The Chemical Abstracts Service Registry Number (CAS RN1) for talc is 14807-96-6. 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 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). Lung tumors occurred at very high administered doses that appeared to cause particle overload and using micronized talc (not typical of talc mining or milling exposures, or of cosmetic talcum powder products), limiting the ability to extrapolate these findings to relevant exposures in humans. There was one lung carcinoma found in the group exposed to talc for 3 min/day for 30 days, and one lung carcinoma found in the 300-day control group.

Oxford: Pergamon Press (1977). Based on the quality evaluation methods, domains and quality criteria (described above and detailed for all studies in Supplementary Tables 5, 6), most of the studies assessing pulmonary cancer risk among talc miners and millers were rated medium quality.

Occupation and mesothelioma in Sweden: updated incidence in men and women in the 27 years after the asbestos ban. Although these studies overall were considered to be of high quality, there were some important deficiencies that limited their utility, which are discussed below. Findings for each of the cohort studies that was rated high quality for exposure characterization are discussed more below. 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. 0000004445 00000 n This substance is among those substances identified as priorities for National Academies of Sciences, Engineering, and Medicine (2008).

Internal comparisons by exposure category showed that lung cancer mortality did not increase with increasing exposure for miners or millers. No epidemiological studies were identified that assessed consumer use of talc and talcum powder products. 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. (2009) 48:646790. 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. ECHA. Our search identified six studies assessing talc exposure and tumor formation in animal models. The conclusions we reached in this systematic review are similar to those of IARC. Occupational exposure to talc increases the risk of lung cancer: A meta-analysis of occupational cohort studies. Blank suggests 4 levels for questioning starting from concrete questions relating to the here and now to more abstract questions that requires higher level thinking and knowledge and experience. A few studies provide evidence of some key events in the proposed inflammatory MOA; however, data are limited to non-human relevant exposure pathways and/or cell-based assays. Table 1.

Direct-reading approaches were valuable for providing detailed characterization of short duration exposures to airborne talc particles, and will be useful to support future exposure assessments of talc and other powders in consumer products. The pulmonary toxicity of talc and granite dust as estimated from an in vivo hamster bioassay. When considered together, the moderate confidence in study findings, large study populations, long duration of follow up, and consistency of null findings indicate that talc exposure is not associated with mesothelioma.

The SMRs for the eligible cohorts ranged from 0.92 in a Norwegian cohort [] to 4.50 in a Chinese 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. The molecular weight is 379.3 g/mole. 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).

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).

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). (1979) 2:27384. J Occup Med. Two adenomas (not considered cancerous) were observed in talc-exposed animals, 13 lung tumors were found in chrysotile-exposed animals, and one adenoma occurred in the air-exposed control group. 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.

Albumin, a marker of pulmonary edema, also was increased. 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)]. 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).

Most of the available studies that evaluated lung cancers were rated medium quality. Evidence was synthesized across all epidemiological studies and then integrated with animal study findings and mechanistic considerations to reach conclusions for human pulmonary cancers.
