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). 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. 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. EPA. Reported functions of talc in cosmetics include abrasive, TALC is a set of learning modules covering all aspects of teaching and learning consultation skills. 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). The authors reported issues with the consistency of administration of talc aerosol over some weeks in the middle of the study, likely resulting in increased talc exposure. Proposed risk management objectives set quantitative or qualitative targets to be achieved by the implementation of risk management regulations, instrument(s) and/or tool(s) for a given substance or substances.

Mortality patterns among miners and millers on non-asbestiform talc: Preliminary report. 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 cancer and pleural mesothelioma, integrating epidemiology, toxicology, and studies informing potential underlying modes of action. Additionally, the NTP (19) study involved the use of micronized talc, which has a smaller aerodynamic diameter than mined and milled talcs and talc used in talcum powder products. 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).

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). Talc was administered to both species for 6 h per day, 5 days per week, for a total of 20 exposure days at talc concentrations of 0, 2, 6, or 18 mg/m3. For pulmonary cancers, it is therefore plausible that talc could cause irritation and a cascade of inflammatory mechanisms. Top mental health tools all in one place. 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).
