本文对 4 9例市政清洁工人的呼吸系统损害情况进行了调查。结果表明 ,市政清洁工人所有慢性呼吸道症状发生率显著高于对照组 ,且工龄越长 ,发生率越高 ;肺功能各项指标也明显降低 ,以实测值 /预计值 <80 %为异常 ,用力肺活量 (FVC)和一秒用力呼气容积 (FEV1.0 )异常率最高。经检验清洁工组与对照组间存在显著性差异 ,因此认为 :反映清洁工人肺功能损害的敏感指标是FVC和FEV1.0 。
This article investigated the respiratory system impairment of 49 municipal cleaners. The results showed that the incidence of all chronic respiratory symptoms of municipal cleaners was significantly higher than that of the control group, and the longer the length of service, the higher the incidence; the indexes of pulmonary function were also significantly reduced. The measured / predicted value <80% was abnormal FVC and one second forced expiratory volume (FEV1.0) the highest rate of abnormalities. After checking the cleaning group and the control group there are significant differences, so that: reflect the cleaning workers lung function damage sensitive indicators are FVC and FEV1.0.
