare.
