The following concentrations of 2-(2-Vinyloxyethoxy) ethyl acrylate were tested: nominal 25, 50 and 100 mg/L. Additionally, a biological control was tested in parallel (test water without test item).
- Sampling method:
For the determination of the actual test item concentrations, the following samples were taken:
Just before the start of the test:
- duplicate samples from each test medium (without daphnids)
- duplicate samples from the control (without daphnids)
After 24 and 48 hours:
(stability samples) - duplicate samples from each test medium
- duplicate samples from the control:
For the 24-hour and 48-hour stability samples additional flasks with adequate volumes of the freshly prepared test media of all test concentrations and the control were incubated during the test period under the same conditions as in the actual test (but without daphnids).
- Sample storage conditions before analysis:
tested immediately after sampling- Vehicle:
- no
- Details on test solutions:
- PREPARATION AND APPLICATION OF TEST SOLUTION (especially for difficult test substances)
The test medium of the highest nominal concentration of 100 mg/L was prepared by dissolving 60.9 mg of test item completely in 600 mL of test water using ultrasonic treatment for 10 minutes and intense stirring for 10 minutes at room temperature. Adequate volumes of this test medium were diluted with test water to prepare the test media with the lower test item concentrations. The test media were prepared just before introduction of the daphnids (i.e., start of the test).
- Eluate:
Not applicable
- Controls:
For evaluation of the quality of the daphnia clone and the experimental conditions, potassium dichromate is tested as a positive control at least once a year. The latest result of the positive control test in September 2005 (48-hour EC50: 0.81 mg/L, RCC Study No. A28102) showed that the toxic performance was valid and within the historical range of the RCC laboratory (from 1996 to 2005: 48-hour EC50: 0.53-1.1 mg/L).

The biological results are listed in Table 1.
During the first 24 hours of the test no immobility of the test organisms was observed in the control and up to and including the test item concentration of 50 mg/L. At the highest test concentration of 100 mg/L, 55% of the test organisms were found to be immobile.
The 24-hour EC50 of the test item was calculated to be 96 mg/L (95% confidence limits not calculable). The 24-hour EC0 was 50 mg/L, the 24-hour EC100 was > 100 mg/L.
After 48 hours of exposure no immobility of the test organisms was observed in the control and up to and including the test item concentration of 25 mg/L. At the concentration of 50 mg/L, 35% of the daphnids were found to be immobile. At the highest test concentration of 100 mg/L all test organisms were immobile after the exposure period of 48 hours. The 48-hour EC50 was calculated to be 55 mg/L with 95% confidence limits from 40 to 77 mg/L.
The 48-hour EC0 and the 48-hour NOEC (highest concentration tested without toxic effects after 48 hours) of 2-(2-Vinyloxyethoxy) ethyl acrylate were both 25 mg/L, since no immobilization was observed in the test organisms exposed to the test item at levels of up to and including this test concentration. The 48-hour EC100 was 100 mg/L.
No remarkable observations were made concerning the appearance of the test media. All test media were clear solutions throughout the entire test duration. - Results with reference substance (positive control):
- - Results with reference substance valid?
Yes
- Mortality:
No mortalities recorded.
- EC50/LC50:
After 48 hours of exposure no immobility of the test organisms was observed in the control. - Reported statistics and error estimates:
- None stated in report
- Validity criteria fulfilled:
- yes
- Conclusions:
- After 48 hours of exposure no immobility of the test organisms was observed in the control and up to and including the test item concentration of 25 mg/L. At the concentration of 50 mg/L, 35% of the daphnids were found to be immobile. At the highest test concentration of 100 mg/L all test organisms were immobile after the exposure period of 48 hours. The test gave an EC50 value of 55mg/l and an NOEC value of 25 mg/l
- Executive summary:
The acute toxicity of the test item 2-(2-Vinyloxyethoxy) ethyl acrylate to Daphnia magna was determined in a 48-hour static test according to the EU Commission Directive 92/69/EEC, Part C.2 (1992), and the OECD Guideline for Testing of Chemicals, No. 202 (2004). The nominal test item concentrations tested were 6.3, 12.5, 25, 50 and 100 mg/L. Additionally, a control was tested in parallel. The analytically determined concentrations of the test item in the analyzed test media from the sampling times at the start, after 24 hours and at the end of the test were between 93 and 101% of the nominal values. Thus, the test item 2-(2-Vinyloxyethoxy) ethyl acrylate was stable during the test period of 48 hours under the conditions of the test, and the reported biological results are based on the nominal concentrations of the test item.
The biological test results:
− 24-hour EC50: 96 mg/L (95% confidence limits not calculable)
− 24-hour EC0: 50 mg/L
− 24-hour EC100: > 100 mg/L
− 48-hour EC50: 55 mg/L (95% confidence limits: 40 - 77 mg/L)
− 48-hour EC0 and
48-hour NOEC: 25 mg/L
− 48-hour EC100: 100 mg/L
