Endpoint:
additional information on environmental fate and behaviour
Type of information:
migrated information: read-across based on grouping of substances (category approach)
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
results reported were all obtained under conditions relevant for setting the partition coefficient for zinc in marine waters; The chemical safety assessment of zinc potassium chromate is based on elemental zinc and chromate concentrations and read across to zinc and chromate substances. Justification for read across from Zn and Cr(III) is provided in the endpoint summary section.
