Asbestos problems in Montana and California

Our plain-English summary of Asbestos problems in Montana and California, by C. Maynard (Environmental Science & Technology, 2004).

In plain English

This item is a letter to the editor, not a research study. It presents no original research data, methods or measurements of its own. The author, a resident of Libby, Montana, was commenting on a news article titled "Asbestos investigation under way." The author wrote that the toxic exposure in Libby, which the author said was caused by industry, was not confined to miners and their family members but reached the entire population. The author cited U.S. Agency for Toxic Substance Disease Registry medical screening as showing this. The author stated that the planned cleanup would not be thorough. One reason given was that the EPA and other agencies were assessing tremolite risk in Libby using a single order of magnitude increase in toxicity over chrysotile. The author said this conflicted with the 2 orders of magnitude and above factor observed in tremolite exposure scenarios. The author also mentioned claims of a lack of money for cleanup. The author concluded that, until things changed, Libby residents would suffer excess mesothelioma and likely additional pleural scarring of the lungs.

What the study did and found

• Design: Letter to the editor commenting on a news article; no original research
• Who was studied: No study population. The writer is a resident of Libby, Montana, writing about the people of Libby.
• Exposure: Tremolite exposure in Libby, Montana, which the writer said was caused by industry, discussed in comparison with chrysotile
• Main results:
  • The writer stated, not as a finding of this letter, that exposure in Libby affected the entire population and not just miners and their families. The writer cited U.S. Agency for Toxic Substance Disease Registry medical screening as the source.
  • The writer stated that the planned cleanup in Libby would not be thorough.
  • The writer stated that the EPA and other agencies were assessing Libby tremolite risk using a single order of magnitude increase in toxicity over chrysotile. The writer said this conflicted with the 2 orders of magnitude and above factor observed in tremolite exposure scenarios.
  • The writer mentioned claims of a lack of money for cleanup and said the EPA continued to ignore the science on tremolite exposure and disease.
• The authors' conclusion: The writer concluded that, unless things changed drastically in Libby, its people would suffer excess mesothelioma and likely additional pleural scarring of the lungs. The writer also said Libby would be forgotten only if cleanup there was thorough.
