Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB

As the substance is inorganic, according to ECHA Guidance on Information Requirements and CSA, R.11, the PBT and vPvB criteria of Annex XIII do not apply. The organic component of the complexed submission substance, humic acid potassium salt, which is contained in the complex at a concentration <1%, is a naturally occuring substance and of low lipophilicity, with a logPow of < 2.5.

In addition, molecular size is considerable with approximately 5000 g/mol. According to REACH guidance R.11, a molecular weight higher than 1100 g/mol is an indicator that the aquatic BCF of the respective substance is lower than 2000 L/kg. Thus, the molecular weight of the humic acid potassium salt being far above the threshold value of 1100 g/mol strongly indicates low bioconcentration potential.

Likely routes of exposure:

As the submission substance is not PBT or vPvB, no exposure assessment is necessary.
