On June 25, 2025, the European Chemicals Agency (ECHA) updated the Candidate List of Substances of Very High Concern (SVHCs), adding three new substances. The total now reaches 250 substances, spanning 33 update rounds. These additions are due to concerns over very persistent, very bioaccumulative (vPvB) properties or reproductive toxicity.
