Casting is a technique for preparing metal products of a predetermined shape and properties. This technique involves filling with liquid metal alloys the casting moulds, which mapped the required product, eg. motor housing. Archaeological studies show that already in the Stone Age man used in his everyday life, some metallic materials - much earlier, before discovering their metallurgical properties. Castings are necessary in every area of the economy. Unfortunately, during the foundry process workers are exposed to various harmful agents, including the emission of hazardous substances. One of emission sources are foundry binders, used for production of moulding sands and cores, which at high temperature thermally decompose. Depending on the type of binder and the temperature and exposition time, can be formed compounds such as furfuryl alcohol, formaldehyde, phenol, aromatic hydrocarbons from the BTEX group (benzene, toluene, ethylbenzene, xylenes) and others. For the analysis of these compounds the most efficient technique is gas chromatography method coupled with mass spectrometry (GC/MS). The advantage of this method is, among others, its high sensitivity due to which very small samples of the analysed substances can be used – from 0,1 µl. The subject of investigations was the ecological assessment of binder based on phenol-urethane resin, where the catalyst (hardener) was an amine. This binder is used in cold-box technology to produce foundry cores.
