TEST CONCENTRATIONS
- Range finding study:
* Test concentrations: 1.0, 10 and 100% of a SS prepared at 100 mg/L (3 fish/concentration)
- Results used to determine the conditions for the definitive study: No mortality or clinical effects were observed at any of the test concentrations during the test period.- Reference substance (positive control):
- yes
- Remarks:
- Pentachlorophenol (Feb 2017)
- Key result
- Duration:
- 96 h
- Dose descriptor:

- Basis for effect:
- mortality (fish)
- Remarks on result:
- other: LC50 is considered to be above the maximum solubility of the test item in test medium
- Details on results:
- No mortality or clinical effects were observed at both the SS and the control during the test period (see Table 2 in "Any other information on results incl. tables". The responses recorded in the SS were in agreement with the results of the range-finding test.

- - Results with reference substance valid? Yes
- The 96h-LC50 for carp exposed to PCP was 0.32 mg/L (95 % confidence interval between 0.22 and 0.46 mg/L). This is within the range of sensitivities generally observed during the past 30 years (0.10 - 0.46 mg/L)- Sublethal observations / clinical signs:

- Conclusions:
- An acute fish study was performed with Pigment Red 63:1 according to OECD guideline 203 and GLP principles. Actual test concentrations could not be measured during the test. Therefore, the LOQ of 0.010 mg/L was considered to be above the maximum solubility limit of Pigment Red 63:1 in test medium. Due to the low solubility of C.I. Pigment Red 63:1 in water, concentration levels that might be lethal to carp could not be reached. Therefore, the LC50 was considered to be above the maximum solubility of Pigment Red 63:1 in test medium at all time points during the 96h test period.
- Executive summary:
In a 96 -h OECD 203 study according to GLP principles, the acute toxicity of the test substance to carp (Cyprinus carpio) was investigated. A final test was performed based on the results of a preceding range-finding test. Seven carp per test group were exposed to an untreated control and to a saturated solution prepared at 100 mg/L. No mortality or clinical effects were observed at both the SS and the control during the test period. Samples taken from the SS were analysed and showed that the measured concentrations were below the limit of quantification (LOQ was 0.010 mg/L) throughout the test period. Due to the low solubility of the test substance, the LC50 is considered to be above the maximum solubility of the test substance in test medium. The study is considered to be valid.
