PBT assessment

Administrative data

PBT assessment: overall result

Reference
Name:
Methyl dihydrogen phosphate
Type of composition:
legal entity composition of the substance
State / form:
liquid
Reference substance:
Methyl dihydrogen phosphate
Reference substance:
Methyl dihydrogen phosphate
PBT status:
the substance is not PBT / vPvB
Justification:

Persistence

 

Not P or vP

 

The substance is readily biodegradable and will not persist in the environment.

Bioaccumulation

 

Not B or vB

 

Bioconcentration factor (BCF) for the registered substance is predicted to be 3.162 L/kg wet weight and, in accordance with ECHA guidance on Information Requirements and Chemical Safety Assessment Chapter R.11: PBT/vPvB assessment (Version 3.0; June 2017), bioaccumulation is not expected when the aquatic BCF of a substance is < 2000 L/kg.

Toxicity

 

Potentially T

Based on available evidence, and in accordance with Regulation (EC) No. 1272/2008, the registered substance does not meet the criteria for classification as a carcinogen (category 1A or 1B), germ cell mutagen (category 1A or 1B) or reproductive toxin (category 1A, 1B or 2).Furthermore, there is no evidence of chronic toxicity and the substance does not meet the criteria for classification for specific target organ toxicity (STOT RE 1 or STOT RE 2).With respect to the environment,short-term freshwater toxicity results are available for three trophic levels (fish, Daphnia and algae) Since no aquatic toxicity was reported at the concentration tested in any of the studies, it is considered unlikely that the registered substance will meet the T criterion. Nevertheless, the available acute data are considered screening information and cannot be used to definitively conclude not T even though the substance is not classified as environmentally hazardous (see ECHA guidance on Information Requirements and Chemical Safety Assessment Chapter R.11: PBT/vPvB assessment; Version 3.0, June 2017).
