Analysis of toluene in exhaled air of glue sniffers and workers using thinner at work place

Toluene concentrations in exhaled air of workers using thinner at work place and glue sniffers were measured by gas chromatography (GC). Toluene concentrations in exhaled air of workers were significantly lower than those of glue sniffers. This suggests that a worker does not inhale as much thinner as a sniffer and that the analysis of thinner in exhaled air can be an indicator for its inhalation. It is also considered that the analysis of toluene concentration in the exhaled air gives an important clue whether the person inhaled thinner during working or self-abuse.
