- Executive summary:
The aim of the study was todetermine the EC50, LOEC and NOECof test chemical on the growth and development of embryos and larvae of the freshwater fish species zebrafish (Danio rerio) in a Fish Early-Life Stage (ELS) Toxicity Test. The study was conducted according to the OECD guideline No. 210, Adopted 26thJuly, 2013.
The test was conducted with a semi-static design with renewal once 48 h.
Concentrated stock solutions and test media were analysed during the ELS test. Based on the range finding result the definitive test was conducted with five test concentrations of 0.01, 0.03, 0.10, 0.30 and 1.00 mg/L in terms of test chemical with a conversion factor of 3.2. Both control and solvent control were included in the test design. Each concentration was divided into four replicate with 20 eggs each and including the controls.
The cumulative mortality of the control and solvent control group at 30 days post-hatch was 11.25 and 11.25 %, whereas corrected cumulative mortality of embryos, larvae and juvenile fish after at the end of exposure to test chemical at concentrations of 0.01, 0.03, 0.10, 0.30and 1.00 mg /Lwas 12.68, 28.45, 49.30, 67.61and 92.96%,respectively.
Hatching success in the control and solvent control group was 93.42 and 94.67% respectively, satisfying the validation criterion for hatching success (70%),whereas in the group treated with test chemical at concentrations of 0.01, 0.03, 0.10, 0.30and 1.00 mg/Lwas 91.18, 87.93, 67.92, 53.49and 25.00%,respectively. Fertility reduction in the group treated with test chemical at concentrations of 0.01, 0.03, 0.10, 0.30and 1.00 mg/Lwas3.69, 7.12, 28.26, 43.50 and 73.59%,respectively in comparison with the solvent control group.The NOEC and LOEC for hatching success were determined as 0.01 and 0.03 mg/L, respectively.
Larval survival until Day 30 post-hatch in the control and solvent control group was 95.0 and 93.75% thereby exceeding and satisfying the validity criteria for post-hatch survival (>75%).whereas in the group treated with test chemical at concentrations of 0.01, 0.03, 0.10, 0.30and 1.00 mg/Lwas85.0, 72.50, 66.25, 53.75 and 25.0%,respectively. Larval survival reduction in the group treated with test chemical at concentrations of 0.01, 0.03, 0.10, 0.30and 1.00 mg/Lwas 9.33, 22.67, 29.33, 42.67 and 73.33%,respectively in comparison with the solvent control group.In terms of concentrations, the NOEC and LOEC for post-hatch larval survival untilDay 30 were both considered to be equal to or less than 0.01 mg/L.
For fish total lengths, the NOEC and LOEC determined on Day 30 post-hatch were 0.01 and 0.03mg/L, respectively. For fish dry weights, the NOEC and LOEC determined on Day 30 post-hatch were 0.01 and 0.03 mg/L, respectively.
The concentrations of test chemical was determined using a validated liquid chromatographic method. Samples of each fresh test substance concentration, control and solvent control collected at exposure initiation and at renewals, and samples of each spent test substance concentration, control and solvent control collected at each renewal and at exposure termination were chemically determined.
In fresh samples of the test substance concentrations, the determined concentrations of test chemical was between 99.3 and 101.7%, concentrations, respectively. The results confirm that the test substance concentrations were within the acceptability range. In spent samples of the test substance concentrations, the determined concentrations of test chemical was between 96.1 and 96.9% of the concentrations, respectively.
All validity criteria were satisfied during the test, therefore the test was considered to be valid.
Results:The effects of test chemical on mortality, hatching success and fish larvae survivalDanio rerioin the definitive test are summarized in Table below.

Corrected mortality [%] = ((Mt - Mc) ÷ (100 - Mc)) × 100; Mt = Mortality treated, Mc = Mortality Solvent control
Description of key information
The aim of the study was todetermine the EC50, LOEC and NOECof test chemical on the growth and development of embryos and larvae of the freshwater fish species zebrafish (Danio rerio) in a Fish Early-Life Stage (ELS) Toxicity Test. The study was conducted according to the OECD guideline No. 210, Adopted 26thJuly, 2013.
The test was conducted with a semi-static design with renewal once 48 h.
Concentrated stock solutions and test media were analysed during the ELS test. Based on the range finding result the definitive test was conducted with five test concentrations of 0.01, 0.03, 0.10, 0.30 and 1.00 mg/L in terms of test chemical with a conversion factor of 3.2. Both control and solvent control were included in the test design. Each concentration was divided into four replicate with 20 eggs each and including the controls.
The cumulative mortality of the control and solvent control group at 30 days post-hatch was 11.25 and 11.25 %, whereas corrected cumulative mortality of embryos, larvae and juvenile fish after at the end of exposure to test chemical at concentrations of 0.01, 0.03, 0.10, 0.30and 1.00 mg /Lwas 12.68, 28.45, 49.30, 67.61and 92.96%,respectively.
Hatching success in the control and solvent control group was 93.42 and 94.67% respectively, satisfying the validation criterion for hatching success (70%),whereas in the group treated with test chemical at concentrations of 0.01, 0.03, 0.10, 0.30and 1.00 mg/Lwas 91.18, 87.93, 67.92, 53.49and 25.00%,respectively. Fertility reduction in the group treated with test chemical at concentrations of 0.01, 0.03, 0.10, 0.30and 1.00 mg/Lwas3.69, 7.12, 28.26, 43.50 and 73.59%,respectively in comparison with the solvent control group.The NOEC and LOEC for hatching success were determined as 0.01 and 0.03 mg/L, respectively.
Larval survival until Day 30 post-hatch in the control and solvent control group was 95.0 and 93.75% thereby exceeding and satisfying the validity criteria for post-hatch survival (>75%).whereas in the group treated with test chemical at concentrations of 0.01, 0.03, 0.10, 0.30and 1.00 mg/Lwas85.0, 72.50, 66.25, 53.75 and 25.0%,respectively. Larval survival reduction in the group treated with test chemical at concentrations of 0.01, 0.03, 0.10, 0.30and 1.00 mg/Lwas 9.33, 22.67, 29.33, 42.67 and 73.33%,respectively in comparison with the solvent control group.In terms of concentrations, the NOEC and LOEC for post-hatch larval survival untilDay 30 were both considered to be equal to or less than 0.01 mg/L.
For fish total lengths, the NOEC and LOEC determined on Day 30 post-hatch were 0.01 and 0.03mg/L, respectively. For fish dry weights, the NOEC and LOEC determined on Day 30 post-hatch were 0.01 and 0.03 mg/L, respectively.
The concentrations of test chemical was determined using a validated liquid chromatographic method. Samples of each fresh test substance concentration, control and solvent control collected at exposure initiation and at renewals, and samples of each spent test substance concentration, control and solvent control collected at each renewal and at exposure termination were chemically determined.
In fresh samples of the test substance concentrations, the determined concentrations of test chemical was between 99.3 and 101.7%, concentrations, respectively. The results confirm that the test substance concentrations were within the acceptability range. In spent samples of the test substance concentrations, the determined concentrations of test chemical was between 96.1 and 96.9% of the concentrations, respectively.
All validity criteria were satisfied during the test, therefore the test was considered to be valid.

Additional information
The aim of the study was todetermine the EC50, LOEC and NOECof test chemical on the growth and development of embryos and larvae of the freshwater fish species zebrafish (Danio rerio) in a Fish Early-Life Stage (ELS) Toxicity Test. The study was conducted according to the OECD guideline No. 210, Adopted 26thJuly, 2013.
The test was conducted with a semi-static design with renewal once 48 h.
Concentrated stock solutions and test media were analysed during the ELS test. Based on the range finding result the definitive test was conducted with five test concentrations of 0.01, 0.03, 0.10, 0.30 and 1.00 mg/L in terms of test chemical with a conversion factor of 3.2. Both control and solvent control were included in the test design. Each concentration was divided into four replicate with 20 eggs each and including the controls.
