Association between cumulative fiber exposure and respiratory outcomes among Libby vermiculite workers.
To examine the association between cumulative fiber exposure and health outcomes in workers (n = 336) with Libby amphibole exposure. ⋯ The odds of several pulmonary health outcomes are correlated with cumulative exposure to Libby amphibole. That relatively low-lifetime cumulative exposures are associated with localized pleural thickening has implications for the non-cancer-risk assessment for Libby amphibole.
