摘　　要：目的掌握某陶瓷洁具生产企业工作场所中粉尘的职业病危害特点和对粉尘职业病危害综合治理的效果,为该行业的粉尘职业病危害治理提供经验参考。方法分析工作场所降尘的游离二氧化硅含量,分别在治理前和治理后检测原料制备、喷釉、洗改坯和修坯岗位的空气中总粉尘和呼吸性粉尘的时间加权平均浓度。结果粉尘作业场所降尘的游离二氧化硅含量的范围在22.59%～48.46%之间,治理后工作场所中的总粉尘和呼吸性粉尘浓度大幅降低(P<0.05),检测点合格率由5.4%上升到93.4%(P<0.05)。结论该陶瓷洁具厂针对粉尘职业危害的综合治理效果良好,相关措施实用有效,值得推广。[Objective]To grasp the characteristics of dust occupational hazard in the workplace and the effect of controlling dust occupational hazard in a ceramic sanitary ware production enterprise.[Methods]Content of free silica in dust of workplace was detected.Before and after controlling measure being taken,the time weighted average concentration of total dust and respiratory dust in raw material preparing workplace,spraying glaze workplace,changing and repairing billet workplace.[Results] Content range of free silica in workplace dust of the factory was from 22.59%-48.46%.After controlling measure being taken,the concentration of total dust and respiratory dust in workplaces were decreased significantly（P〈0.05）,the ratio of qualified workplace increased from 5.4% to 93.4%（P〈0.05）.[Conclusion]The effect of dust control measure in the ceramic ware factory is good.Related measures are practical and effective,and is worthy of promotion
