Description of key information
No data on long-term toxicity on aquatic invertebrates are available.
Key value for chemical safety assessment
Additional information
No long-term studies for the toxicity of 'zinc phthalocyanine sulfonate' on fish and aquatic invertebrates are available. In Annex IX of Regulation (EC) No 1907/2006, it is laid down that chronic tests shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects on fish or aquatic invertebrates. It was proven with an exposure estimation, that all identified uses of the substance are safe (RCR < 1). Furthermore the substance is with high probability acutely not harmful to fish and invertebrates. Otherwise 'zinc phthalocyanine sulfonate' can cause toxic effects to aquatic green algae. Hence algae turned out to be the most sensitive trophic level. Therefore, the chemical safety assessment based on the investigations with aquatic algae. It can be assumed that long-term tests with fish and aquatic invertebrates would not reveal any different findings. Therefore, and for reasons of animal welfare long-term tests on fish as well as on aquatic invertebrates are not required.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
