Description of key information

With high probability acutely not harmful to aquatic algae.

Key value for chemical safety assessment

Additional information

The toxicity to aquatic algae 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. Aquatic algae toxicity data are available for different members of the category. In all studies no effects were observed up to the limit of water solubility of the tested substances. Based on this information no key value for assessment can be determined. The substance is however assessed to be with high probability acutely not harmful to aquatic organisms.
