Objectives: To investigate and compare alveolar, blood, and urine concentrations of 1,3-butadiene, 2,5 dimethylfuran, and benzene, in non-occupational exposure to these products.
Methods: Benzene, 2,5-dimethylfuran and 1,3-butadiene were measured in the breath, blood, and urine samples of 61 subjects living in small mountain villages. All 61 were regularly employed as forestry workers.

A method for the determination of benzene, toluene, ethylbenzene and xylene in blood and urine of people not occupationally exposed to solvents is described. The headspace technique combined with gas chromatography with a mass spectrometer detector is used. The sensitivity of recent mass spectrometers is good enough to furnish reliable results also in biological samples collected from the general population.
