Description of key information

With high probability not toxic to sediment.

Key value for chemical safety assessment

Additional information

The toxicity to sediment is assessed based on a category approach. The category members are composed of a structurally analogue organic part but different metals that are laked with the organic structure. At environmentally relevant pH values disintegration of the molucule and a release of the metal component is not expected. Therefore an influence of the laked metal part is not expected. Sediment toxicity data are available for one member of the category. The 28-d NOEC is 1000  mg/kg dw.
