MAP20071017690Inhalation and injection experiments in rats to test the carcinogenicity of MMMF / E. Muhle... [et al.]Sumario: In parallel inhalation and intraperitoneal injection (i.p.) experiments with rats, the glass fibre JM 104, Tempstran 475, exemplifying a very thin and durable man-made mineral fibre (MMMF), was compared with crocidolite (South Africa) and chrysotile (California, Calidria RC 144). The long persistence of JM 104/475 in the lung and the carcinogenic effects of these fibres after intraperitoneal injection indicate that after inhalation of thin (< 1 microm), long and durable MMMF the suspicion of a carcinogenic potency of these fibres is still well-foundedEn: The Annals of occupational hygiene. - Oxford [etc.]. - nº 4B, 1987 ; p. 755-7641.
