Administrative data

PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB
Justification:

Hydrogen fluoride is concluded to be not PBT or vPvB based on available data.

Persistence

Hydrogen fluoride is a simple inorganic substance and is therefore not subject to biodegradation, but instead rapidly dissociates at environmentally relevant pH to form hydrogen and fluoride ions, both of which are ubiquitous in the environment. It is therefore concluded that hydrogen fluoride has no potential to persist and is not considered P/vP.

Bioaccumulation

Available data show that fluoride has low bioaccumulation potential, with no accumulation reported for edible tissue. It is therefore concluded that hydrogen fluoride does not meet the criteria to be considered B/vB.

Toxicity

Available long-term toxicity data for freshwater fish, Daphnia and algae exposed to fluoride all report NOEC values >0.01 mg/L. It is therefore concluded that hydrogen fluoride does not meet the criteria to be considered T from an environmental perspective.
