PMT/vPvM Substance
Definition
PMT (Persistent, Mobile, and Toxic) and vPvM (very Persistent and very Mobile) are substance hazard categories proposed under the REACH Recast as additional SVHC criteria in Article 57. PMT/vPvM substances are particularly concerning because their mobility means they can contaminate drinking water sources at concentrations that cannot be removed by conventional water treatment. ECHA has already begun identifying PMT/vPvM substances under Article 57(f) (equivalent concern) pending the formal Article 57 amendment expected under the REACH Recast.

Practical Explanation (Compliance Context)
The PMT/vPvM framework is an emerging priority under REACH. Companies using mobile, persistent chemicals — particularly those reaching drinking water sources — should screen their substance portfolios proactively. ECHA has published PMT/vPvM assessment guidance, and formal identification of PMT/vPvM SVHCs is expected to accelerate under the REACH Recast. Early substitution planning is advisable.
