测定了鳞石英、α—这石英和硅胶以及它们和卵磷脂作用的表面(电位,研究了它们对家兔肺泡巨噬细胞的毒性作用。结果表明:二氧化硅的表面)电位越高,与卵磷脂等肺表面活性物质作用越强,因而致硅肺作用越强烈。毒性作用顺序为:鳞石英>α—石英>硅胶。
The tidal quartz, α-quartz and silica gel and their interaction with lecithin (potentials were studied for their toxic effects on rabbit alveolar macrophages. The results showed that the higher the surface potential of silica, Lecithin and other pulmonary surfactant more strongly, resulting in the stronger the role of silicosis. Toxicity order: tridymite> α-quartz> silica gel.
