PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The PBT Assessment for sodium dimethyldithiocarbamate is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2017).
Persistence:
Sodium dimethyldithiocarbamate is readily biodegradable based on the available experimental data. Thus, the test substance does not meet the screening criterion for persistency and it is not considered to be persistent (P) or very persistent (vP).
Bioaccumulation:
Sodium dimethyldithiocarbamate has a log Kow of -3.2 (EU Method A.8). Thus, the substance does not meet the screening criterion for bioaccumulation and is not considered to be bioaccumulative (B) or very bioaccumulative (vB).
Toxicity:
The lowest long-term effect value for aquatic toxicity to freshwater organisms is less than 0.01 mg/L (ErC10 (72 h) = 0.74 µg a.i./L, OECD 201, N. pelliculosa). Thus, the criterion set out in Annex XIII of Regulation (EC) No. 1907/2006 is met and the test substance is considered to meet the T criterion.
In conclusion the substance is not PBT/vPvB.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
