PBT assessment

Currently viewing:

Administrative data

PBT assessment: overall result

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

L-aspartic acid is readily biodegradable and has no bioaccumulation potential.

 Criterion

PBT criteria

vPvB criteria

L-Aspartic acid

 Criterion fulfilled?

 P

Half-life in marine water > 60 d, or half-life in fresh- or estuarine water > 40 d, or half-life in marine sediment > 180 d, or half-life in fresh- or estuarine water sediment > 120 d, or half-life in soil > 120 d

Half-life in marine, fresh or esturarine water > 60 d, or Half-life in marine, fresh or esturarine sediment > 180 d, or half-life in soil > 180 d

 

L-Aspartic acid is readily biodegradable and therefore has no potential to persist.

 

 no

 B

 BCF > 2000

 BCF > 5000

L-Aspartic acid has low potential to bioaccumulate based on a log Kow of-3.89.

 no

 T

Long-term NOEC for marine or freshwater organisms < 0.01 mg/l

 

No long term data.

 no

 T

 CMR

 n. a.

On the basis of the hazard assessment, L-Aspartic acid is not expected to be carcinogenic, mutagenic or a reproductive toxicant.

 no

 T

Other evidence of chronic toxicity, as identified by the classifications: T, R48, or Xn, R48 according to Directive 67/548/EEC and Not classified as STOT RE category 1 or 2 according to Regulation EC 1272/2008 (CLP)

 n. a.

Not classified as T, R48, or Xn, R48 according to Directive 67/548/EEC and

Not classified as STOT RE category 1 or 2 according to Regulation EC 1272/2008 (CLP)

 

 no

Overall conclusion:

Based on the assessment described in the subsections above the submission substance is not a PBT / vPvB substance.

A substance is identified as a PBT substance if it fulfils all three PBT criteria described above.

None of these criteria are fulfilled and therefore Succinic anhydride cannot be classified as PBT.

A substance is identified as a vPvB substance if it fulfils both vPvB criteria described above.  

The vP and the vB criterion are not fulfilled. L-Aspartic acid is neither a PBT nor a vPvB substance.Accordingly, an Emission Characterisation under Section 4.2 of Annex I is not required
