矽肺是因长期大量吸入游离二氧化硅(SiO2)粉尘(俗称矽尘)所引起的以肺组织弥漫性纤维化为主要特征的全身性疾病,是最古老、影响范围最广泛的职业病。矽肺一旦发生,呈进行性发展,不仅严重危害矽尘接触工人的健康,严重降低其劳动能力和生活质量,而且最终给国家造成巨大的经济损失 Silicosis is a systemic disease characterized by long-term massive inhalation of free silica (SiO2) dust (commonly known as silica dust) characterized by diffuse fibrosis of lung tissue and is the oldest and most widely affected occupational disease.
