Tissue burden of asbestos in nonoccupationally exposed individuals from east Texas
The potential for asbestos exposure among members of the general population is appreciable, considering its widespread use in many products. This study examined tissue burden of asbestos in such a population. A group of 33 individuals…

A comparison of asbestos burden in lung parenchyma, lymph nodes, and plaques
…plaques and pleura are not useful for mineral analysis, and they designed the study to test it. Tissue was collected at autopsy at the General Hospital of Monfalcone, Italy, from eight former shipyard workers (seven men…

Asbestos content of omentum and mesentery in nonoccupationally exposed individuals
…electron microscopy for defining the asbestos burden in digested lung, omentum, and mesentery tissues from individuals considered as representing the general population in East Texas. The findings, when compared with previous data from occupationally exposed individuals…

Asbestos content of lung tissue, lymph nodes, and pleural plaques from former shipyard workers
…in tissue taken at autopsy from eight former shipyard workers, aged 58 to 82, at the General Hospital of Monfalcone, a shipyard town in northeastern Italy. Seven had work histories of 6 to 46 years in…

Tissue burden evaluation of elongated mineral particles in two individuals with mesothelioma and whose work history included manufacturing tile
…1, and 1944 and 42 in two Case 2 samples. The laboratory's general-population upper limit for lung tissue was 20 or fewer ferruginous bodies per gram of wet tissue. Lung asbestos fiber counts, per…

Relationships between ferruginous bodies and uncoated asbestos fibers in lung tissue
…Americans to amosite. The levels of ferruginous bodies in both groups suggest exposures above those expected in the general population. Uncoated chrysotile levels were below the ranges reported previously for some general populations. The data suggest…

Malignant mesothelioma from neighborhood exposure to anthophyllite asbestos
…leu M1 antigen. Anthophyllite fibers were > 5 microm in length in lung tissue compared to 3 microm from a general population study. Anthophyllite asbestos has been associated with neighborhood environmental exposure and pleural plaques; we…

Analysis of asbestos concentration in 20 cases of pseudomesotheliomatous lung cancer
…at least one sample above 20 per gram of wet tissue, while six were within the 0 to 20 per gram the authors expected in the general population. Uncoated asbestos was found in all 20 cases…

Mesothelioma in an individual following exposure to crocidolite-containing gaskets as a teenager
…per gram of deparaffinized (wax-removed) wet tissue. Two of the authors' laboratories use 20 or fewer per gram of wet tissue as the general-population level. Electron microscopy at 15,000 times magnification detected only…

Quantitative analysis of asbestos burden in a series of individuals with lung cancer and a history of exposure to asbestos
…Seventeen of the 20 cases were positive for ferruginous bodies (which were morphologically consistent with asbestos bodies). Five of these were found to have concentrations within the range used in our laboratory for the general population (

A technical comparison of evaluating asbestos concentration by phase-contrast microscopy (PCM), scanning electron microscopy (SEM), and analytical transmission electron microscopy (ATEM) as illustrated from data generated from a case report
…333 asbestos fibers per gram of deparaffinized wet tissue. Both laboratories found asbestos bodies above the level the authors cite as the upper limit expected in the general population. The authors calculated that 97% of the…

Familial mesothelioma: a report of two families
…asbestos bodies per gram of wet lung tissue. This was well within the lower limits seen in the general urban population with no occupational history of asbestos exposure. The authors concluded that genetic factors may be…

Analysis of asbestos fiber burden in lung tissue from mesothelioma patients
…those without, but the authors found the ranges too wide to predict asbestosis from fiber counts. The authors concluded that most patients had a confirmed asbestos burden above general population levels, often of mixed types. They…

Asbestos content in the lymph nodes of nonoccupationally exposed individuals
…However, no information exists as to asbestos content in lymph nodes from the general population. The study cohort consisted of 21 individuals previously defined as nonoccupationally exposed to asbestos. Tissue burden of asbestos obtained from lung…

Comparison of light and electron microscopy for defining occupational asbestos exposure in transbronchial lung biopsies
…past occupational exposure is examined. Simulated transbronchial biopsy samples and open lung biopsy samples were collected from autopsy material from 12 former amosite asbestos workers and ten persons from the general population. Tissue evaluation included (1…
