关于陶瓷和瓷砖粉尘能否引起肺的粉尘性病变的文献甚少。陶粒粉尘对工人影响的问题尚未见报导。作者的调查表明,瓷砖和陶瓷土生产中主要生产性有害因素是粉尘,其浓度常常超过最高容许浓度。从化学组成看,它们属于矽酸盐。瓷砖车间粉尘中游离二氧化矽含量为23.1%,陶瓷土车间为13.1%;结合 There is little literature on whether ceramic and ceramic dust can cause dusty lesions of the lungs. The impact of ceramsite dust on workers has not been reported. The authors’ investigations indicate that the main production-hazardous factor in the production of ceramic tiles and terrazzo is dust, which concentrations often exceed the maximum allowable concentration. From the chemical composition, they belong to silicate. Tile workshop dust free silica content of 23.1%, 13.1% of the ceramic soil workshop; combined
