August 8th, 2008. A Meta-Analysis of Asbestos-Related Cancer Risk That Addresses Fiber Size and Mineral Type
(2007) recently analyzed by TEM archived air samples from the South Carolina plant to determine a detailed distribution of fiber lengths up to lengths of 40 μ m and greater. If similar data become available for Quebec, perhaps these two size distributions can be used to eliminate the discrepancy between these two studies.
August 8th, 2008. Sensitivity analysis of the relationship between disease occurrence and distance from a putative source of pollution
However, as the models appeared to be sensitive to modeling choices, we suggest that any analysis of disease risk around a putative source should be integrated with a careful sensitivity analysis and possibly with prior knowledge. The choice of prior distribution is extremely important and should be based on epidemiological considerations.

August 1st, 2008. Update of Potency Factors for Asbestos-Related Lung Cancer and Mesothelioma
, chrysotile or crocidolite) of an asbestos structure. An analysis is conducted to determine how well different KL and KM definitions are able to reconcile the discrepancies observed herein among values obtained from different environments.
July 25th, 2008. Environmental exposure to Libby asbestos and mesotheliomas
Results: These exposures are considered to be of a low degree of magnitude, but are similar to those in Western Australia's crocidolite mine at Wittenoom Gorge. An epidemic of mesothelioma can likely be expected from this type of asbestos contamination over the next 20 plus years.
June 24th, 2008. Separation and Characterization of Respirable Amphibole Fibers from Libby, Montana
Such harvesting of respirable fractions will allow toxicological studies to be conducted within a controlled laboratory setting, utilizing fiber sizes that may more accurately simulate historical exposure of Libby residents' lungs. Importantly, this work describes a method that allows the use of material enriched in more uniform respirable material than raw Libby 6-mix, making comparisons with other known fiber preparations more valid on a mass basis.
June 24th, 2008. Select mortality and cancer incidence among residents in various U.S. communities that received asbestos-contaminated vermiculite ore from Libby, Montana
No statistically significant excesses of asbestosis mortality similar to those in Libby were noted; however, 11 sites (plus a state with 6 pooled sites that were counted as 1 site) had excess rates of mesothelioma and cancer of the peritoneum, retroperitoneum, and pleura. Further investigation should be conducted at these sites with excess rates of mesothelioma and cancer of the peritoneum, retroperitoneum, and pleura by participating state health departments to determine whether exposure to Libby vermiculite might have been a contributing factor.
June 17th, 2008. Mapping the Risk of Mesothelioma due to Neighborhood Asbestos Exposure
Conclusions: Neighborhood exposure to asbestos can pose a serious risk to residents across a wide area.
June 6th, 2008. Excess of Mesotheliomas after Exposure to Chrysotile in Balangero, Italy
Conclusions: The cluster of 14 mesothelioma cases among workers who were active in the mine and 13 among other people exposed to Balangero chrysotile adds further evidence to the carcinogenicity of tremolite-free chrysotile.
June 4th, 2008. Mesothelioma due to environmental exposure to erionite in Turkey
It has also been confirmed that a genetic predisposition to erionite carcinogenesis is the cause of the mesothelioma epidemic in Cappadocia. Summary: The data obtained recently on the epidemiology, etiology, and pathogenesis of the mesothelioma due to erionite exposure in Turkey are described.
May 30th, 2008. Two cases of asbestosis and one case of rounded atelectasis due to non-occupational asbestos exposure
The three cases indicate that non-neoplastic, long-latency asbestos-related diseases which are usually observed as a consequence of occupational exposures, may rarely develop in subjects living in contaminated geographical sites and buildings. These unusual environmental diseases raise the diagnostic problem of differentiating them from other, more common respiratory illnesses, and impose the duties of patient notification, assessment and follow-up, to assess the possibility of progression of disease and increased neoplastic risk.
May 29th, 2008. Erionite-induced pleural plaques : Exposition to urban pollution in a female Turkish migrant in Germany
Short-term clinical and radiologic control of the patient will be necessary because of the risk of MPM. For epidemiologic considerations discussed referring to current literature, a growing incidence of this type of disease in migrants from high-risk areas must be reckoned with in Germany, even without exposition to asbestos.
April 16th, 2008. Exposition to asbestos dust in agricultural environment. Some significant exposure forms documented by the Hospital Unit of Occupational Medicine of Hospital Institute of Cremona
At the moment there aren't full-blown asbestos-linked pathology but these workers are potentially at risk of getting them. So it has an importance both on individual and global level for the rural area near Cremona.
April 16th, 2008. Case studies on the malignant mesothelioma in Pellezzano (SA
All five patients answered the questionnaire and a team of doctors performed an on-the-spot investigation. The studies verified the existence of two kind of asbestos exposure, professional (Cotton Manufacture, Construction, Foundry) and environmental (cement-asbestos pre-fabricated since 1980 earthquake), that have to be analyzed further.
April 9th, 2008. An evaluation of the risks of lung cancer and mesothelioma from exposure to amphibole cleavage fragments
Lawrence, NY talc does not produce mesotheliomas in animals while amphibole asbestos does. In sum, the weight of evidence fully supports a conclusion that non-asbestiform amphiboles do not increase the risk of lung cancer or mesothelioma.
March 19th, 2008. Erionite series minerals: mineralogical and carcinogenic properties
The larger surface area creates a wider platform for mineral-cell interaction and thus more possibilities of proliferative transformation of mesothelial cells. Consequently, understanding the exact mineralogical properties will help determination of the true carcinogenic mechanism(s) of the mineral for prevention and possibly treatment of malignant mesothelioma.
January 26th, 2008. Translocation pathways for inhaled asbestos fibers
25 microns) can travel larger distances due to low steric hindrance (in mesothelioma about 90% of fibers are ultrafine). Fibers translocation is a slow process developing over decades of life: it is aided by high biopersistence, by inflammation-induced increase in permeability, by low steric hindrance and by fibers motion pattern at low Reynolds numbers; it is hindered by fibrosis that increases interstitial flow resistances.
January 22nd, 2008. Risk assessment due to environmental exposures to fibrous particulates associated with taconite ore
77 excess cancer case in 1,000,000 lifetimes. Finally, we briefly review the epidemiology studies of grunerite asbestos (amosite) focusing on the exposure conditions associated with increased risk of human mesothelioma.
January 17th, 2008. Epidemiology of pleural mesothelioma in a population with non-occupational asbestos exposure
Conclusions: Environmental exposure to asbestos begins at birth and this may be important in the age of disease onset, if a threshold model for cancer initiation is operative. Both men and women had an excess risk of mesothelioma. Given that a family history of MPM was not common in this relatively homogenous patient group, a genetic predisposition to mesothelioma appears unlikely.
January 4th, 2008. Environmental mesothelioma associated with tremolite asbestos: Lessons from the experiences of Turkey, Greece, Corsica, New Caledonia and Cyprus
It can also elucidate the effects of fibers that behave like amphibole asbestos. However, this type of exposure is not useful for studying the potential effects of small amounts of asbestos in the ambient air of big cities due to the differing nature of the fiber types and modes of exposure between the regions.
