为了解德阳耐火材料厂长期治理粉尘所取得的防尘效果，本文对该厂１３５名接尘工人的粉尘危害进行了动态观察（１９７４～１９９４）。结果显示，自１９７８年开始全厂粉尘平均浓度稳定在２ｍｇ／或以下，符合国家粉尘卫生标准，粉尘检测合格率１０余年来保持在８５％以上；接尘工人除呼吸系统症状和疾病（咳嗽、咳痰、慢性鼻炎、慢性咽炎等）检出率升高和肺通气功能（ＦＶＣ、ＦＥＶ１、ＭＢＣ、ＦＥＶ１％）降低外，未发现１例尘肺患者，取得了极好的社会和经济效益。
In order to understand the dust control effect of long-term treatment of dust in Deyang refractories factory, this paper carried out a dynamic observation on the dust hazards of 135 dust-exposed workers in the plant from 1974 to 1994. The results showed that the average dust concentration in the whole plant was stable at 2mg / or below since 1978, which conformed to the national dust hygiene standard. The passing rate of dust detection remained above 85% in more than 10 years. In addition to the respiratory symptoms and diseases (cough, Sputum, chronic rhinitis, chronic pharyngitis, etc.) increased detection and lung ventilation (FVC, FEV1, MBC, FEV1%) decreased, no one case of pneumoconiosis was found, and achieved excellent social and economic benefits.
