OEHHA Publishes Prop 65 Definition of Nickel (Soluble Compounds)

On May 2, 2019, California’s Office of Environmental Health Hazard Assessment (OEHHA) published a definition of nickel (soluble compounds) for the purposes of Proposition 65 (Prop 65). Under the notice, nickel (soluble compounds) are defined to be compounds of nickel with solubility in water of greater than 0.1 moles per liter (mol/L) at 20oC. OEHHA states that this definition is consistent both with the discussion by the Developmental and Reproductive Toxicant Identification Committee (DARTIC) that led to the listing of nickel (soluble compounds) and OEHHA’s prior definition of soluble nickel compounds in the 2012 document, “Nickel Reference Exposure Levels: Nickel and Nickel Compounds. Nickel Oxide. Reference Exposure Levels (RELs).”  Bergeson & Campbell
