本研究用微型计算机测力平台测量了28名下水道工人(年龄23.4~64.5岁，标准差8.7岁)的体位稳定性，以间接评估中枢神经系统的影响。所有工人都进行了四次30秒的姿势摇摆测试。有机溶剂暴露量由光电离化检测器测量。对光电离检测器进行了校准，以测量挥发性有机溶剂的总苯当量，并测量了工厂不同部位的浓度。平均暴露量为百万分之0.32苯当量(范围为0.02至0.95ppm，标准偏差为0.19ppm)。基于协变量调整的线性多元回归模型，姿势摆动和有机溶剂暴露之间存在统计学意义上的正相关(p<；0.05)。与非接触人群相比，这些工人的姿势摆动也有所增加。姿势摆动测定与有机溶剂暴露之间的统计显著相关性令人惊讶，因为所测量的暴露剂量非常低。有机溶剂接触可能不是致病因素，而是溶剂本身与其他一些致因接触有关，即总挥发性有机物与病态建筑综合征的原因有关。
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.
