The increased risk appeared to be limited to workers hired before 1955 (SMR pre-1955: 2.86; 95% CI: 1.904.14), as the SMR for workers hired after 1955 was 0.83 (95% CI: 0.172.42).

An additional 10 epidemiological studies were identified through supplemental searches using narrower terms (e.g., lung cancer, mesothelioma, millers, miners) and considering the tertiary literature (reviews, gray literature). Washington, D.C.: Office of Chemical Safety and Pollution Prevention-U.S. Environmental Protection Agency (EPA) (2018). The safety of talc has been the subject of much debate through the years, partly because the relationship between talc and asbestos is commonly misunderstood. Wagner JC., Berry G, Hill RJ, Skidmore JW, Pooley FD. Phone: +44(0)203 564 6419 Wild et al. Pauluhn J. Derivation of occupational exposure levels (OELs) of low-toxicity isometric biopersistent particles: how can the kinetic lung overload paradigm be used for improved inhalation toxicity study design and OEL-derivation? 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. Requires the child use their own knowledge to: Involves the child to have the ability to think about the future and their past to be able to: Children who have concrete thinking often struggle with concepts and words that arent physically present, or have one specific meaning or explanation, or can change. 1322 50 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. 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). Standard scores, percentile ranks, and age equivalents are provided for each domain, and for overall general development if all five domains are tested. 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. 56. Our conclusions regarding hazard for each cancer type, based on the IOM classification system (8), are described below and in the protocol, and visualized in Table 2. 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. Overall, the animal studies all employed designs that properly incorporated a control group for comparison, including randomly allocating test animals into experimental groups to reduce potential bias. 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. Rubino et al. Figure 2. 0000013012 00000 n Application of Systematic Review in TSCA Risk Evaluations. (1974) 16:3459. The literature search and selection process identified 23 primary studies that assessed exposure to talc and pulmonary cancer risks in humans (n = 19) and animals (n = 3). In mice, intra-alveolar macrophages were focally aggregated. Talc was negative in a reverse mutation assay Salmonella typhimurium strains TA1530 and G46. (17, 20) exposed Westar rats to Italian 00000 grade talc, superfine chrysotile asbestos, or laboratory air (controls), via whole-body inhalation.

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. These workers were clearly and highly exposed to the talcs: all except the Norwegian cohort reported statistically significant excess mortality due to pneumonoconiosis, a group of non-malignant respiratory diseases caused by heavy exposure to dusts. Fiume MM, Boyer I, Bergfeld WF, Belsito DV, Hill RA, Klaassen CD, et al. doi: 10.1097/JOM.0000000000000992, 52. Given the huge number of consumer products, it is not possible to calculate the, International journal of cosmetic science. 0000004318 00000 n Epidemiological studies were selected to include groups exposed to talc, including talc miners and millers (the groups historically most highly exposed) as well as groups potentially exposed to cosmetic talcum powders and other products containing talc. (43) was the only study to report a statistically significant excess risk of lung cancer (SMR = 2.32; 95% CI: 1.573.29). Am J Epidemiol.

After excluding studies based on exposure route, non-pulmonary outcome, and administration of talc as part of a mixture, three studies remained for study quality evaluation (1719). Roggli VL, Carney JM, Sporn TA, Pavlisko EN. 0000018699 00000 n None of the 17 cohort studies identified an increased risk of malignant pleural or peritoneal mesothelioma among talc miners and millers. 0000011243 00000 n Two nested case-control studies were conducted in tandem with occupational mortality analyses (30, 31). The SMRs for the eligible cohorts ranged from 0.92 in a Norwegian cohort [] to 4.50 in a Chinese The Cosmetic Ingredient Review Expert Panel (Panel) assessed the safety of talc for use in cosmetics. Moline J, Bevilacqua K, Alexandri M, Gordon RE. We employed qualitative and hierarchical or tiered approaches to arrive at the overall study quality score, tailored to each study type and outcome. DAYC-2 was normed on a national sample of 1,832 children. We performed literature searches using PubMed and Web of Science and used existing agency reviews as a basis for cross-referencing critical studies. Overall ratings of medium quality for 14 cohort studies primarily were driven by potential confounding/variable control (especially for lung cancer and cigarette smoking) and exposure assessment, including characterization of talc exposure (e.g., by job, exposure concentration level and duration). 0000014600 00000 n Exposure to compounds in consumer products can be assessed using the computer program ConsExpo (Consumer Exposure). (15, 18) exposed groups of 100 Syrian golden hamsters to whole-body inhalation of Johnson's Baby Powder at 8 mg/m3 for 3, 30, or 150 min/day, for 5 days/week for 30 days, or for 30 or 150 min/day, 5 days/week, for up to 300 days.

Outcome assessment for these studies typically encompassed a full histological examination or autopsy; clinical and body weight monitoring was also conducted in two of the studies (15, 18, 19). A nested case control study of lung cancer among New York talc workers. exposure to the perineal area from the use of certain products containing talc is a possible cause of ovarian cancer. doi: 10.1002/ajim.4700170408, 53. EPA Doc. No epidemiological studies were identified that assessed consumer use of talc and talcum powder products. Our systematic review of talc and pulmonary cancers generated suggestive evidence of no association for exposure to talc and lung cancer and pleural mesothelioma. EPA. Talc: may be harmful to your lungs (difficulty breathing, scarring of the lungs) if you breathe in loose powder 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. In the time-course evaluation, most findings returned to control levels within 14 days.

In summary, no excess of malignant mesothelioma has been reported in any of the available epidemiological studies of talc miners and millers heavily exposed to talc. (2017) 60:82130. The normalized lung talc burdens for both mice and rats were lower at the lowest exposure level than at the two higher exposure levels; however, the difference was statistically significant only for the rats. 0000012150 00000 n J Env Pathol Tox.

Questions relate to the immediate environment and require the child to think concretely e.g. In its most recent review of talc, the International Agency for Research on Cancer (IARC) concluded [t]here is inadequate evidence in humans for the carcinogenicity of inhaled talc (4). Talc and mesothelioma: mineral fiber analysis of 65 cases with clinicopathological correlation. 19. 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.
