asbestos exposure characterize

Pleural plaques are the most common manifestations of asbestos exposure; by occupation, the highest rate (58%) has been reported in insulation workers [American Thoracic Society 2004; Peacock et al. 2000]. The presence of pleural plaques in the general environmentally exposed population in developed societies is in the range of 0.5%-8% …

Data from a population-based case-control study were used to characterize associations between workplace exposure to silica and asbestos and bladder cancer among men. Bladder cancer ... Exposure to the lowest tertile of asbestos exposure relative to the unexposed was associated with an increase in odds of bladder cancer …

TEM–EDS–SAED analysis is generally used to characterize the fine fraction of particles (less than 5 μm) and those particles that require crystallographic identification such as asbestos.

The potential for para-occupational (or "take-home") exposure to a number of chemicals has been recognized for over 60 years. We conducted a literature review in order to characterize reported cases of asbestos-related disease among contacts of workers occupationally exposed to asbestos. Over 200 published articles were evaluated.

Exposure to asbestos can be grouped into occupational and non-occupational exposure. Occupational exposure includes asbestos miners, millers, and workers involved in the manufacturing of asbestos products. ... Mesothelioma subtypes have different characteristics, prognoses, and outcomes. Research to further …

Asbestos is the name given to a group of naturally occurring minerals that are resistant to heat and corrosion. Asbestos has been used in products, such as insulation for pipes (steam lines for example), floor tiles, building materials, and in vehicle brakes and clutches. Asbestos includes the mineral fibers chrysotile, amosite, crocidolite ...

Asbestosis is a form of interstitial pulmonary fibrosis caused by asbestos exposure. Asbestosis can cause progressive dyspnea on exertion, nonproductive cough, and fatigue. ... (International Classification of Radiographs of Pneumoconioses) is used to characterize the presence and severity of pneumoconioses based on size, shape, location, and ...

Further, talc-based cosmetics may be an overlooked and difficult to characterize source of exposure to asbestos, a known carcinogen. Keywords: Asbestos, talc, personal care products, cancer risk. Talc is a mineral ingredient that has been used in personal care products for decades. The mineral can be used to improve the texture and …

The relationship between asbestos exposure and disease has been well documented, although questions persist as to variation in risk by the type and length of fiber. For a series of jobs with potential asbestos exposure, the primary fiber type (e.g., amosite, anthophylite, chrysotile, crocidolite, or tremolite) and fiber length were identified ...

Methods for the measurement and analysis of asbestos and other fibers in air, water, dust, and bulk materials vary by type of scenario and according to applicable laws and rules. Two surveys and a focus group were used to identify the most important information gaps in asbestos exposure assessments.

Also, although asbestos ore is no longer mined in the United States (4), some U.S. mine workers might remain at risk for exposure to asbestos contained in other ores. To characterize trends …

Furthermore, not even surveys have been conducted in Italy to characterize the correlation between asbestos exposures and the possible occurring of asbestos-related disease. Our objectives are the following: i) to assess and quantify the asbestos exposure cases, ii) to describe the nature and the frequency of asbestos-related diseases among ...

Asbestos containing materials are a component of many vehicle brake systems, including those found in some light aircraft. To characterize the asbestos exposure that results from the installation and maintenance of these components, an aircraft fitted with asbestos containing brake pads had brake changes performed while both area and personal air …

Asbestos Exposure. Table Of Contents [ show ] Exposure to asbestos can pose significant health risks if fibers become airborne. Asbestos exposure can lead to mesothelioma, lung cancer and …

The risk of asbestos exposure on the job was highest before the 1970s, though asbestos exposure can still occur today. Because it takes a long time to develop symptoms, providers are still diagnosing many new cases of asbestosis. Regulation of on-the-job exposure to asbestos has reduced the risk of asbestosis, but even with these …

To better characterize the take-home asbestos exposure pathway, a study was performed to measure the relationship between airborne chrysotile concentrations in the workplace, the contamination of work clothing, and take-home exposures and risks. The study included air sampling during two activities: (1) contamination of work clothing by ...

The understanding by industrial hygienists of the hazards of asbestos and appropriate ways to characterize and control exposure has evolved over the years. ... These early developments set the stage for decades of additional study on asbestos exposure potential and risk of disease. This was followed by the application of …

The potential for para‐occupational (or take‐home) exposures from contaminated clothing has been recognized for the past 60 years. To better characterize the take‐home asbestos exposure pathway, a study was performed to measure the relationship between airborne chrysotile concentrations in the workplace, the contamination of work clothing, and …

Introduction. Briefly this section reviews the uses of asbestos, how people may be exposed to it, the magnitude of exposure, and how it is measured.

This could release asbestos fibers into the air. Applies a wetting agent to the asbestos material with a hand sprayer that creates a fine mist before removal. Wet fibers do not float in the air as easily as dry fibers and will be easier to clean up. Ensures the work site is clearly marked as a hazard area.

Of interest, these exposure excursions were observed despite the fact that the bulk ZAI material often contains less the 0.1% asbestos, well below the 1% trigger level used by U.S. regulatory agencies to characterize building materials as …

An increased risk for Systemic Autoimmune Diseases (SAID) has been reported in Libby, Montana, where extensive exposures to fibrous amphiboles occurred due to mining and use of asbestos-laden vermiculite. In addition, positive antinuclear autoantibody tests are associated with exposure to Libby Asbestiform Amphiboles (LAA) in both humans and …

ASBX unlocks the crucial information you need if you or a loved one has been diagnosed with mesothelioma or lung cancer due to asbestos exposure. Search from 67,722 Unique Asbestos Exposure Sites. Find 477 Military Installation with Documented Exposure. Explore 249 Navy Ships with …

Diseases from asbestos exposure are generally thought to occur after exposures lasting a year or longer.12 ... In an air monitoring study done to characterize exposures during the overhaul phase, area sampling for asbestos showed an average sample concentration of 0.073 fibers/cc across 46

The study of occupational exposure to asbestos has been an ongoing activity for at least 75 years, dating back to the papers of Merewether and Price (1930). Since that time, literally tens of thousands of air samples have been collected in an attempt to characterize the concentration of asbestos associated with various activities.

Short-Term Asbestos Exposure. Short-term asbestos exposure involves incidents that last less than a few days. Certain extreme events, such as the toxic exposure caused by the 9/11 attacks, can lead to a high risk of illness later in life. But in general, the health risk from short-term asbestos exposure is low.

Objective Previous studies considered the role of occupational causes in kidney cancer but were limited by small sample sizes and imprecise exposure assessment. This study examined the relationship between occupational exposure to asbestos and the risk of kidney cancer across a range of jobs in a large, population-based case-control …

Unlike malignant mesothelioma, the link between asbestos exposure and cystic mesothelioma is unclear. Some studies suggest cystic mesothelioma develops in response to foreign fibers and dust. …
