摘要
为探讨长期铸造作业对工人肺通气功能的影响 ,选择 1993～ 1999年间从事铸造作业的工人 2 18人为观察组 ,以不接触职业危害因素的生产工人 10 4名为对照组 ,每 3年进行 1次职业健康检查 ,共查 3次 ,对两组工人肺通气功能进行动态观察、比较。结果观察组肺通气功能在各年间明显低于对照组 (P <0 . 0 1) ;随接尘时间的延长 ,观察组肺通气功能 (除FEV1%外 )逐年显著下降 (P <0 . 0 5 )。提示长期从事铸造作业可对工人的肺通气功能造成明显损害。
Selected 218 founders who had took foundry work between 1993 to 1999 as the observing group,and other 104 workers who had not contacted occupational hazards as the control.Occupational physical check-up was taken every 3 years,and compared the pulmonary function between the two groups.The developments of the pulmonary function within the groups were also compared.Results showed that the pulmonary function indices in the observing group were significantly lower than the control at each year.The proportion of the actual value to the predicted of the pulmonary function indices(except FEV 1%) in the observing group was descended year by year,and there were significantly differences among all the years.It is suggested that long-time foundry work may cause obvious damage on pulmonary function of the founders.
