- PREPARATION AND APPLICATION OF TEST SOLUTION
A defined amount of the test item was added directly to the test water for each test concentration and was carefully stirred for 24 hours at room temperature in the dark to dissolve as much of the test item as possible. The highest test item concentration of 100 mg test item/L was prepared by mixing 100.8 mg test item into 1008 mL test water, for the test item concentration of 33.3 mg test item/L, 33.0 mg test item were mixed into 991 mL test water, for the concentration of 11.1 mg test item/L, 10.8 mg were mixed into 973 mL test water. The concentration of 3.7 mg test item/L was prepared by mixing 3.6 mg into 973 mL test water and for 1.2 mg test item/L, 3.6 mg were mixed into 3000 mL test water. Then, the undissolved test item was separated by filtration (0.45 μm cellulose acetate filter) and the filtrates were used as test concentrations. The test concentrations were prepared just before introduction of the Lemna (= start of the test). - Test organisms (species):

Description of key information
EC50/EC10(7d) > 100 mg/L for frond number of Lemna minor (OECD 221, read across)
Key value for chemical safety assessment
Additional information
No data is available for the substance itself. Therefore, data from the following two close structural analogues are used as part of a weight of evidence approach: Pigment Additive PAG (CAS 28901-96-4) and phthalocyanine with SO3Na groups on rest group 1 and 2 and an H-atom on rest group 3 and 4.
The toxicity towards freshwater aquatic plants was determined for the substance Pigment Additive PAG (CAS 280901-96-4) in a study according to OECD 221 and in compliance with GLP criteria (BASF 2015). In this study, duckweed (Lemna gibba) was exposed to water soluble fractions of nominal loadings of 0 (control), 1.2, 3.7, 11.1, 33.3 and 100 mg/L for 7 days under static conditions. Test concentrations were analytically verified at the start and the end of exposure, based on carbon content. These measured values were uniform over time and thus effect values are reported as nominal concentrations. At days 3, 5 and 7 frond numbers and appearance of colonies were observed. Additionally, at the test start the dry weight of a sample of fronds identical to those used to inoculate the test vessels was determined and at the end of the test the dry weight of all plants from each vessel was determined. The 7-d EC50 values for growth rate (ErC50) and yield (biomass, EyC50) based on frond number were determined at >100 mg/L (based on either frond number or dry weight). The 7-d ErC10 was determined to be >100 mg/L (based on either frond number or dry weight) and the 7-d EyC10 values were 48.2 and 88.3 mg/L considering biomass frond number and dry weight, respectively.
Additionally, the toxicity towards freshwater aquatic plants was determined for phthalocyanine (R1,2 =SO3Na, R3,4 = H) in a bioassay that was designed according to ISO 20079 (Jancula, 2012). In this study, duckweed (Lemna minor) was exposed to nominal concentrations of 0 (control), 6.25, 12.5, 25 and 50 mg/L for 7 days under static conditions. Test concentrations were not analytically verified. At day 7 the frond numbers, root length and dry weight were determined. The 7-d EC50 values for frond number, root length and dry weight were >50 mg/L, 43.69 ± 6.42 mg/L and 40.77 ± 3.33 mg/L, respectively.
No effect on (the growth rate of) frond numbers was observed. Based on the close resemblance between the structural analogues and the target substance, its E(r)C50 is also assumed to be >50 mg/L. Overall, no effects on growth were observed up to the limit of water solubility and thus the substance is not considered to be harmful to aquatic plants other than algae.
