Abstract

The quantitative and qualitative variations in the mixture of polycyclic aromatic hydrocarbons (PAH) present in different samples of a cutting oil, unused and after 3,6 and 9 months of use, were evaluated by means of gas-chromatography mass spectrometry. Nine of the identified hydrocarbons (phenanthrene, anthracene, fluoranthene, pyrene, benzo-a-anthracene, chrysene, triphenylene, benzo-a-pyrene, benzo-e-pyrene and perylene) were studied. The total PAH concentration increased from 45 (first sample) to 915 ng/gr of oil, even if a different behaviour for various hydrocarbons was shown. In fact some of them, such as phenanthrene and anthracene increased with use, some, such as fluoranthene and pyrene decreased and the other did not exhibit a regular trend. In the light of results, the influence of variations of the PAH mixture in oil on the PAH air concentration and on the preventive measures to be adopted, is discussed.
