摘要
[目的]了解水泥粉尘对从业人员鼻和咽部疾病发病的影响。[方法]调查1a产20万tR型硅酸盐水泥厂,统计分析3a粉尘监测资料,对960名水泥生产工人与非接尘组进行体验,对比分析名水泥生产工人鼻和咽部疾病的发病情况。[结果]接触水泥尘的人员比不接触水泥尘的工人鼻和咽部疾病发病率高(P<0.005),其中接触生料尘比熟料尘者更甚(P<0.005)。工龄对发病无明显影响(P>0.05)。[结论]建议采取有效收尘除尘。加强个人防护及劳动保护知识教育,以综合措施控制水泥粉尘对从业人员的危害。
[Objective] To study the effect of concrete dust on the morbidity of nose and throat diseases among workers. [Method] Analyze 3 - year dust supervision information in a R type silicate concrete factory which annually produces 200.000 t of concrete. 960 workers in this factory undertook physical examination and were compared with a contrast group. [Result] Those workers who were exposed with concrete dust has a higher morbidity rate of nose and throat diseases ( P < 0.005) . Among them, those who are exposed with raw material dust have more chance of morbidity than those exposed with processed material dust ( P < 0.005) . Working years has no significant influence on the morbidity ( P < 0.05) . [ Conclusion] Good dust absorbing and cleansing methods are suggested to be taken. Personal protection and labor protection education should be widespread in order to control the damages of concrete dust on workers.
