[Research progress of refractory ceramic fiber's damage to human respiratory system]

Refractory ceramic fibers (RCFs) , as the main substitute for asbestos, are widely used because of their high temperature resistance and good thermal insulation. In the air of its production and use places, RCFs are inhalable fibers that are easy to deposit in the lungs. The results of a number of epidemiological studies and a variety of toxicological methods have shown that RCFs are related to the occurrence of lung diseases. This article reviews the four aspects of RCFs-induced pleural thickening, pulmonary fibrosis, lung function damage, tumor and genetic damage, and looks forward to the prospects of RCFs on respiratory system damage related research.
