Organic degradation and emission products from painted steel were studied in laboratory experiments. Steel plates coated with paints for the ship building industry were heated with a liquid gas flame to 350°C. Emitted products were collected by different adsorption tubes, bubbler absorbers, and filters, for identification by gas chromatography, liquid chromatography, and mass spectrometry. The main degradation products typically originated from the binders in the paints, i.e., bisphenol-A from epoxies, phthalic anhydride from alkyds, butyraldehyde from polyvinylbutyral. Small molecular aldehydes, acids, and solvents were also detected. For sampling on-site an XAD-2 tube with a pre-connected glass fiber filter and a chemosorbent tube for aldehydes is recommended.
