Asbestos exposure is an impetus for disease development, its carcinogenicity for the mesothelium and lung tissue is well documented. One interesting study that examines this issue is called, Silica, asbestos, man-made mineral fibers, and cancer by Kyle Steenland and Leslie Stayner - Cancer Causes and Control - Volume 8, Number 3 / May, 1997. Here is an excerpt: Abstract - Approximately three million workers in the United States are estimated to...more
While studying the impact that asbestos dust has on workers, it is important to examine multiple factors such as data regarding smoking habits, age and other clinical and radiologic data. One interesting study is called, The role of catalytic iron in asbestos induced lipid peroxidation and DNA-strand breakage in C3H10T1/2 cells. By C. J. Turver and R. C. Brown - Br J Cancer. 1987 August; 56(2): 133136. Here is an excerpt: Abstract - The involvement of catalytic iron in the vitro activities of crocidolite asbestos has been investigated. Exposure of C3H10T1/2 cells to either the UICC crocidolite standard reference sample or a non fibrous (milled) derivative resulted in an increase of thiobarbituric acid reactive substances. This catalytic activity was inhibited by pretreatment with the iron chelator desferrioxamine. The effect of this activity on cellular DNA was measured in an assay based on the production of DNA-strand breaks. Increased levels of DNA-strand breaks were detected in cultures treated with both the milled and UICC crocidolite. Inclusion of desferrioxamine with the asbestos inhibited DNA-strand breakage. It is concluded the catalytic iron present on the dust is...more
Exposure to hazardous asbestos has been a problem for over a century. The common form of exposure typically came from the workplace. However, that has changed as asbestos has been found in the water supplies of various municipalities. One interesting study is called, Cancer mortality in relation to asbestos in municipal water supplies. By Wigle...more
One problem that has plagued spouses of the deceased workers that were exposed to asbestos is showing that mesothelioma was the cause of death. There is some evidence to suggest that the incidence of mesothelioma has been grossly underestimated. One interesting study is called, Validation of death certificates in asbestos workers by M. L....more
One question that has puzzled many researches is whether or not there is a definitive threshold regarding levels of asbestos exposure and disease development. One interesting study that explores this issue is called, Asbestos - the TLV approach - Ann N Y Acad Sci. 1976;271:152-69. by Nicholson WJ. Here is an excerpt: Abstract - A review of the control of carcinogenic exposures using the TLV approach presents a prospect of limited effectiveness. With asbestos, as with any carcinogen, no threshold is known below which no health effect may be manifest. At best, we have only limited dose-response information at levels much above those of practical concern. In the case of asbestos, current exposures can only be described crudely at any level of exposure, and health effects are only known for past high, but ill-defined, exposures. Limited information exists on the effects of synergistic interactions with other materials. The current U.S. TLV, based on data concerned with occurrence of asbestosis, has not been evaluated with regard to possible effectiveness in the prevention of asbestos cancer. Yet cancer is the heart of the asbestos-hazard problem. Finally, enforcement of the existing...more
Asbestos exposure has been known to cause cell transformation and chromosomal mutations. One group of workers that has been extensively studied is factory employees in London. One interesting study is called, Mortality from all cancers of asbestos...more
Asbestos workers that were smokers have an increased incidence of disease. Another interesting study on point is called, Cigarette smoke increases the penetration of asbestos fibers into airway walls. By D. McFadden, J. Wright, B. Wiggs, and A....more
