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

 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 anhydrideis 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

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.Succinic anhydride is neither a PBT nor a vPvB substance.
