在系统检索国外近十多年来尘肺研究文献基础上,深入地调研了煤工尘肺病因学研究的新进展,从而对70年代以来的发展趋势和水平有了基本了解。概括地说,70年代是煤的“品位”说或煤的“地质层位”说占主导,而进入80年代则是煤的“超分子结构”说和“自由基”说取得了突破性进展。以往人们认为,粉尘的致纤维化作用主要表现于与接尘量、粉尘成分以及分散度的依从关系。进入70年代后,人们注意到煤工尘肺的流行情况与严重程度是同煤的地质
Based on the literature of pneumoconiosis retrieval in the past 10 years in foreign countries, we have made a deep research on the new progress of the etiology of pneumoconiosis in coal workers, and have a basic understanding of the development trend and level since the 1970s. In a nutshell, the “grade” of coal in the 1970s or the “geologic horizon” of coal dominated the talk of the “supramolecular structure” of coal and the breakthrough of “free radicals” in the 1980s . In the past people think that the cause of dust fibrosis is mainly reflected in the amount of dust, dust composition and dispersion compliance. Into the 70’s, people noticed the prevalence and severity of coal workers pneumoconiosis is the same geological coal
