PBT assessment list migrated to ECHA CHEM database

ECHA's Persistence, Bioaccumulation and Toxicity (PBT) assessment list is now available in the new ECHA CHEM database as of February 9, 2026. The PBT assessment list includes substances undergoing PBT/vPvB assessment that have been brought for discussion to ECHA's PBT Expert Group. To guarantee a smooth transition, ECHA will maintain the up-to-date list in both the legacy location and ECHA CHEM for the time being. This migration is part of ECHA's broader transition to consolidate regulatory data access in the new ECHA CHEM platform.
