Study of volatile noxious compounds composition during the use of lubricant-coolant fluids.

The aim of the study was the gas chromatography (GC) separation and mass spectrometric (MS) identification of volatile compounds mixture generating in the air of work environment when lubricant-coolant fluids (LCFs) are used. GC/MS method was used for determining mixture ingredients. Hydrocarbons, carbonil compounds, esters, oxiranes and aromatic amines were identified in test samples. When LCFs are used, monitoring of highly toxic substances (aromatic amines, carbonil compounds and oxiranes) makes the assessment of risk and exposure more complete.
