Name:
1,3,4-thiadiazole-2,5-dithiol
Type of composition:
legal entity composition of the substance
Reference substance:
Composition 1
PBT status:
the substance is not PBT / vPvB
Justification:

Data for a definitive conclusion on the PBT or vPvB properties of the substance are not available. Thus, the screening criteria given in the „Guidance on information requirements and chemical safety assessment, chapter R.11: PBT assessment‟ (ECHA, 2008) are used as surrogate information to decide whether the substance may potentially fulfill the PBT or vPvB criteria.

Based on the available data on biotic and abiotic degradation, bioaccumulation and toxicity, the substance fulfills the screening criterion for persistence may be potentially P and vP, but neither of the constituents fulfills the criteria for B and vB and T.

As the criteria for toxicity and bioaccumulation are not fulfilled it is not a PBT or vPvB substance. No emission characterisation is performed.
