PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB

Conclusion on persistence:

The half lives of cloquintocet-mexyl in soil and water/sediment systems are well below the threshold criteria in accordance with Annex XIII, thus indicating a non-persistent substance (not P or vP).

Conclusion on bioaccumulation:

Based on measured data from a fish bioconcentration study, the whole fish BCF was 621, significantly lower than the threshold of concern of 2000. Cloquintocet-mexyl is, therefore, not bioaccumulative (not B or vB).

Conclusion on toxicity:

The NOEC, from recognised long-term toxicity studies with aquatic organisms, ranges from 0.09 mg/L (algae) to 0.437 mg/L (invertebrates). In all cases, the NOEC values are >0.01 mg/L. Therefore, cloquintocet-mexyl does not fulfil the toxicity criterion (not T).

Likely routes of exposure:

Not applicable.
