    Scientific Meeting of the Group of Chromatography and Related Techniques of the Spanish Royal Society of Chemistry. Barcelona (ESP), 1996/10/22.

    The volume of gasoline sold in refuelling operations and the ambient temperature, can increase significantly the environmental levels of aromatic hydrocarbon vapours and subsequently, the occupational risk of gasoline service station attendants, specially in the case of benzene.

    We have evaluated the occupational exposure to aromatic hydrocarbons by means of personal-breathing-zone samples of gasoline vapours in a service station attendant population.

    This evaluation was carried out using diffusive samplers, in two periods at quite different temperatures (March and July).

    A significant relationship between the volume of gasoline sold during the shift and the ambient concentration of benzene, toluene, and xylenes was found for each worker sampled.

    Furthermore a significant difference was found between the time-weighted average concentration of aromatic compounds measured in March, with ambient temperatures of 14-15°C and July, with temperatures of 28-30°C. In addition, 20% of the population sampled in the last period were exposed to a time-weighted average concentration of benzene above the proposed Threshold Limit Value of 960 mug/gm3 of the American Conference of Governmental Industrial Hygienists (ACGIH).
