Heavy industrial exposure to asbestos causes lung cancer and mesothelioma, but it remains unknown whether much lower environmental exposure to asbestos also causes these cancers.

This study aimed to quantify the potential intradomiciliary exposure to asbestos in five Brazilian capital cities and possible effects on the respiratory system.
WHO Workshop on Mechanisms of Fibre Carcinogenesis and Assessment of Chrysotile Asbestos Substitutes
The WHO Workshop on Mechanisms of Fibre Carcinogenesis and Assessment of Chrysotile Asbestos Substitutes was convened at IARC in Lyon, in response to a request from the Intergovernmental Negotiating Committee (INC) for the Rotterdam Convention on the Prior Informed Consent Procedure for Certain Hazardous Chemicals and Pesticides in International Trade.
The toxicological response of Brazilian chrysotile asbestos: A multi-dose sub-chronic 90-day inhalation toxicology study with 92 day recovery to assess...
This study is the first to assess the cellular and pathological response in the rat lung to a well characterised aerosol of chrysotile asbestos in a 90 day sub-chronic inhalation toxicology study.
Reduction of the biological potential of chrysotile asbestos arising from conditions of service on brake pads
Data exist that show that chrysotile asbestos does not retain its mineral properties, or biological activity, at temperature far below the olivine transformation point. Temperatures hundreds of degrees below this point cause the mineral to lose structural water with accompanying crystal structure degradation.
This report presents the results of the study on the condition of the problem of the scattering of Airborne Fiber (Chrysotile fiber) in the buildings in which the fiber containing material (ACM) is used generally , in particular, at monastery, school, residential building in Bangkok Metropolis and in the peripheral provinces. This was organized to...
Comparison of calidria chrysotile asbestos to pure tremolite: inhalation bioperistence and histophathology following short-term exposure
The differences between chrysotile asbestos, a serpentine mineral, and amphibole asbestos have been debated extensively. Many studies have shown that chrysotile is cleared from the lung more rapidly than amphibole.
In December 1997 the European Commission (EC) adopted Directive 97/69/EC (O.J. L 343/19 of 13 December 1997; European Commission, 1997) in which criteria were established for the classification and labeling of synthetic mineral fibers.
One of the primary goals of WHO and its member states is that “all people, whatever their stage of development and their social and economic conditions, have the right to have access to an adequate supply of safe drinking water.” A major WHO function to achieve such goals is the responsibility “to propose regulations, and...
In the aftermath of the September 11th atrocity, which destroyed New York City's World Trade Center (WTC), questions have been raised conceming the risk of asbestos-related cancer from inhaling the dust.
To investigate whether claims of a physical and chemical change to chrysotile fibres in a cement matrix (A/C), are valid and merit further investigation.
A group of researchers conducted a case-control, interview-based study of the risk of developing cancer from asbestos in drinking water. An area that included Everett, Washington, was selected for the study because of the unusual high concentration of chrysotile asbestos in drinking water from the Sultan River.
A survey of the health problems associated with the production and use of high density chrysotile products
The last 20 years or so have seen enormous advances in our knowledge and understanding of asbestos-related disease. Unfortunately, governments and regulatory agencies have largely ignored the findings. Lawyers and pressure groups vigorously resist them.
This review provides a basis for substantiating both kinetically and pathologically the differences between chrysotile and amphibole asbestos.
Of the major asbestos related diseases, mesothelioma is the most sensitive and specific indicator of the adverse health effects that have resulted from airborne exposures to asbestos fibres.
