- PREPARATION AND APPLICATION OF TEST SOLUTION (especially for difficult test substances)
Test Concentration:
A water soluble fraction of the test item, prepared as a filtrate of a suspension containing 100 mg /L of the test item, and a control.
Control:
In the control, test water was used without addition of the test item.
Dosage of Test Item:
The test item is not easily soluble in test water. To avoid physical effects of undissolved test item on the Daphnia, no concentration above the solubility limit of the test item in test water was tested. Therefore, a nominal loading rate of 100 mg test item/L was prepared by suspending 40.9 mg of test item in 409 mL test water. This suspension was stirred for 24 hours in the dark to dissolve as much test item as possible. Then, the undissolved test item was separated by filtration (0.45 µm cellulose nitrate filter) and the resulting water soluble fraction was used as test medium. The test medium was prepared just before introduction of the Daphnia (= start of the test). - Test organisms (species):

Description of key information
With high probability acutely not harmful to aquatic invertebrates
Key value for chemical safety assessment
Additional information
There are no studies available that assess the acute toxicity of the test substance to aquatic invertebrates. However, as the test substance belongs to the substance group of Phthalocyanines whose group members resemble in their chemical structure as well as in their phys-chem properties, a read-across approach was used to cover this endpoint.
The toxicity of Phthalocyanines to Daphnia magna was tested by guideline studies conducted with the analogue substances CAS 59160-79-1, and CAS 147-14-8.
The toxicity of CAS 59160 -79 -1 to the freshwater invertebrate Daphnia magna was assessed in a study following OECD 202 with static test design and analytical monitoring. An EC50 > 100 mg/L was identified in this study after 48 h of exposure [Ibacon 2015].
The toxicity of CAS 147-14-8 to Daphnia magna was tested in a study following EU Directive 79/831/EEC. The animals were exposed to the test substance for 48 hours and an EC50 > 500 mg/l was determined [BASF AG 1989]. However, a solubilizer was used in this test.
