为了解陶瓷尘肺发病规律及X线胸片表现特征,我们于1974—1983年对该县西泉陶瓷厂的部分工人进行了尘肺动态观察。 本资料是在尘肺普查的基础上,选择单纯接触陶瓷粉尘,工龄在7年以上的42名工人作为动态观察对象。每年进行一次健康检查及摄胸片一张(12×15cm)。并定期测定主要作业环境中粉尘的浓度、分散度及游离二氧化矽含量。由原永川地区矽肺诊断组诊断确诊。 In order to understand the incidence of ceramic pneumoconiosis and X-ray findings, we carried out pneumoconiosis observations on some workers in Xiquan ceramics factory in 1974-1983. This information is based on the pneumoconiosis survey, the choice of simple contact with ceramic dust, 42 workers over 7 years of age as a dynamic observation of the object. Once a year, a health examination and a chest radiograph (12 × 15cm). And regular determination of the main operating environment dust concentration, dispersion and free silica content. Diagnosed by the original silicosis diagnosis group in Yongchuan.
