HEALTH EFFECTS
Most researchers have found that the chances that asbestos exposure will lead to lung cancer depends not only on the cumulative dose of asbestos, but also on ... PBPK/PD models refine our understanding of complex quantitative dose behaviors by helping to delineate and characterize the relationships between: (1) the external/exposure ...
HEALTH EFFECTS
Levels of exposure associated with carcinogenic effects (Cancer Effect Levels, CELs) of asbestos are indicated in Tables 3-1, 3-2, and 3-3 and Figures 3-1, 3-2 and 3-3.
Libby Amphibole Asbestos Plain Language Frequent …
This IRIS assessment addresses the potential cancer and noncancer human health effects from inhalation exposure to Libby Amphibole asbestos (LAA). The noncancer findings of this assessment concluded that exposure to LAA may cause thickening of the pleura. The pleura are the membranes that envelop the lungs and line the chest cavity.
