作者曾在煤尘对AM毒性效应研究中发现,我国3种煤尘的细胞毒性不同,无烟煤>贫煤>肥煤。为探讨其原因,本文采用SEM/EDX和粉末X线衍射分析技术,对在原细胞实验中所使用的3种煤尘的化学元素含量及其矿物质成份进行了系统测试,探讨了煤尘矿物质成份在其毒性效应中的价值。3种煤尘游离SiO2含量甚微,且与煤尘的细胞毒性也不全一致;煤尘主要元素含量与其铝硅酸盐、硫化物、碳酸盐和硅石等矿物质成份是吻合的;各种煤尘含有不同程度的铝硅酸盐,但各自的硫化物和碳酸盐含量不同而各具特点。无烟煤中硫化物含量最高,细胞毒性最大;贫煤中硫化物和碳酸钙含量较少,细胞毒性居中;肥煤含有大量碳酸钙和氧化钙,细胞毒性最小。
The authors have found in the coal dust on the toxic effects of AM found that three kinds of coal dust in China’s cytotoxicity, anthracite> lean coal> fat coal. In order to explore the reasons, the chemical element contents and the mineral components of the three kinds of coal dusts used in the experiment of primary cells were systematically tested by SEM / EDX and powder X-ray diffraction analysis. The effects of coal dust The value of ingredients in their toxic effects. The three types of coal dust have very little free SiO2 and are not consistent with the cytotoxicity of coal dust. The main elements of coal dust are consistent with the mineral components such as aluminosilicates, sulfides, carbonates and silicas, Coal dust contains varying degrees of aluminosilicate, but each has different characteristics of sulfide and carbonate content. The anthracite has the highest sulfide content and the highest cytotoxicity. The lean coal has less sulfide and calcium carbonate and the cytotoxicity is centralized. The fat coal contains a large amount of calcium carbonate and calcium oxide with the least cytotoxicity.
