【摘要】 本文选择了均属烟煤的大同煤矿和汾西煤矿为研究对象。比较了两矿煤肺的患病率,并取煤尘进行溶血试验,细胞毒性实验及大鼠染尘实验,均表明大同煤较汾西煤的致纤维化作用强。大同媒中多种金属元素(Ni、Pb、Cu、Co)及挥发份均非常显著地高于汾西煤。为此将两种煤去掉挥发份后,再进行实验,结果表明,处理后的两种煤均较未处理的煤对细胞的毒性减低。认为挥发份在煤尘致纤维化作用中有一定影响,但并不是唯一的因素。更多还原

【Abstract】 The soft coal of Datong and Fenxi Coal Mines were studied and the incidence of paeumoconiosis ia these two coal mines were compared. Hymolytic tests, cytotoxity tests and dust exposure tests in rats showed that the fibrogenesis of Datong coal was stronger than that of Fenxi coal. The trace metal elements (Ni, Pb, Cu, Co,) and volatile matter content of Datong coal were significantly higher than those of Fenxi coal. After elimination of the volatile matter in these two coals, experiments showed that their cytotoxities were reduced. These results suggest that volatile matter in coal may affect the fibrogenesis of coal dust to some degree, but that volatile matter is not the only factor affecting fibrogenesis.更多还原
