- Details on sampling:
- The confirmatory chemical analysis was based on the concentration of the fatty acid component (azelate) and on the concentration of the lithium ion. The concentration of total organic carbon (TOC) was also measured.
Samples for analysis were taken from the control and the 100 mg/L treatment at the start of the test and after 96 hours of exposure and stored in a refrigerator (TOC) or freezer (lithium and azelate) until analysis.
For the determination of the test substance based on azelate, the samples were diluted in a 1:1 (v:v) ratio with 2% formic acid in acetonitrile and analysed. If necessary, the samples were further diluted with 1% formic acid in 50/50 (v/v) acetonitrile/ISO-medium to obtain concentrations within the calibration range.
For the determination of the test substance based on lithium the samples were diluted in a 24:1 (v:v) ratio with HNO3 and analysed. If necessary, the samples were further diluted with 4% HNO3 in ISO-medium to obtain concentrations within the calibration range. - Vehicle:

- Details on test solutions:
- - Solution: Adjusted ISO medium
- Solubility: The test item was completely soluble in test medium at the concentrations tested.
- Preparation of test solutions: A solution with a concentration of 100 mg/L was prepared by vigorous shaking to completely dissolve test substance in test medium.
- Appearance: The solutions were clear and colourless at test start. The controls remained clear and colourless during the test. The test solution was hazy from 72 hours and at the end of the test a floating layer and precipitate were observed. - Test organisms (species):

OTHER TEST CONDITIONS
- Photoperiod: 16 hours
- Feeding: None from 24 hours prior to test start
- Observations: 2.25, 24, 48, 72 and 96 hours for mortality and other effects - Reference substance (positive control):
- yes
- Remarks:
- pentachlorophenol (PCP)
- Duration:
- 96 h
- Dose descriptor:
- LC50
- Effect conc.:
- > 100 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mortality (fish)
- Details on results:
- No LC50 could be calculated because it exceeded the maximum concentration tested (LC50 >100 mg/L).
- Results with reference substance (positive control):
- The 96h-LC50 for carp exposed to PCP was 0.32 mg/L. The range of the 96h-LC50 for carp is generally between 0.10 and 0.46 mg/L. Hence, the sensitivity of carp originating from the present batch for PCP falls within the range of sensitivities generally observed during the past years.
- Reported statistics and error estimates:
- No data reported.
- Validity criteria fulfilled:
- yes
- Remarks:
- No mortality in control, test conditions were constant, dissolved oxygen >5 mg/L, measured concentrations at least 80% of nominal
- Conclusions:
- No LC50 could be calculated because it exceeded the maximum concentration tested (LC50 > 100 mg/L).
- Executive summary:
The effect of dilithium azelate on the mortality of the carp (Cyprius carpio) was investigated according to an OECD 203 guideline and EC method C1. A 96 hour limit test at 100 mg/L was conducted under static conditions. At the start of the test all solutions were clear and colourless. The test solution was hazy from 72 hours and at the end of the test a floating layer and precipitate was observed. Analysis of the fatty acid (azelate) was between 81 and 90% nominal and the lithium concentration was 117% of nominal throughout the test. The total organic carbon (TOC) measured at the start of the test was 59 mg/L and at the end of the test was 51 mg/L. The test concentrations were considered to be maintained and the results are reported based on nominal concentrations. The study met all the validity criteria for the test. As no fish mortalities were observed in the test the LC50 is > 100 mg/L dilithium azelate.

Description of key information
The LC50 values are > 100 mg/L for dilthium azelate and for reaction mixture of hydrogenated tallow alkyl amines with sebacic acid and calcium hydroxide.
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 100 mg/L
Additional information
No data on acute toxicity to fish is available for the substance, reaction mass of amines, hydrogenated tallow alkyl and azelaic acid and lithium hydroxide. Therefore, the endpoint is completed with data on dilithium azelate and on reaction product of hydrogenated tallow alkyl amines with sebacic acid and calcium hydroxide.
Two key studies conducted with read across substances, dilithium azelate and reaction mixture of hydrogenated tallow alkyl amines with sebacic acid and calcium hydroxide are available for this endpoint. No effects on the fish mortality were observed in both studies, therefore it was concluded that the LC50 values are > 100 mg/L for dilthium azelate and for reaction mixture of hydrogenated tallow alkyl amines with sebacic acid and calcium hydroxide.
The studies were conducted according to o an OECD 203 guideline and EC method C1 and are GLP-compliant, therefore are considered reliable and suitable for this endpoint.
