PBT status:

the substance is not PBT / vPvB

Justification:

Based on evaluation of the data described in the endpoint it is concluded here that the members of the Naphtol-AS Pigment category

·   are not inherently (and thus also not readily) biodegradable and are considered to fulfil the P criterion

·   are not fulfilling the B (or vB) criterion

·   and are not fulfilling the T criterion

and therefore are evaluated to be neither PBT nor vPvB substances.

Overall conclusion:

Based on the assessment described the submission substances of the category of Naphtol-AS Pigments are not considered to be PBT /vPvB.

Likely routes of exposure:

The submission substances are not PBT or vPvB. Therefore no emission characterisation is required.
