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). WebThe TROG-2 is a fully revised and nationally re-standardised version of the widely used TROG. Note that this route of administration (intratracheal instillation) produces different lung distribution patterns compared to inhalation, which limits its relevance to inhalation exposures to talc in humans. Methods used to derive cause of death were poorly described, and included a variety of sources including death certificates, employment records, and hospital records, resulting in a low quality rating for that domain, and low overall quality rating (44, 45).

No specific mention of mesothelioma was recorded on the death certificates. 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).

Similarly, in the latest update of the Italian cohort, excess mortality for pneumoconiosis (SMR = 9.55; 7.4312.1) was observed among talc miners and millers (1). #EPA-D-20-031.

Park Forest South, IL: Pathotox Publishers, Inc (1979). Because the case-control studies were nested within cohorts, we did not expect substantive differences in quality. Am J Ind Med. 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. One strength of our review is that we drew from the strongest aspects of established methodologies of several organizations' systematic review guidance in an attempt to provide a full and transparent evaluation. 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. (2022). Reg Tox Pharm. Brussels: European Centre for Ecotoxicology and Toxicology of Chemicals (ECETOC) (2013). 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.

Wergeland E, Andersen A, Baerheim A. Morbidity and mortality in talc-exposed workers. As with other particles, one postulated carcinogenic MOA for talc is chronic inflammation resulting from the overwhelming of particle clearance mechanisms (i.e., phagocytosis), long-term tissue irritation and release of inflammatory chemokines and cytokines, and reactive oxygen species (ROS) formation.

Although some of the individual cohorts were small, the collective number of workers followed was substantial (6) and the cohorts were followed for many decades. 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). A brief overview of the quality evaluation results is presented below, followed by a summary of study findings. doi: 10.17226/11908, 9. Study details can be found in Supplementary Table 1. 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. Coggiola et al. 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). Thorax.

Histologic evaluation of lung tissue revealed no exposure-related lesions except for a modest, diffuse increase in free macrophages within alveolar spaces of both rats and mice exposed to the highest concentration of talc. Talc has many uses in cosmetics and other personal care Park Forest South, IL: Pathotox Publishers, Inc (1979). Detailed data abstraction and study quality evaluation, adapting the US Toxic Substances Control Act (TSCA) framework, were central to our analysis. May, 2018. Findings for each of the cohort studies that was rated high quality for exposure characterization are discussed more below. Talc is a naturally occurring mineral. 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.

Application of Systematic Review in TSCA Risk Evaluations. 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. 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. doi: 10.1006/rtph.1996.1076, 15. However, considering several newer studies, combined with a more rigorous systematic review methodology, our evaluation differed from these, indicating suggestive evidence of no association.

Some in vivo and in vitro studies carried out with talc samples.

Historical occupational talc exposure most often was estimated using duration of employment as a surrogate. The nomenclature of these classifications is simplified but follows the rationale of the corresponding U.S. IOM classifications for causation (8) (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. 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. Of three experimental animal studies of inhaled talc, only one mesothelioma was reported in a strain of rats prone to spontaneous mesothelioma.

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

Nineteen epidemiological studies (17 cohort study publications and two nested case-control studies) satisfied inclusion and exclusion criteria and were selected for full review to assess the possible relationship between occupational talc exposure and pulmonary cancers (specifically lung cancer and mesothelioma). Mortality in the cohort of talc miners and millers from Val Chisone, Northern Italy: 74 years of follow-up.

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.
