abstract：:The pathogenicity of mixed dust from a fluorite mine was studied by animal experiments and in vitro tests. Animal experiments showed that calcium fluorite can induce only a foreign body reaction in the lungs; the fibrous nodular lesions induced by the fluorite mine dust are due mainly to its silica component. It was d...
