Asbestos-contaminated vermiculite attic insulation (VAI) produced from a mine near Libby, Montana, may be present in millions of homes along with other commercial asbestos-containing materials (ACM). The primary goal of the research described here was to develop and test procedures that would allow for the safe and effective weatherization of low-income homes with asbestos. The presence of asbe...

OBJECTIVES The aim of the study was to analyze the correlation between pulmonary concentrations of asbestos bodies and asbestos fibers and to characterize asbestos body counts from lung tissue of Finnish patients occupationally exposed and unexposed to asbestos. METHODS Ninety-nine surgically treated lung cancer patients were investigated. The number of asbestos bodies in iron-stained 5-micro...

Asbestos is still used in Mongolia in the energy and construction sectors, among others. However, limited data is available on asbestos consumption and asbestos-related disease in Mongolia. The purpose of this paper is to present the available information on the importation of asbestos into Mongolia. We used data on annual asbestos imports between 1996 and 2014 from Mongolian Customs Statistics...

Asbestos is a carcinogen that causes diseases such as mesothelioma and lung cancer in humans. There was a sharp increase in the use of asbestos in Korea in the 1970s as Korea's economy developed rapidly, and asbestos was only recently banned from use. Despite the ban of its use, previously applied asbestos still causes many problems. A series of asbestos-related events that recently occurred in...

The alarming hazardous nature of asbestos makes it the foremost among toxic fugitive dusts. The biochemical mechanisms responsible for the diverse biological effects of asbestos, such as fibrosis, asbestos bodies, pleural plaques, respiratory difficulty, cancer, and cytotoxicity, are being studied in this laboratory. As asbestosis progresses in guinea pigs, along with reticulum formation, lysos...

environmental pollutions are in considerable attention in steel industries in iran, where mostly are located around isfahan. therefore, an investigation was done mainly on the industrial pollution and waste related to the isfahan steel complex. a plant was installed to collect the uncontrolled fumes, gases and particulates from blast furnace number ii during tapping. this plant collects about 2...

BACKGROUND The association between pleural plaques and pleural mesothelioma remains controversial. The present study was designed to examine the association between pleural plaques on computed tomography (CT) scan and the risk of pleural mesothelioma in a follow-up study of asbestos-exposed workers. METHODS Retired or unemployed workers previously occupationally exposed to asbestos were invit...

Environmental and occupational exposure to asbestos is among the established risk factors for lung cancer, the leading cause of cancer-related deaths in the United States. This link between exposure to asbestos and the excessive death rate from lung cancer was evident in a study of former workers of an asbestos pipe insulation manufacturing plant in Tyler, TX. We performed comparative proteomic...

To establish reference values for pulmonary asbestos and non-asbestos fiber concentrations in rural Korean residents, and their comparison with those of urban Korean residents and the Japanese, autopsied lung samples from 22 subjects (20 males and 2 females), in Pohang, without known occupational asbestos exposure histories, were analyzed for asbestos and non-asbestos fibers, using transmission...

Wollastonite fibers were tested in vitro for their ability to produce reactive oxygen species (ROS) with two different systems: a cell-free reactive mixture containing deoxyribose and a polymorphonuclear leukocyte suspension. After adding the fibers, we measured the thiobarbituric acid-reactive substances produced by deoxyribose degradation and luminol-enhanced chemiluminescence, respectively. ...
