br Mounting evidence of the health
Mounting evidence of the health impacts of Libby asbestos in ex-posed communities such as Libby, Montana and Northeast Minneapolis, MN, makes a case for active intervention by public health practitioners to educate the public and promote safe removal of vermiculite attic insulation by asbestos abatement contractors in all communities.
Our analysis provides further evidence that low-dose Protease Inhibitor Cocktail exposure to Libby amphibole asbestos from a neighborhood vermiculite processing plant is associated with increased asbestos-related disease and mortality. Even when accounting for possible occupational asbestos exposure, we observed significant excess mesothelioma and lung cancer deaths in females. Lung cancer incidence was significantly elevated in both genders, even after adjusting for an overall cancer deficit, and deaths from all respiratory cancers combined were elevated in both genders.
Given that mesothelioma rates are not declining in women, future research should continue to focus on the effects of low-level, non-oc-cupational sources of asbestos exposure. This includes investigating the Environmental Research 175 (2019) 449–456
possible health impacts and prevalence of ongoing residential exposure to vermiculite attic insulation. It is essential to consider the impact of smoking by examining interactions of smoking and asbestos exposure. In this Minneapolis community cohort, continued clinical follow-up and surveillance are warranted to assess latent respiratory disease.
