Vermiculite ore is a naturally occurring fibrous mineral widely used in various consumer products, such as attic insulation, lawn and garden products, and fireproofing material. While most vermiculite ore and products do not pose a health hazard, the vermiculite mined from Libby, MT was contaminated with naturally occurring asbestos. The federal Agency for Toxic Substances and Disease Registry (ATSDR) has documented a significant number of asbestos-related deaths among Libby residents… 

Select Mortality and Cancer Incidence Among Residents in Various U.S. Communities that Received Asbestos-Contaminated Vermiculite Ore from Libby, Montana

In response to the significantly elevated asbestosis mortality rates found in Libby, Montana, in 2000, this analysis evaluated whether other communities throughout the United States that received

Mortality from asbestos-associated disease in Libby, Montana 1979–2011

The results suggest that the general population may be experiencing asbestos-related effects, not just former vermiculite workers, and additional research is needed to determine whether SMRs remain elevated after controlling for secondary exposure, such as living with vermicULite workers.

Radiographic Evidence of Nonoccupational Asbestos Exposure from Processing Libby Vermiculite in Minneapolis, Minnesota

The hypothesis that community exposure to asbestos-contaminated vermiculite originating from Libby, Montana, is associated with measurable effects based on radiographic evidence is supported.

Rural public health policy models to address an evolving environmental asbestos disaster.

The history and outcomes of asbestos exposure in a rural community are described and 3 models that provide public health policy insights related to rural health and health care for a community affected by both a sentinel and ongoing environmental event are discussed.

Comparative Long-Term Toxicity of Libby Amphibole and Amosite Asbestos in Rats After Single or Multiple Intratracheal Exposures

There is a possibility of greater long-term pathological changes with repeated lower LA dose exposures, which more accurately simulates chronic environmental exposures.

A clinical assessment and lung tissue burden from an individual who worked as a Libby vermiculite miner

The present case involves the clinical assessments of an individual who worked at the vermiculite mine from 1969 to 1990 and developed a clinical picture that included “asbestos-like” pathological features and eventually an adenocarcinoma.

Modern Environmental Health Hazards: A Public Health Issue of Increasing Significance in Africa

Recent evidence of human exposure to and health effects from MEHHs, and their occurrence in environmental media and consumer products are reviewed to highlight the growing significance of these hazards as African countries experience urbanization, industrial growth, and development.

In vitro determinants of asbestos fiber toxicity: effect on the relative toxicity of Libby amphibole in primary human airway epithelial cells

The results of this study show that the particle length and particle surface area are highly correlated metrics that contribute significantly to the toxicological potential of these amphibole samples with respect to the inflammogenic response induced in airway epithelial cells.

Use of Direct Versus Indirect Preparation Data for Assessing Risk Associated with Airborne Exposures at Asbestos-contaminated Sites

This study finds that the choice of preparation technique used in estimating airborne amphibole asbestos exposures for risk assessment is generally not a significant source of uncertainty and uncertainties associated with the use of airborne Libby-type amphibole exposure measurements derived from indirect preparation analysis are low.

Childhood exposure to Libby amphibole asbestos and respiratory health in young adults



Radiographic abnormalities and exposure to asbestos-contaminated vermiculite in the community of Libby, Montana, USA.

The purpose of this analysis was to identify and quantify asbestos-related radiographic abnormalities among persons exposed to vermiculite in Libby and to examine associations between these outcomes and participants' self-reported exposures.

Screening for asbestos-induced diseases in Finland.

The screening acted as a preliminary survey to prompt further national follow-up of asbestos-induced diseases among the workers who have been exposed to asbestos.

Pulmonary changes after exposure to vermiculite contaminated with fibrous tremolite.

The lack of significant parenchymal radiographic, spirometric, and DLCOsb changes most likely reflects the low cumulative fiber exposure.

The Composition and Morphology of Amphiboles from the Rainy Creek Complex, Near Libby, Montana

Abstract Thirty samples of amphibole-rich rock from the largest mined vermiculite deposit in the world in the Rainy Creek alkaline-ultramafic complex near Libby, Montana, were collected and analyzed.

Radiographic abnormalities among Finnish construction, shipyard and asbestos industry workers.

Exposure to asbestos dust has been common in ordinary construction work, and, consequently, radiographic abnormalities (mostly pleural) occur frequently among active and retired construction workers.

[Asbestos-related lesions detected by high-resolution CT scanning in asymptomatic workers. Specificity, relation to the duration of exposure and cigarette smoking].

It is suggested that pulmonary or pleural involvement can be shown by HRCT before the onset of any clinical symptomatology with high sensitivity and specificity, and the severity of lung involvement among asbestos-exposed workers are related to the duration of exposure.

Asbestos disease in family contacts of shipyard workers.

It is probable that asbestos exposure in the household places these family members at risk for mesothelioma and lung cancer.

With advances in chest radiology, including high-resolution CT, radiologists play a key role in the clinical evaluation of occupational lung diseases and should continue their involvement in the diagnosis and treatment of these diseases.

High-resolution computed tomography in the early detection of asbestosis

The study strongly suggests that for asbestos exposed workers with an ILO classification of < 1/0 and functional impairment, an HRCT examination should always be considered.
