A standardized respiratory questionnaire and pulmonary function tests, including measurement of forced vital capacity (FVC), one-second forced expiratory volume (FEV1.0), and maximum expiratory flow rate at 50% FVC (MEF50%), were administered to five groups of employees in a filter-manufacturing plant to determine the acute and chronic effects of exposure to phenolic resin fumes. Employees exposed for more than five years had lower FEV1.0/FVC and MEF50%/FVC ratios than a group that had smoked more but that had never been consistently exposed to resin fumes. The existence of chronic airway obstruction was also evident by a slight excess of chronic cough and sputum production in the exposed groups. However, in spite of the high proportions of subjects reporting acute respiratory symptoms, we found only small decreased in pulmonary function during the workday and workweek.
对一家滤清器制造工厂的五组员工进行了标准化呼吸问卷和肺功能测试，包括用力肺活量（FVC）、一秒用力呼气量（FEV1.0）以及FVC为50%时的最大呼气流量（MEF50%）的测量，以确定接触酚醛树脂烟雾的急性和慢性影响。暴露超过五年的员工，其FEV1.0/FVC和MEF50%/FVC比值低于一组吸烟量更大但从未持续接触树脂烟雾的人群。暴露组慢性咳嗽和咳痰略有增多，这也表明存在慢性气道阻塞。然而，尽管有很高比例的受试者报告有急性呼吸道症状，但我们发现工作日和工作周期间肺功能仅有轻微下降。
