PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB
Justification:

The percentage of biodegradation of MES reached 92 % of the ThOD after 31 days with adapted bacteria (enhanced ready biodegradation test). Thus MES was determined to be not P/vP in the environment. In addition, MES has a low potential for bioaccumulation and is not B/vB. Therefore, it is not considered PBT or vPvB.
