(43) extended follow-up of this cohort from 1948 through 1989, reporting two deaths from pleural mesothelioma; however, the underlying causes of death on the death certificates officially were coded by the New York State nosologists as benign neoplasm of the respiratory system and malignant neoplasm of bronchus and lung, unspecified, respectively.

We also identified several meta-analyses/pooled studies, two large cancer registry-based linkage studies examining cancer risks by occupational group but lacking specific information on individual exposures (32, 33), and several talc pleurodesis studies (3437). In:Dusts and Disease, Lemen R., Dement J.M, , editors. what should we do now? It has been concluded that there was an inadequate evidence of carcinogenicity in experimental animals and the degree of evidence in short-term tests for genetic activity has been found to be inadequate. Considering the totality of the evidence, we conclude that there is suggestive evidence of no association between inhaled talc and lung cancer at human-relevant exposure levels. Although two of the studies reported no increase in tumor formation among talc-exposed animals (15, 17, 18, 20), NTP (19) reported a higher incidence of lung tumors in female rats in the highest exposure group, relative to controls.

This study aims to compare and analyze the environmental performance of Miscanthus biochar-reinforced polypropylene (MBPP) and talc-reinforced polypropylene (talcPP) composites for automotive parts and determine whether the replacement of the later with the former composite is advantageous from an environmental perspective. 56. Brigham and Women's Hospital, Harvard Medical School, United States. Animals were exposed to 0, 6, or 18 mg/m3 talc for 6 h/day for 5 days/week until death or until the mortality of any exposure group reached 80% (approximately 2 years). In sum, and based on the integration of evidence from animal experiments, mechanistic evaluations, and epidemiological studies all of reasonable methodological quality, it is unlikely that talc and cosmetic talcum powders at human-relevant exposures cause human pulmonary cancers, including lung cancer and mesothelioma.

Therefore, the body of literature eligible for full review consisted of studies evaluating workers occupationally exposed to high levels of talc during mining and milling operations. 7. Because the case-control studies were nested within cohorts, we did not expect substantive differences in quality. Our search identified six studies assessing talc exposure and tumor formation in animal models. Talc and mesothelioma: mineral fiber analysis of 65 cases with clinicopathological correlation. Mortality from lung cancer was slightly lower than expected for the entire cohort. There is no credible evidence of a cancer risk from inhalation of cosmetic talc by humans from retrospective epidemiological, statistically barely significant case-control studies of questionable biological import, and convincing scientific documentation is shown. The sample was stratified by age, gender, geographical distribution and SES using the 2001 census statistics. In:Dusts and Disease, Lemen R, Dement JM, , editors. The objective of this paper was to apply systematic review methods to critically evaluate and synthesize the scientific evidence addressing the possible relationship(s) between exposure to talc occupationally and from exposure to talc-containing products (primarily talcum powders and cosmetics) and pulmonary cancers, specifically lung cancer and pleural mesothelioma, integrating epidemiology, toxicology, and studies informing potential underlying modes of action. We included epidemiological studies, experimental animal studies in mammalian species, and mechanistic studies in vivo or in mammalian or bacterial cell lines.
