石棉是一系列纤维状结晶硅酸盐的统称。由于石棉纤维柔韧、可纺织、耐热(450℃以上),在工业上用途很广。但石棉细粉尘吸入人体有害于健康,故采取防尘措施非常重要。用石棉的标准样品做的实验表明,不同种类的石棉其生物学作用有明显的差异。石棉的毒性作用与纤维的长短和处理的温度有关。经研磨变成短纤维的青石棉和铁石棉对巨噬细胞的毒性大为减弱。经
Asbestos is a collective term for a series of fibrous crystalline silicates. Asbestos fiber flexible, textile, heat (450 ℃ above), in a wide range of industrial applications. Asbestos fine dust inhalation of the human body is harmful to health, it is very important to take measures to prevent dust. Experiments with asbestos standard samples show that there are significant differences in the biological roles of different types of asbestos. Asbestos toxic effects and fiber length and processing temperature. The crocidolite and asbestos fibers that have been ground into staple fibers are significantly less toxic to macrophages. through
