作者对DQ_(12)标准石英粉尘(原样石英)及其分别吸附阳离子Ca~(++)、Zn~(++)、Al~(+++)后的细胞毒性和致纤维化做了对比实验。 DQ_(12)标准石英粉尘平均直径2μm(达5μm者不超过10%),比表面积7.4 m~2/g,游离二氧化硅含量99.1%。将原样石英置入可溶性阳离子的亚氯酸盐中3小时,阳离子即被牢固地吸附在原样石英上。用红细胞溶血实验、巨噬细胞荧光实验评价粉尘的细胞毒性。这是
The authors compared the cytotoxicity and fibrinolysis of DQ_ (12) standard quartz dust (intact quartz) and their respective adsorbed cations Ca ~ (++), Zn ~ (++) and Al ~ (+++) experiment. DQ_ (12) standard quartz dust average diameter of 2μm (up to 5μm, no more than 10%), the specific surface area of 7.4 m ~ 2 / g, free silica content of 99.1%. The original quartz was placed in the soluble cation of chlorite for 3 hours, the cation was firmly adsorbed on the original quartz. Erythrocyte hemolysis test, macrophage fluorescence test to evaluate the cytotoxicity of dust. this is
