Succinic anhydride

PBT assessment

PBT assessment: overall result

Reference

Name:

Succinic anhydride

Type of composition:

boundary composition of the substance

State / form:

solid: particulate/powder

Reference substance:

Succinic anhydride

PBT status:

the substance is not PBT / vPvB

Justification:

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

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 below.  The vP and the vB criterion are not fulfilled.

Succinic anhydride is neither a PBT nor a vPvB substance.

Criterion	PBT criteria	vPvB criteria	Succinic anhydride	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	Succinic anhydride is readily biodegradable and therefore has no potential to persist.	no
B	BCF > 2000	BCF > 5000	Succinic anhydridehas low potential to bioaccumulate based on a log Kow of 2.44.	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, succinic anhydride 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	n.a.	Not classified as T, R48, or Xn, R48 according to Directive 67/548/EEC	no
