talc 2 assessment

(2002) 46:57585. 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). Integration of evidence included consideration of consistency, coherence and the presence of exposure-response relationships. 3.2. Am J Ind Med. trailer Inhal Tox.

A 37-year update on mortality patterns in an expanded cohort of Vermont talc miners and millers. In animal studies, a statistically significant increase in lung tumors was observed after inhalation of talc, although these tumors were limited to females of one species. Overall conclusions were derived for each cancer: sufficient evidence of a causal relationship; sufficient evidence, suggestive evidence, or inadequate/insufficient evidence of an association; or suggestive evidence of no association. doi: 10.17226/11908, 9. A flow chart for the overall tiering approach used for cohort studies is provided as an example in Figure 1. Selevan SG, Dement JM, Wagoner JK, Froines JR. Mortality patterns among miners and millers on non-asbestiform talc: Preliminary report. As a powder, it absorbs moisture well and helps cut down on friction, making it useful for keeping skin dry and helping prevent rashes. We will update you as soon as the item is back in our stock. Talc is a hydrous magnesium sheet silicate (Mg3Si4O10(OH)2) with particles that are plate-like in structure. Using a lower-tier assessment approach, a small margin of exposure (MOE) of 1.5 was obtained through the comparison of the NOAEC of 2 mg/m 3 to the average In brief, selected literature pertained to talc exposure via inhalation and addressed potential associations with lung cancers or pleural mesothelioma. Additionally, the NTP (19) study involved the use of micronized talc, which has a smaller aerodynamic diameter than mined and milled talcs and talc used in talcum powder products. EPA. %%EOF Conclusion Pursuant to section 74 of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of the Environment and the Minister of Health have conducted a screening assessment of talc.

These reported results for exposure and NMRD mortality underscore the magnitude of historical exposures and consequent health risks. This can impact certain aspects of social and academic development. (1979) 73:2858. Some of the mines in upstate New York were reported to produce talcs with asbestiform or non-asbestiform amphibole minerals including tremolite and anthophyllite (42, 43, 57). In summary, lung cancer mortality was not elevated among most of the cohorts of talc miners and millers exposed to high levels of respirable talcs and accessory minerals. The pharmacokinetic data on the fate of inhaled talc indicate rapid clearance from the lung and body after single doses and no translocation of talc to other organs after single or repeated exposures. <<1A08B85A66D47145B017636F8897B5AC>]>> Get instructions and help on ordering online or from our product catalog. Historical evolution of regulatory standards for occupational and consumer exposures to industrial talc. The sample was stratified by age, gender, geographical distribution and SES using the 2001 census statistics. Berlin: Springer-Verlag (1990). 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. Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. (2017) 29:44356. Therefore, the large amount of available animal and clinical data the Panel relied on in assessing the safety of talc only. (1987() 87:22234. EPA. 5. Wehner AP, Stuart BO, Sanders CL.

We included epidemiological studies, experimental animal studies in mammalian species, and mechanistic studies in vivo or in mammalian or bacterial cell lines. This assessment presents information relevant to the safety of talc as used in cosmetic formulations. ORD Staff Handbook for Developing IRIS Assessments. Our speech and language therapists aim to work with you and your child to create a unique therapy programme that is specific to your childs difficulties, and includes their motivators and goals. A nested case-control analysis showed no association of lung cancer with increasing cumulative exposure to talc, after adjusting for smoking, exposure to quartz, and underground work (30). After eliminating duplicates or studies that were subsequently updated, and applying the inclusion and exclusion criteria determined a priori, 43 epidemiological and six animal studies remained for detailed review. 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). doi: 10.1016/0041-008X(87)90284-5, 27.

Markers of inflammation also have been observed in the lungs of rats after talc exposure, but one of the only available mechanistic studies utilized a route of exposure (i.e., intratracheal instillation) that is not comparable to inhalation exposures. doi: 10.1177/1091581815586797, 3. Narrower age bands at younger age groups were used to reflect rapid changes in grammatical understanding and reliability and validity studies were conducted. Genotoxicity studies were negative, and the few identified in vivo and in vitro mechanistic studies did not report strong evidence of the postulated chronic inflammation-mediated MOA in respiratory tissues at human-relevant exposure levels. Acta Oncol. No specific mention of mesothelioma was recorded on the death certificates. In the Vermont cohort, a single mesothelioma death was reported in the latest update; however, this case was identified through a detailed review of death certificates for the cohort (which was not performed for the reference group) in a field on the death certificate different from the conventional field for underlying cause of death (56). Historical air sampling records (i.e., total respirable dust) also were available at some locations. What will the Test of Abstract Language Comprehension assess? The original standardised version included norms of over 2,000 children and was published in 1983 with slight modifications made in 1989. Relative to cohort members with the lowest cumulative respirable dust exposure (0 to <95.1 mg/m3), individuals in the two highest cumulative exposure groups had slightly reduced lung cancer risk (RR for cumulative exposure of 95.1-<987 mg/m3 = 0.8; 95% CI: 0.31.9, and RR for cumulative exposure of 987+ mg/m3 = 0.5; 95% CI: 0.21.3).

Lung cancer mortality was slightly elevated, but did not achieve statistical significance, in the French (SMR = 1.23; 95% CI: 0.761.89) and Vermont (SMR = 1.44; 95% CI: 0.982.03) talc miners and millers but was close to unity for the Austrian (SMR = 1.06; 95% CI: 0.432.19), Italian (SMR = 1.02; 95% CI: 0.821.27) and Norwegian (SIR = 1.17; 95% CI: 0.731.79) talc miners and millers (1, 30, 53, 56). Methods for collecting and analysing respirable talc generated during the use of loose face powder and adult and baby dusting powders were established. (2007) 29:75760. Industry specifications state that cosmetic-grade talc must contain no detectable fibrous, asbestos minerals. Additional details of our methodology are provided in the Protocol in the Supplementary material, allowing verification and replication of our review. Chemically, talc is a hydrous magnesium silicate with a chemical formula of Mg 3 Si 4 O 10 (OH) 2. Talc has many uses in cosmetics and other personal care products. For example, it may be used to absorb moisture, to prevent caking, to make facial makeup opaque, or to improve the feel of a product. Exposures to talcum powder, tobacco, alcohol, and coffee.

Briefly, the cohorts ranged in size from about 400 (53) to over 1,700 (1) miners and millers that were followed for mortality for up to seven decades. There was no evidence of carcinogenic activity of talc in male or female B6C3F1 mice. WebICH Q3D Pre-Step 2 Draft Guideline Incorporates Risk Assessment, Risk Management and Risk Mitigation concepts Testing is not the default; however, where necessary Methods are outside the scope of ICH Q3D Appropriate, validated analytical methods should be used Tests should be specific for each metal (e.g. Washington, DC: U.S. Environmental Protection Agency (EPA)-Office of Chemical Safety and Pollution Prevention (2021). No use, distribution or reproduction is permitted which does not comply with these terms. In the time-course evaluation, most findings returned to control levels within 14 days. 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.

Pickrell JA, Snipes MB, Benson JM, Hanson RL, Jones RK, Carpenter RL, et al. Integrating the evidence demonstrating a lack of statistically significant increases in mesothelioma in inhalation rodent bioassays, the null findings in the higher-quality epidemiological literature, and the lack of evidence of a plausible MOA, we conclude that there is suggestive evidence of no association between inhaled talc and mesothelioma at human-relevant exposure levels.
