Probabilistic Assessment of the Relative Source Contribution Factor While Accounting for Exposure to Other Regulated Media: A Toxicokinetic Proof-of-Concept for Volatile Drinking Water Contaminants.
A relative source contribution factor is applied when deriving noncancer health-based guidance values for drinking water contaminants. The present work aimed at assessing the adequacy of the 20% default value often attributed to this factor while accounting for concomitant inhalation exposure to the reference concentra...
