Talc was negative for mutagenicity and other forms of genotoxicity in all available assays, described in brief below. hbbd```b``"CA$Cd"f@n]$},H5? 'c Some of the popular cosmetic ingredients discussed in this paper may exert a negative influence on human health, and many of these harmful effects have been discovered recently. Industry specifications state that cosmetic-grade talc must contain no detectable fibrous, asbestos minerals. Integrating all streams of evidence according to the IOM framework yielded classifications of suggestive evidence of no association between inhaled talc and lung cancer and pleural mesothelioma at human-relevant exposure levels. Washington, DC: The National Academies Press. Three case series (3840) drawn from medico-legal consultation practices were identified, but these did not meet the inclusion criteria for epidemiological studies (e.g., because they lack referent or control groups) and thus were not selected for further review. Washington, D.C.: Office of Chemical Safety and Pollution Prevention-U.S. Environmental Protection Agency (EPA) (2018). Occupational studies in which talc was known to contain asbestos are not included. 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. Therefore, the large amount of available animal and clinical data the Panel relied on in assessing the safety of talc only. Talc was also negative in a companion host-mediated mutagenicity assay using male ICR mice injected with Salmonella typhimurium and Saccharomyces cerevisiae, with and without metabolic activation (16). 0000004445 00000 n doi: 10.1097/JOM.0000000000000992, 52.

Download HL4() Mp3 Courtesy in from Top Song with 0 and 1 & 03:41 just only in beta.ustaflorida.com 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. doi: 10.1006/rtph.1996.1076, 15. The body of epidemiological evidence is reasonably large and robust for lung cancer and mesothelioma and provides the most weight in the evidence integration, complemented by the number of high-quality experimental animal carcinogenicity bioassays, as well as the lack of convincing mechanistic evidence. The EFSA Panel on Food Additives and Nutrient Sources added to Food provides a scientific opinion reevaluating the safety of calcium silicate, magnesium silicate and talc when used as food additives, finding that there is no mechanistic rationale for a group ADI for silicates and silicon dioxide and the groupADI established by the SCF is obsolete.

In contrast to the lack of excess lung cancer deaths among talc miners and millers, a strong and consistent association has been observed between occupational talc exposure and non-malignant respiratory disease (NMRD), including pneumoconiosis (30, 43, 49, 56). Lung cancer risk did not increase with increasing cumulative exposure categories after adjustment for age and years since hire (43). As a result, the validity and relevance of these findings remains unclear; however, the epidemiological studies reflect potential risks associated with exposures to talcs including whatever accessory minerals and contaminants that might be present. Historical air sampling records were used to estimate cumulative dust exposure for each worker.

Gamble JF. Draft Systematic Review Protocol Supporting TSCA Risk Evaluations for Chemical Substances Version 1.0: A Generic TSCA Systematic Review Protocol with Chemical-Specific Methodologies. Cause-specific mortality and cancer morbidity in 390 male workers exposed to high purity talc: A six-decade follow-up. This assessment presents information relevant to the safety of talc as used in cosmetic formulations. These findings were confirmed in Ierardi et al. Although the paucity of mechanistic information remains a limitation, the balance of evidence, especially the volume of epidemiological evidence demonstrating no increased cancer risks associated with even the highest real world human-relevant exposures, strengthens the current analysis. #EPA-D-20-031. We conducted a systematic review to assess the potential pulmonary carcinogenicity of inhaled talc in humans. A three-fold excess of mortality due to NMRD was reported in the earliest cohort study of New York talc workers, reflecting the high concentrations of dust present in the workplace; prior to 1948, median exposures ranged from 61 to 1,196 mppcf (45). Historical air sampling records (i.e., total respirable dust) also were available at some locations. Generally, lung talc burdens of mice exposed to 18 mg/m3 were disproportionately greater than those of mice exposed to 6 mg/m3, suggesting clearance of talc from the lung was impaired in mice exposed to 18 mg/m3. Numerous validity studies, including studies of the tests sensitivity and specificity, are provided. There was a single occurrence of malignant mesothelioma in a high-dose male rat; however, aging F344 rats have been reported to develop spontaneous mesotheliomas (22). p. 370. doi: 10.1007/978-3-642-75124-0_32, 26. Klimisch HJ, Andreae M, Tillmann U. In one study, Syrian golden hamsters were administered a single, 2-h, nose-only exposure to commercial baby powder (MMAD of 6.46.9 m) (15, 16). The Italian, Norwegian, French, and Austrian talc mines all produced talcs described as non-asbestiform with various accessory minerals including small amounts of chlorite and quartz (30, 50, 52). While this does not affect the quality of the study, as discussed below, micronized talc is not used in cosmetic talcum powder products and may limit the study's generalizability for assessing risk associated with the use of cosmetic talcum powder. 631 0 obj <>/Filter/FlateDecode/ID[<166AC119B1656D9BFB80A0EC76A47BBB><33215A8A902138498BC011EEBA38DDC5>]/Index[620 27]/Info 619 0 R/Length 78/Prev 882784/Root 621 0 R/Size 647/Type/XRef/W[1 3 1]>>stream Outcome assessment for these studies typically encompassed a full histological examination or autopsy; clinical and body weight monitoring was also conducted in two of the studies (15, 18, 19). Training, advice, support and strategies for parents, teachers and other professionals. This exposure assessment focuses on routes of exposure where critical effects have been identified; namely, non-cancer lung effects following inhalation of insoluble respirable particles of talc, and an association with ovarian cancer following perineal exposure to talc. Overall, in available animal studies, there is indeterminate evidence that talc is associated with lung tumors in rodents based on negative findings in several high-quality studies and species, but positive results in a single species and sex (female rats) exposed to high doses of micronized talc that caused particle overload conditions. 41. doi: 10.1097/00043764-197603000-00013, 51.

Six historical talcum powders were evaluated using modern-era analytical methods to determine if asbestos is present, and if so, to identify the mineral habit ( asbestiform versus non-asbestiform) of the asbestos. Talc concentrations of 10.8 mg/m3 were administered for 7.5 h per day, 5 days per week; 48 animals from each group were exposed for 3 months, 24 animals for 6 months, and 24 animals for 12 months with cumulative doses of approximately 4,100, 8,200, and 16,400 mg/m3-h for the 3-month, 6-month, and 12-month exposure durations, respectively. Among 705 white men employed between 1957 and 1977, lung cancer mortality was statistically significantly elevated among workers employed < 1 year (SMR = 3.17, based on six lung cancer deaths).

WebThe greatest ovarian cancer risk associated with perineal talc use was observed in the subgroup of women estimated to have made more than 10,000 applications during years when they were ovulating and had an intact genital tract (OR 2.8, 95% CI 1.4-5.4); however, this exposure was found in only 14% of the women with ovarian cancer. Inhal Toxicol. The National Toxicology Program (19) exposed F344/N rats and B6C3F1 mice to air or micronized Pfizer MP 1052 talc via whole-body inhalation. Given the moderate confidence in study quality ratings and the lack of a consistent association between occupational talc exposure and lung cancer mortality, the available epidemiological evidence does not demonstrate a causal association between talc exposure and lung cancer mortality. However, the lung tumors occurred only in female rats exposed at a dose also inducing significant chronic lung toxicity and high lung talc burden, such that the maximum tolerable dose may have been exceeded (21). In an in vivo OECD Guideline 478 Dominant lethal test, male Sprague-Dawley rats were exposed via gavage to a single dose or one dose/day for 5 days of 300, 3,000, or 5,000 mg/kg talc. Further, some aspects of the physiology and function of the respiratory system of rodents (e.g., a delicate balance of pulmonary surfactants, as well as smaller and fewer macrophages relative to humans) make them highly susceptible to high doses of solid particles relative to humans (29).

While some cohort mortality studies reported an association between occupational talc exposure and lung cancer mortality, additional epidemiological investigations reported no such association or attributed observed increased risks to potential confounding by cigarette smoking, as risks did not correlate with indicators of talc exposure (4347). Of three experimental animal studies of inhaled talc, only one mesothelioma was reported in a strain of rats prone to spontaneous mesothelioma. Albumin, a marker of pulmonary edema, also was increased. We employed qualitative and hierarchical or tiered approaches to arrive at the overall study quality score, tailored to each study type and outcome. The proposed risk management objective for talc is to decrease inhalation and p When stratified by employment history, talc workers with known prior employment also showed excess lung cancer mortality (SMR = 2.14; no CI reported), and talc workers with no known work prior to their talc facility employment showed a slight deficit of lung cancer deaths (SMR = 0.76; no CI reported). Three studies (30, 43, 50) were rated high quality for the exposure characterization domain. An additional 10 epidemiological studies were identified through supplemental searches using narrower terms (e.g., lung cancer, mesothelioma, millers, miners) and considering the tertiary literature (reviews, gray literature).
