  1. Postural stability assessment in sewer workers.

    Article - En anglais

    In this study, postural stability was measured with a microcomputer-based force platform as an indirect assessment of central nervous system effect in 28 sewer workers (age range 23.4 to 64.5 years, standard deviation of 8.7 years).

    All workers performed four 30-second postural sway tests.

    The organic-solvent exposure was measured by a photo-ionization detector.

    The photo-ionization detector was calibrated to measure volatile organic solvents in total benzene equivalence, and concentrations were measured in various parts of the plant.

    The mean exposure was. 32 parts per million (ppm) benzene equivalent (range of. 02 to. 95 ppm, standard deviation. 19 ppm).

    Based on a covariate adjusted linear multiple-regression model, a statistically significant (p<. 05) positive correlation was demonstrated between postural sway and organic-solvent exposure.

    These workers also had increased postural sway compared with a nonexposed population.

    The statistically significant correlation between postural sway determinations and organic-solvent exposure was surprising given the very low exposures measured.

    It is possible that the organic-solvent exposure might not be the causative agent, but rather that the solvents themselves correlate with some other causative exposure, ie, total volatile organics as implicated in the cause of sick-building syndrome.
