Description of key information

In conclusion, based on the available experimental data it can be concluded that the substance is with high probability acutely not harmful for aquatic invertebrates.

Key value for chemical safety assessment

Additional information

The acute toxicity of polychloro copper phthalocyanine (CAS 1328-53-6) to aquatic invertebrates was investigated in a non GLP acute test according to Directive 84/449/EEC, C.2 using Daphnia magna. The estimated 48-h EC50 value in this study was higher than the highest tested concentration (500 mg/L), related to the nominal concentration (BASF AG 1988). The test substance was dissolved in the test water by using a vehicle (Tween 80).

Another non-GLP test according to US EPA guideline EPA-660/3-75-009 was performed. In this test no vehicle was used and the estimated 48-h EC50 was 153.6 mg/L (nominal, Union Carbide Corporation 1978)

The concentrations were not analytically verified in both studies.

In conclusion, based on the available experimental data it can be concluded that the substance is with high probability acutely not harmful for aquatic invertebrates.
