PBT assessment: overall result

Reference
Name:
Dibenzetano
Type of composition:
legal entity composition of the substance
State / form:
solid: particulate/powder
Reference substance:
Dibenzetano
PBT status:
the substance is handled as if it were a PBT/vPvB
Justification:

According to the results of the Biodegradation test (in read-across from DPX-C), Dibenzetano is not readily biodegradable. QSAR results support this conclusion. No Hydrolysis test could be performed becaouse the substance is not soluble in water. Therefore the criteria for Persistence (P) are expected to be met. Available data does not permit the classification as very Persistent (vP).

 

No bioaccumulation data on fish are available for Dibenzetano, but, according to the logPOWand toxicokinetics considerations, it is expected to bioaccumulate in living organisms. Therefore, from a precautionary point of view, criteria for classification as Bioaccumulative (B) are met. Available data does not permit the classification as very Bioaccumulative (vB).

 

According to the 28-day repeated dose toxicity study by oral route in rats (in read-across from DPX-C), the substance is classified as STOT RE 2, H373. Therefore the criteria for the classification as Toxic (T) are met.
