Study on asbestos-related diseases in Libby launched
July 09, 2017
Health effects have been detected not just in mine and processing plant workers, area lumber mill workers and loggers (from asbestos dusting of forests) and their families, but also among other Libby residents and their children. Many were exposed through ambient air or to mine tailings and other contaminated materials provided to the town by mining companies for the construction of ball fields, school running tracks, playgrounds, public buildings and facilities, as well as for private gardens and house and business insulation.
There is evidence that even relatively low-level exposures to Libby asbestos can cause serious scarring lung diseases, which markedly impair respiratory function, as well as asbestos-related cancers like lung cancer and mesothelioma, which occur at higher rates among the Libby population than elsewhere in the United States.
The health crisis potentially extends far beyond the borders of Libby, since millions of homes and businesses in North America have used vermiculite from Libby as attic insulation, fireproofing and soil conditioner. The ore from Libby was shipped by rail to 49 plant locations throughout North America and the Caribbean for processing, exposing many more workers and communities to the hazardous dust.
CARD Director Brad Black, MD, said, "The pattern of asbestos disease caused by exposure to Libby amphibole asbestos has led to excessive morbidity and mortality for the Libby population, and has been exceedingly challenging for the medical community. The severity of nonmalignant pulmonary disease in non-occupational exposure has been very unusual, raising question as to the potency of the unique amphibole mixture. We look forward to working with Dr. Levin and Mount Sinai to find some of these answers."
