Ninety-eight Brisbane waterside workers who had been exposed to several dusts, particularly that of asbestos fibre, were studied. Forty-nine subjects complained of dyspnoea while walking uphill, 46 had basal endinspiratory crepitations, and chest X-ray films showed small irregular opacities in 41 subjects and pleural abnormalities in 27 subjects. Internal comparisons showed that ventilatory function was correlated significantly with duration of employment on the wharves, independently of the effect of age and total cigarette consumption. Forced vital capacity decreased by 20 mL/year on wharves, and one-second forced expiratory volume by 34 mL/year, in excess of the age-related decrease. These findings suggest that these workers have developed parenchymal lung disease probably related to asbestos-dust exposure on the wharves.
对98名接触过多种粉尘，尤其是石棉纤维粉尘的布里斯班水边工人进行了研究。49名研究对象称上坡行走时会出现呼吸困难，46人有吸气末基底啰音，胸部X光片显示，41名研究对象有小的不规则阴影，27名研究对象有胸膜异常。内部比较显示，通气功能与在码头的工作时长显著相关，与年龄和总吸烟量的影响无关。在码头工作时，用力肺活量每年下降20毫升，一秒用力呼气量每年下降34毫升，超过了与年龄相关的下降幅度。这些发现表明，这些工人可能因在码头接触石棉粉尘而患上了实质性肺部疾病。
