PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- Aminoiminomethanesulphinic acid
- Type of composition:
- legal entity composition of the substance
- State / form:
- solid: bulk
- Reference substance:
- Aminoiminomethanesulphinic acid
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The PBT Assessment for aminoiminomethanesulphinic acid (CAS No. 1758-73-2)is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2012).
Persistence
Aminoiminomethanesulphinic acid is readily biodegradable in one study according to OECD 301C (80.6% (BOD) after 28 d). Thus, the test substance does not meet the screening criterion for persistency and it is not considered to be P or vP.
Bioaccumulation
Aminoiminomethanesulphinic acid has a log Kow of -3.83 (KOWWIN v1.68) indicating a low potential for bioaccumulation. Thus, the test substance does not meet the screening criterion for bioaccumulation and it is not considered to be B or vB.
Toxicity
The substance is classified as H373 ("May cause damage to organs through prolonged or repeated exposure"). Thus, the substance meets the criteria set out in Annex XIII of Regulation (EC) No 1907/2006 and fulfills the toxicity criterion.
Conclusion
In conclusion the substance is not considered to meet the criteria to be classified as PBT or vPvB based on the available data.
