摘　　要：目的 了解橡胶轮胎制造厂生产性粉尘对工人健康危害的情况。方法 对某轮胎制造厂作业场所粉尘浓度进行测定，并对接尘工人178人和非接尘工人（对照组）103人进行职业性体检。结果 生产作业场所粉尘浓度平均为6．8mg／m^2，是国家卫生标准的2．3倍，粉尘分散度5μm以下占78．6％～86．1％，粉尘中游离SiO2含量5．6％。职业性健康检查中，观察组接尘工人肺纹理改变、肺功能异常、慢性鼻咽炎、胸部X线改变均比对照组工人高，差异有统计学意义（P〈0．05）。结论 橡胶行业轮胎制造厂生产性粉尘对工人健康危害大，该次调查虽然没有发现尘肺病，但是工人呼吸道的异常改变应引起有关部门的重视。[Objective] To learn the harm of productive dust on the workers＇ health in tire producing factory. [Methods] The dust concentration in the workplaces was determined; occupational physical examination was conducted on 178 dust-exposed workers and 103 non dust-exposed workers. [ Results] The dust concentration in the workplaces was 6.8mg/m3 , which was 2.3 times of the national hygienic standard; the dust dispersion degree below 5p.m occupied 40% -52% ; the dissociative SiO2 content in the dust was 5.6% ; the occupational physical examination showed that the lung texture changes, abnormal lung function, chronic rhinophar- yngitis and chest X-ray changes in the observation group were all higher than that of the control, the difference was significant （ P 〈 0.05）. [ Conclusion] The productive dust in the tire producing factory is quite harmful to the workers＇ health; although no pneu- moconiosis was detected from the examination, abnormal respiratory tract changes should be taken into consideration by relevant departments
