Description of key information
Additional information
For 'zinc phthalocyanine sulfonate' acute aquatic toxicity data on all three trophic levels are available. This includes one study for toxicity on the zebrafish Danio rerio, one study on the immobilization of the waterflea Daphnia magna, one study on the mortality of the pink shrimp Penaeus duorarum and two studies of the toxicity on the green algae Desmodesmus subspicatus and Pseudokirchneriella supcapitata.
Effects on fish and aquatic invertebrates occur only at very high concentrations of ‘zinc phthalocyanine sulfonate’. The detected EC/LC50 values for fish and invertebrates are at concentrations above 100 mg/L test item. In contrast the EC50(72h) on growth inhibition of green algae is reported with 4.57 mg/L test item. This result is used for the PNEC derivation.
Obviously the impact of ‘zinc phthalocyanine sulfonate’ on green algae is considerable higher than those on other aquatic organisms. Therefore, it can be expected that the toxicity on algae is based on a specific mechanism. Phthalocyanine are aromatic complexes, which are structurally related to porphyrins, such as the cytochromes of the photosynthesis. Equal to the photosynthesis pigments, the phthalocynines are colored green-blue, due to adsorption of light with a wavelength between 600 and 700 nm. Therefore phthalocyanine compete for the light energy.
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. Since ‘zinc phthalocyanine sulfonate’ is with high probability acutely not harmful to fish and invertebrates long-term tests are not required. For aquatic green algae, which represents the most sensitive trophic level, an ErC10(72h) of 1.07 mg/L is reported.
