工业生产中工人常可接触到大量低含硅或不含硅粉尘。长期以来,由于国内外学者认为粉尘中游离二氧化硅是引起尘肺的主导病因,因而,对其它不含硅或低含硅粉尘所引起的尘肺有所忽视。许多长期接触上述粉尘的工人,常得不到应有的劳动保护和医疗救护。本文通过几种低含硅量粉尘(莹石、铝、硫化钼、煤)实验研究,探讨其致肺纤维化的可能性,观察其病理学变化特点,为提高对低含硅量粉尘所致尘肺的认识,加强肪治,提供科学根据。
Workers in industrial production often have access to a large amount of low-silica or non-silica dust. For a long time, due to the domestic and foreign scholars believe that dust in the free silica is the leading cause of pneumoconiosis, therefore, to other non-silicon or low silicon dust caused by pneumoconiosis have neglected. Many workers who have long been exposed to the dust mentioned above often do not receive due protection of labor and medical assistance. In this paper, the experimental study of several low-silicon dust (fluorite, aluminum, molybdenum sulfide, coal) to explore the possibility of pulmonary fibrosis, observe the pathological changes in the characteristics, in order to improve the low-silicon dust Pneumoconiosis understanding, strengthening the rule of the rule of law, to provide scientific basis.
