It has been reported that some cosmetic talcs and finished talcum powders may contain trace levels of asbestiform minerals despite the lack of evidence of reliably detectable asbestos at the major sources (1). Helsinki: European Chemicals Agency (ECHA) (2021). 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). find something that cuts. Lamm et al. Inhal Tox. 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).

(2019) 61:91623. The body of epidemiological literature evaluating talc exposure and risk of malignant mesothelioma, which consists of highly exposed workers with long follow up periods, fails to demonstrate any increased risk of malignant mesothelioma. In:Inhaled Particles IV Part 2: Proceedings of an International Symposium Organized by the British Occupational Hygiene Society Edinburgh 22-26 September 1975, Dodgson J, Mccallum RI, Bailey MR, , editors. Occupational studies in which talc was known to contain asbestos are not included. This approval level enables you to buy our assessments that require no professional degree, accreditation, organization membership, or license/certificate. Pulmonary cancer (lung cancer and mesothelioma) mortality generally was ascertained via death certificates coded by certified nosologists. Beck BD, Feldman HA, Brain JD, Smith TJ, Hallock M, Gerson B, et al. 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). The primary literature search for talc exposure and all cancers was performed in PubMed (in April; updated September 2021) and yielded a total of 716 publications. In February 2016, the courts ruled in favor of the family of a woman who died of ovarian cancer at 62 years old. Env Res. 0000013312 00000 n An analysis of the National Toxicology Program's (NTP) technical report (NTP TR 421) on the toxicology and carcinogenesis studies of talc. Most of the available studies that evaluated lung cancers were rated medium quality. Quantitative Synthesis. 1322 50 (46) reported one mesothelioma (site not specified) in an electrician hired at the plant 15 years prior to his death [possibly the same case reported in (42)]. Fiume MM, Boyer I, Bergfeld WF, Belsito DV, Hill RA, Klaassen CD, et al. 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. doi: 10.1016/S0013-9351(89)80069-6, 28. However, there have been challenges with accurately identifying and quantifying asbestiform minerals in talc (2, 3). Int J Toxicol. [Unpublished]. doi: 10.1002/ajim.23106, 39. Occupation and cancer: follow-up of 15 million people in five Nordic countries. Proposed risk management objectives set quantitative or qualitative targets to be achieved by the implementation of risk management regulations, instrument(s) and/or tool(s) for a given substance or substances. Table 2. Updated Italian cohort data continues to confirm lack of mesothelioma risk in pooled cohort of international cosmetic talc miners and millers. The Chemical Abstracts Service Registry Number (CAS RN1) for talc is 14807-96-6. A speech and language therapist (frequently referred to as SALT) could carry out a full assessment using CELF which is a diagnostic tool only qualified therapists can Of three experimental animal studies of inhaled talc, only one mesothelioma was reported in a strain of rats prone to spontaneous mesothelioma. National Academies of Sciences, Engineering, and Medicine (2008). Mortality of talc miners and millers From Val Chisone. We included epidemiological studies, experimental animal studies in mammalian species, and mechanistic studies in vivo or in mammalian or bacterial cell lines.

The assessment can be used with children from the age of 2+. Lynch, H. N., Lauer, D. J, Thompson, W. J., Leleck, O. M., Freid, R. D., Collins, J., et al. I have just had a review of his statement and they are concerned about his TALC 2 results he scored level 2 and they have said he should be at level 4, They said doi: 10.1080/00039896.1967.10664815. Rubino GF, Scansetti G, Piolatto G, Romano CA. Kleinfeld and coworkers published two proportionate mortality studies on miners and millers in upstate New York potentially exposed to talc with asbestiform or non-asbestiform amphibole minerals, largely in response to reports of fibrogenic pneumoconiosis (44, 45). Questions relate to the immediate environment and require the child to think concretely e.g. 19. Although one meta-analysis (5) reported a statistically significant meta-SMR of 1.45 (95% CI: 1.221.72) for non-asbestiform talc and lung cancer, this review included several occupational cohorts with mixed exposures to possible lung carcinogens such as silica, asbestos, and radon (miners) resulting in high heterogeneity across reported study results. One peritoneal mesothelioma was reported in both studies (the same individual) and analyses including this case in the category of gastric cancers found no excess risk overall or by specific age categories (44, 45). Among the most recent mortality updates for the talc miner and miller cohorts (1, 30, 43, 53, 56), Honda et al. 18. doi: 10.1006/rtph.1995.1036, 22. Reported functions of talc in cosmetics include abrasive, The molecular formula for talc is Mg3Si4O10(OH)2.

These findings were confirmed in Ierardi et al. To comment on this thread you need to create a Mumsnet account. Kleinfeld M, Messite J, Kooyman O, Zaki MH. 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). 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). 0000018699 00000 n 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). We recognize, however, that there still may be areas where further refinement in the approach is possible. IARC. Emory TS, Maddox JC, Kradin RL. 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. Selevan SG, Dement JM, Wagoner JK, Froines JR. Mortality patterns among miners and millers of non-asbestiform talc: preliminary report. 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. of Health Education, and Welfare-Public Health Service-Center for Disease Control-National Institute for Occupational Safety and Health (NIOSH) (1980).

A 37-year update on mortality patterns in an expanded cohort of Vermont talc miners and millers. The talc powder contains 95% of hydrated magnesium silicate; associated minerals include chlorites (hydrated aluminum and magnesium silicates), magnesite (magnesium carbonate), European Food Safety Authority. 0000003272 00000 n 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). Blackshear PE, Pandiri AR, Ton TV, Clayton NP, Shockley KR, Peddada SD, et al. (56) reported that the death certificate for the single mesothelioma death in the cohort explicitly mentioned exposure to asbestos; yet no additional information was available regarding this potential exposure (56). A comprehensive literature search was conducted. Additional searches in Web of Science identified no additional publications. 0000059323 00000 n Animal model for inhalation exposure to talc. Between 6% and 8% of the inhaled dose was deposited in alveoli. This approval level enables you to buy all our assessments.

By 132 days after exposure, there were no statistically significant differences in talc burden in the lungs of exposed vs. unexposed hamsters, indicating clearance of the particles. Registration Dossier: Talc (Mg3H2(Si03)4). A cohort mortality and nested case-control study of French and Austrian talc workers. As noted above, the talcs produced from these mines have been reported not to contain asbestiform minerals and testing has not produced reliably detectable levels of asbestos of any fiber type [e.g., regarding the Italian mines, see (1)]. Wild P, Leodolter K, Refregier M, Schmidt H, Zidek T, Haidinger G, et al. (30) reported no increased lung cancer mortality among French (SMR = 1.23; 95% CI: 0.761.89) and Austrian (SMR = 1.06; 95% CI: 0.432.19) talc mining and processing employees (30). Table 1. Lines are open from9am to 5pmMonday to Friday(excluding bank holidays). 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).
