A study of workers exposed to asbestiform minerals in commercial talc manufacture

Asbestos in commercial cosmetic talcum powder as a cause of mesothelioma in women

“…2 Previous research suggests that ovarian cancer and peritoneal mesothelioma may be directly attributed to the use of talcum powder contaminated with asbestos or from exposure to partners occupationally exposed to asbestos. [3][4][5][6][7] Using talcum powder in closed spaces may increase the likelihood of inhaling the powder laced with asbestos. Repeated applications increase the opportunities for inhalation and the asbestos could become concentrated in the peripheral airways and alveoli of the lungs of the talcum powder users.…”

Malignant pericardial mesotheliomas and asbestos exposure: A case report

“…Case 3 involved exposure to talc. There have been numerous publications about the occurrence of asbestos contained in talc [Blejer and Arlon, 1973;Hildick-Smith, 1976;Kleinfeld et al, 1973;Luckewicz, 19751. In the GDR, talc is considered among the group of asbestos-containing materials, unless there is evidence by a mineralogic phase analysis that no asbestos is present.…”

Occupational exposure to talc containing asbestos: morbidity, mortality, and environmental studies of miners and millers.

“…Comparisons between present dust (mppcf) and fiber (fibers > 5-~m in length/cc) exposures and historic exposure me~surements are shown in Tables 11 and 12, respectively. These data are gathered from a number of sources (11,(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33).…”

“…The company stated that talcs extracted from its original mine in the Gouverneur Talc District do not contain asbestiform minerals and that the talcs have been so certified (13). One study, however, at the same operations concluded that asbestiform minerals were contained in the talcs (11). To address this contradiction, the present study restricts itself to that one mine and mill reported by the company to be producing nonasbestiform talc.…”

“…Previous studies by Kleinfeld et al (5,6) of asbestiform talc miners and millers in this district have demonstrated significantly increased proportional mortality due to both malignant and nonmalignant respiratory diseases. Morbidity studies also have indicated increased symptoms and X-ray and lung function changes consistent with pneumoconiosis (7,8,9,10,11,12). More 1 recently a talc mlnlng company in this district maintained that these studies were not applicable to all talcs in the Gouverneur Talc District.…”
