Public comments received on the draft screening assessment and risk management scope However, considering several newer studies, combined with a more rigorous systematic review methodology, our evaluation differed from these, indicating suggestive evidence of no association. Other studies have reported increases in macrophages and other inflammatory markers after whole-body exposures, but again only with high talc concentrations. Wergeland E, Andersen A, Baerheim A. Morbidity and mortality in talc-exposed workers. The authors evaluated, New solutions : a journal of environmental and occupational health policy : NS. In:Dusts and Disease, Lemen R., Dement J.M, , editors. 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. Because the case-control studies were nested within cohorts, we did not expect substantive differences in quality. Therefore, the large amount of available animal and clinical data the Panel relied on in assessing the safety of talc only. 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). 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).

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? We provide specialist speech and language therapy services for children with voice difficulties. While some cohort mortality studies reported an association between occupational talc exposure and lung cancer mortality, additional epidemiological investigations reported no such association or attributed observed increased risks to potential confounding by cigarette smoking, as risks did not correlate with indicators of talc exposure (4347). Two groups of 50 hamsters also were exposed to laboratory air as a control for 30 or 300 days. Examination of talcum products commonly available on retail shelves found fiber contents ranging from 8 to 30% by count, with an average of 19%, and the levels of cobalt, nickel, chromium and manganese were low. Considering the totality of the evidence, we conclude that there is suggestive evidence of no association between inhaled talc and lung cancer at human-relevant exposure levels. I have just had a review of his statement and they are concerned about his TALC 2 results he scored level 2 and they have said he should be at level 4, They said he has no imagination and is forgetful, he finds English confusing and he does not understand it but is good at spelling.
