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. Webbreathing in loose talc powder may cause lung effects, such as coughing, trouble breathing, decreased lung function and fibrosis; and. WebThe final assessment for talc found two possible health concerns. Hazard conclusions were determined using the U.S. Institute of Medicine (IOM) framework (8).

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. The results indicate that the talc industry exerted considerable influence over three key areas: regulatory proceedings at the FDA; testing methods and the manipulation of test results (including undisclosed results); and press coverage and the medical literature. 3.2. *Correspondence: Heather N.

This review is now 12 years old, and several studies and reviews on talc exposure and pulmonary cancer risk have been published since the 2010 IARC Monograph (1, 5, 6). Try a new one!

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). The TROG-2 is a fully revised and nationally re-standardised version of the widely used TROG. 0000012875 00000 n Regulatory toxicology and pharmacology : RTP, Abstract This study characterizes airborne asbestos exposures resulting from the adult application of cosmetic talc body powders spiked with known concentrations of tremolite. When stratified by duration of exposure, no exposure-response pattern was found (1, 48, 51). %%EOF (2009) 48:646790. 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).

Inhalation of talc baby powder by hamsters. Mesothelioma associated with the use of cosmetic talc. Why is a Test of Abstract Language Comprehension needed? EPA Doc. Across all cohort studies, observed numbers of deaths for site-specific cancers among talc miners and millers (either combined or separately) were compared with expected numbers based on national and/or regional reference rates. how do you think he feels? Talc is a hydrous magnesium sheet silicate (Mg3Si4O10(OH)2) with particles that are plate-like in structure. Specifically, this framework involves reviewing and evaluating studies according to specific quality domains (e.g., outcome assessment and exposure characterization), each of which includes two to seven individual metrics assessing specific study features. doi: 10.1097/JOM.0000000000001700, 57. NTP Technical Report on the Toxicology and Carcinogenesis Studies of Talc (CAS No. 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.

Other studies have reported increases in macrophages and other inflammatory markers after whole-body exposures, but again only with high talc concentrations. 0000004445 00000 n Mortality experiences among talc workers: a follow-up study.

As a result, the validity and relevance of these findings remains unclear; however, the epidemiological studies reflect potential risks associated with exposures to talcs including whatever accessory minerals and contaminants that might be present. Bronchioalveolar lavage (BAL) fluid was collected and assessed at 1 day post exposure (all doses) or 1, 4, 7, and 14 days after talc administration (3.75 mg/100 g). It has been concluded that there was an inadequate evidence of carcinogenicity in experimental animals and the degree of evidence in short-term tests for genetic activity has been found to be inadequate. J Occup Med. This petition was denied.15 In 2000, talc was nominated for review in the NTP 10th Report on Carcinogens because the NTP bioassay Webassessment of talc. Eur Resp J.

The increased risk among those hired before 1955 was strongest among miners (SMR = 3.94; 95% CI: 2.336.22, based on 18 cases) and not elevated among millers (SMR = 1.28; 95% CI: 0.512.63, based on 7 cases). 0000018699 00000 n 7.2.1 Environmental media, food and drinking A brief overview of the quality evaluation results is presented below, followed by a summary of study findings.

Five additional mortality studies evaluated specific causes of death among New York talc miners and millers (4143, 46, 47). We performed literature searches using PubMed and Web of Science and used existing agency reviews as a basis for cross-referencing critical studies. The Italian, Norwegian, French, and Austrian talc mines all produced talcs described as non-asbestiform with various accessory minerals including small amounts of chlorite and quartz (30, 50, 52). Cincinnati, OH: U.S. Dept. 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. (2007) 29:75760. (2002) 46:57585. The higher quality studies generally did not demonstrate an association, or attributed observed increased risks to potential confounding by cigarette smoking, as risks did not correlate with indicators of talc exposure. 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).
