Respiratory health effects of man-made vitreous (mineral) fibres.
The group of man-made mineral or vitreous fibres (MMMFs or MMVFs) includes glass wool, rock wool, slag wool, glass filaments and microfibres, and refractory ceramic fibres (RCFs). Experimental observations have provided evidence that some types of MMVF are bioactive under certain conditions. The critical role of size parameters has been demonstrated in cellular and animal experiments, when inta...

practice, the detection Ii mit of scanning electron microscopy is about 0.1 j.m (Middleton, 1982). Transmission electron microscopy may be required to detect very thin fibres (Rood & Streeter, 1985). The elemental composition of individual fibres can be determined with an energy-dispersive X-ray ana1ysis attachment combined with an electron microscope (Middleton, 1982). Fibres are counted and s...

Editorial Mesotheliomas, minerals, and man-made mineral fibres In spite of much research and frequent international meetings no clear advice can yet be given on the prevention of mesotheliomas. After the original observations of Wagner et al,' the evidence from South Africa has been consistent with t'he view that only crocidolite causes meso-thelioma. Although conditions in the African chrysoti...

induction of cancer. It is important that sufficient numbers of fibres from each sample to be tested for carcinogenicity be measured using methods that allow detection of both submicroscopie and microscopic fibres, so that the number of fibres of specific dimensional categories per unit mass can be calculated. When characterizing exposures to man-made mineraI fibres, it is necessary to specify ...
