- Details on test solutions:
- PREPARATION AND APPLICATION OF TEST SOLUTION (especially for difficult test substances)
- Method: A stock-solution was prepared by mixing the test substance in the dilution water. The stock solution was continually dispensed and diluted with dilution water using the respective equipment to deliver a series of five concentrations at the same time to the corresponding test vessels.
- Controls: Dilution water only - Test organisms (species):
- Oncorhynchus mykiss (previous name: Salmo gairdneri)
- Details on test organisms:
- TEST ORGANISM
- Common name: rainbow trout
- Source: Eye point stage eggs were obtained from the NRW Landesanstalt für Fischerei (governmental fisheries agency), Albaum, Germany on March 22, 2007 and further bred in the test facility.
- Length and weight at study initiation: 5 cm ± 1 cm; 3 g ± 1 g
- Method of breeding: Rainbow trout fingerlings were bred at 12.0 °C under flowthrough conditions in the laboratory of the Fh-IME. During the week the trouts were fed daily with commercial food. Larvae were fed daily ad libitum from the day of the first swim-up with pulverized trout food (Trouvit Alleinfuttermittel, Milkivit, D86664 Burgheim). From day 17 on, crushed trout food was given.
Only fish without visible abnormalities were used in the study.
FEEDING DURING TEST
- Food type: Trout food (Trouvit Alleinfuttermittel, Milkivit, D- 86664 Burgheim)
- Amount: All fish were weighed before test start. A feeding rate of 4 % of body weight was adjusted, divided into two equal portions per day.
The fish were weighed again on day 14 of the test to recalculate and adjust the feeding rate, and on day 28 to obtain the results of growth.
- Frequency: Twice per day - Test type:
- flow-through
- Water media type:
- freshwater
- Limit test:
- no
- Total exposure duration:
- 28 d
- Test temperature:
- 13.3–14.9 °C
- pH:
- 7.5–8.1
- Dissolved oxygen:
- 65–98 %
- Nominal and measured concentrations:
- Nominal: 23.5, 42.0, 93.5, 188 and 375 μg/L (corresponding to nominal concentrations of 4.7, 9.4, 18.8, 37.5 and 75.0 μg active substance/L)
Due to a complete lack of adverse effects on juvenile growth, only the two highest test item concentrations (37.5 and 75 μg/L, nominal) were verified analytically.
The arithmetic means of the measured concentrations of the four lead compounds were extrapolated to the total content of active substance.
The recovery rate at 37.5 μg a.s./L (nominal) was 36.3 %, thus resulting in an actual test item concentration of 13.6 µg a.s./L.
At a nominal test item concentration of 75 μg a.s./L, 69.7 % of the lead compounds were recovered, corresponding to 52.3 µg a.s./L. - Details on test conditions:
- TEST SYSTEM
- Type: open
- Material, fill volume: glass aquaria, 25 L
- Aeration: yes
- Renewal rate of test solution: Flow rate of about 2.5 L/h (daily turnover of about 5 volumes)
- No. of organisms per vessel: 10
- No. of vessels per concentration (replicates): 2
- No. of vessels per control (replicates): 2
- Biomass loading rate: < 2.0 g fish wet weight/L
TEST MEDIUM / WATER PARAMETERS

EFFECT PARAMETERS MEASURED:
Behaviour and mortality: Daily
Weight and length: Test start and after 14 days and 28 days
Analytical samples: Test start and days 7, 14, 21, and 28 - Reference substance (positive control):
- no
- Duration:
- 28 d
- Dose descriptor:
- NOEC
- Effect conc.:
- >= 52.3 µg/L
- Nominal / measured:
- meas. (arithm. mean)
- Conc. based on:
- act. ingr.
- Basis for effect:
- other: Mortality, wet weight, body length, pseudo-specific growth rate
- Details on results:
- No abnormal condition or behaviour was observed at any test concentration up to and including 52.3 µg/L (highest concentration tested, mean measured value).
During the test no test item related mortality occurred. One fish was lost due to handling. At any concentration up to and including 52.3 µg a.s./L (measured), neither any significant effect nor any trend was observed.
The fish weights increased by approx. 100 % every 14 d, thus the quality criterion for the controls (at least 50% in 28 d) was met even by all treatments.
Regarding the pseudo-specific growth rate, no test item related effect was observed. The NOEC was established at ≥ 52.3 µg a.s./L (measured).
Summary of the effect data is given in Table A7.4.3.2- 9 - Reported statistics and error estimates:
- Since no effect on mortality, weight and pseudo-specific growth rate occurred, no statistical evaluation was performed.
- Validity criteria fulfilled:
- yes
- Conclusions:
- The NOEC of Amines, N-C10-C16-alkyltrimethylenedi-, reaction products with chloroacetic acid in juvenile rainbow trout (Oncorhynchus mykiss) was determined to be ≥ 52.3 μg a.i./L; no effects were observed up to and including the highest tested concentration.
- Executive summary:
The effect of Amines, N-C10-C16-alkyltrimethylenedi-, reaction products with chloroacetic acid (20% a.i., as manufactured) on growth and survival of juvenile rainbow trout (Oncorhynchus mykiss) was tested according to OECD guideline 215 (2000) at nominal concentrations of 4.7, 9.4, 18.8, 37.5 and 75.0 μg active substance/L under flow-through conditions for 28 days.
At mean measured concentrations up to and including 52.3μg a.s./L, neither any significant effect nor any trend was observed. The fish grew well (203–223% of start weight) during the test and fulfilled the control validity criteria of the OECD Guideline 215 at all treatment levels. As no effect was observed, the NOEC of the test item related to mean measured concentration was determined to be ≥ 52.3 μg a.s./L, representing ≥ 261.5 μg test item per litre.
