虽然人们都认为石英和其它形式的二氧化硅可使多种动物产生进行性纤维化,形成纤维结节,最后玻璃样变,但煤矿工尘肺的病因学问题仍需进一步研究。必须注意到矿尘中石英含量很低,其它粉尘成分可能抑制石英尘的致纤维化作用。此 Although quartz and other forms of silica are thought to cause progressive fibrosis in a variety of animals, forming fibrous nodules and finally glassy transformation, the etiology of coal miners’ pneumoconiosis still needs further study. It must be noted that quartz dust in mine dust is low, and other dust components may inhibit the fibrinization of quartz dust. this
