Resumen |
Besides known acute effects in case of fires, there are various occupational situations where polyurethanes are subjected to decomposing temperatures (cutting or welding, additives in foundry sands) giving rise to intermittent exposure. The aerosol fraction of the oxidative thermal decomposition products (700°C) of rigid polyurethane foam was collected on glass fiber filters and fractionated into ether-soluble neutral, acidic, and basic constituents and water-soluble compounds. The constituents showed mutagenic activity in a bacterial fluctuation test with Salmonella typhimurium TA 98 or Escherichia coli CM 891 as the tester strains. Several primary aromatic amines were detected in the aerosol, but no polycylic aromatic hydrocarbons. |
