The objective of this study was to investigate if the dust in a mill producing soft paper tissue caused respiratory symptoms or impaired respiratory function. Using a questionnaire and spirometry, 355 persons were examined. They were divided into three groups according to present exposure to dust; low (less than 1 mg/m3), moderate (1-5 mg/m3) and heavy (greater than 5 mg/m3). There was a dose-dependent increase of symptoms from the upper respiratory tract. However, coughing and coughing with phlegm were not found to be more common among persons with heavy exposure compared to those with low exposure to the dust. There was no difference in FEV1 or FVC during a work shift. Persons with long-term (greater than 10 years) and heavy exposure to dust seemed to have impaired respiratory function compared to those with low and/or short-term exposure to the dust.
本研究的目的是调查生产软质纸巾的工厂中的粉尘是否会引起呼吸道症状或损害呼吸功能。通过问卷调查和肺活量测定法，对355人进行了检查。根据目前接触粉尘的情况，他们被分为三组：低暴露组（低于1毫克/立方米）、中度暴露组（1 - 5毫克/立方米）和高暴露组（高于5毫克/立方米）。上呼吸道症状呈剂量依赖性增加。然而，与低粉尘暴露者相比，高粉尘暴露者咳嗽和咳痰的情况并未更常见。在一个工作班次期间，第一秒用力呼气容积（FEV1）或用力肺活量（FVC）没有差异。与低粉尘暴露和/或短期粉尘暴露者相比，长期（超过10年）高粉尘暴露者的呼吸功能似乎受到了损害。
