- PBT status:
- the substance is not PBT / vPvB
- Justification:
It is concluded here that the registration substance
- is not ready biodegradable and are considered to fulfil the (v)P criterion
- is not fulfilling the B (or vB) criterion
- and is not fulfilling the T criterion
and therefore is evaluated to be not PBT or vPvB substance.
- Likely routes of exposure:
The submission substance is not PBT or vPvB. Therefore no emission characterisation is required.
