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). The relevance of the rat lung response to particle overload for human risk assessment: a workshop consensus report. The available data indicate that talc dust exposure in the modern mining of cosmetic grade talc does not appear to be injurious to health and the significantly lower dust Exposure in the normal use of cosmeticgrade talcdusts in talc-containing health and cosmetic products confirms that their use is not a hazard to health. Of three experimental animal studies of inhaled talc, only one mesothelioma was reported in a strain of rats prone to spontaneous mesothelioma.

Mortality of talc miners and millers From Val Chisone. 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. Hazard conclusions were determined using the U.S. Institute of Medicine (IOM) framework (8). Among the most recent mortality updates for the talc miner and miller cohorts (1, 30, 43, 53, 56), Honda et al. Get instructions and help on ordering online or from our product catalog. Tox Pathol.

Children start their language development through learning about concrete and fixed items, as their language develops children's understanding of certain words and concepts becomes more abstract. The authors observed increases in macrophage infiltration at 50 and 100 mg/m3 talc, but not at the lowest concentration of 5 mg/m3. 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.

Additional details of our methodology are provided in the Protocol in the Supplementary material, allowing verification and replication of our review. Talc has many uses in cosmetics and other personal care Mortality in the cohort of talc miners and millers from Val Chisone, Northern Italy: 74 years of follow-up. Drechsel DA, Barlow CA, Bare JL, Jacobs NF, Henshaw JL. We conducted a systematic review to assess the potential pulmonary carcinogenicity of inhaled talc in humans. In both rats and mice, 2-year inhalation exposure to talc was associated with chronic active inflammation and accumulation of macrophages in the lung (19). Lynch HN, Kozal JS, Russell AJ, Thompson WJ, Divis HR, Freid RD, et al. Specifically, markers of inflammation and injury were observed after intratracheal instillation of large doses of talc, exposure conditions that do not correlate with those of humans.

Each study was reviewed for relevance, and if the full text met inclusion criteria, study information was extracted into tables and the study was evaluated for reporting and methodological quality. Test only the domains of interest or test all five domains when a measure of general development is desired.. DAYC-2 was normed on a national sample of 1,832 children. Particle overload is common when high doses of poorly insoluble particles are administered particle clearance mechanisms of the lung are overwhelmed and carcinogenic processes are initiated (23, 24): see Mechanistic evidence and Mode of Action. There was no evidence of carcinogenicity in mice exposed to talc. The molecular formula for talc is Mg3Si4O10(OH)2. (2016) 38:e2016039. Identify causations- how did that happen?

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. Internal comparisons by exposure category showed that lung cancer mortality did not increase with increasing exposure for miners or millers.

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.

Similar findings were reported in rats exposed to non-asbestiform talcum powder for 6 h per day for 4 weeks via whole-body inhalation (28).

Our evaluation of reproductive tract cancers, following the same methods as the current review, to be presented in a companion manuscript (10). (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.

International Agency for Research on Cancer (2010). Study details can be found in Supplementary Table 1. Webassessment of talc. Exposure to talc aerosol produced no statistically significant differences in body weight; survival; or the type, incidence, or degree of histopathological change, relative to unexposed controls. 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 (2017) 59:65964. (2000) 12:117.

We relied most heavily on the U.S. Environmental Protection Agency's (EPA) protocol for systematic reviews conducted under the Toxic Substances Control Act (TSCA) and the Draft Handbook for the Integrated Risk Information System (IRIS) (7). We pilot tested the case-control quality evaluation for Gamble (31) and determined that its rating was equivalent to the associated cohort study (41) and thus did not separately evaluate the second case-control study. 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.

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. exposure to the perineal area from the use of certain products containing talc is a possible cause of ovarian cancer. 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 0000006564 00000 n

The authors reported a reduced exposure odds ratio (OR = 0.73; CI not reported) for cohort members in the highest cumulative talc exposure group (800 mg/m3-years). Consequently, half of the talc workers in the mortality study conducted by Dement et al. Of these, 19 epidemiology studies and three animal studies were determined to address pulmonary cancers and included in this systematic review. Pickrell et al. Wehner et al. Animal model for inhalation exposure to talc. Pickrell JA, Snipes MB, Benson JM, Hanson RL, Jones RK, Carpenter RL, et al. These reported results for exposure and NMRD mortality underscore the magnitude of historical exposures and consequent health risks.
