尘肺是矿工长期吸入空气中的生产性有害物质而引起的以肺脏病变为主的全身性疾病。 引起尘肺的原因和井下空气中的浮游粉尘浓度,游离二氧化硅含量以及吸入时间的长短等因素有着密切的联系。其中最直接最重要的原因是粉尘中游离二氧化硅(矽)的含量,含量越高,致病力越强。因为游离的二氧化硅(矽)对人体具有毒性作用,能使 Pneumoconiosis is a systemic disease mainly caused by lung lesions that is caused by the long-term inhalation of minerals by manufacturing workers in the air. The cause of pneumoconiosis is closely related to the concentration of suspended dust in the air, the content of free silica and the length of inhalation time. One of the most direct and most important reason is the content of free silica (silicon) in the dust, the higher the content, the stronger the pathogenicity. Because free silica (silicon) on the human body has a toxic effect, can make
