Vanadium is a transition metal that occurs naturally in Earth’s crust. Fossil fuel combustion is thought to be the major anthropogenic source of vanadium to the atmosphere. The use of heavy oils and bitumen from tar sands and the use of vanadium in industrial applications (e.g., steel production, vanadium redox-flow batteries, and catalytic converters) can contribute to the release of vanadium into the environment.
|May 2021||EPA released the IRIS Assessment Plan (IAP) for Inhalation Exposure to Vanadium and Compounds for a 30-day public comment period. [Federal Register Notice May 28, 2021]|
Following the public (webinar) meeting, the IRIS Program will use the IAP to inform the subsequent development of a chemical-specific systematic review protocol.
