For the determination of the stability of the test item under the test conditions and of the maintenance of the test item concentrations during the test period, duplicate samples from the test media of all test concentrations and the control were collected at the end of the test (after 48 hours) by pouring together the contents of the test beakers of each treatment.

The test medium of the highest test concentration of nominal 10 mg test item/L was prepared by dissolving 10.2 mg test item into 1020 mL test water by intense stirring for 15 minutes. Adequate volumes of this test medium were diluted with test water to prepare the test media of the other desired test concentrations.

- Details on results:
- After 48 hours of exposure no immobilisation of the test animals was observed in the control and up to the test item concentration of 2.10 mg test item/L. At the concentration of 4.5 mg test item/L 10 daphnids were immobile. At the highest test item concentrations of 10.0 mg test item/L 20 daphnids were immobile, respectively.
- Results with reference substance (positive control):
- In the most recent test with the reference item potassium dichromate the EC50 after 24 hours was determined to be 1.58 mg test item/L, indicating that the sensitivity of the Daphnia was consistent with the level proposed by the OECD 202 guideline (EC50-24 h between 0.6 and 2.1 mg potassium dichromate/L).
- Reported statistics and error estimates:
- The 24-hour and 48-hour EC50, EC20 and EC10 and the 95 % confidence limits were calculated by Probit analysis.
The NOEC and LOEC after 24 and 48 hours were calculated by Step-down Cochran Armitage test procedure.
The software used to perform the statistical analysis was ToxRat Professional, Version 3.2.1, ToxRat Solutions GmbH.

Title:
Fluormorpholinylacrylaldehyd (FMA): Acute Toxicity to Daphnia magna in a Static 48-hour Immobilisation Test
Purpose:
The purpose of this study was to determine the influence of the test item Fluormorpholinylacrylaldehyd (FMA) on the mobility of Daphnia magna.
For this purpose, young daphnids (< 24 hours old) were exposed in a static test to various concentrations under defined conditions for 48 hours. The recorded effects were the mobility of the daphnids after 24 and 48 hours. The test method of application and the test system are recommended by the test guidelines and Daphnia magna is the recommended test species. The purpose of the analytical part of this study was to verify the concentrations of the test item in the test medium.
Guidelines:
-OECD Guideline for Testing of Chemicals No. 202: "Daphnia sp., Acute Immobilisation Test" adopted April 13, 2004
-SANCO/3029/99 rev.4 11/07/00: Residues: Guidance for generating and reporting methods of analysis in support of pre-registration data requirements for Annex II (part A; Section 4) and Annex III (part A; Section 5) of directive 91/414

Results
Biological test results:
After 48 hours of exposure no immobilisation of the test animals was observed in the control and up to the test item concentration of 2.10 mg test item/L. At the concentration of 4.5 mg test item/L 10 daphnids were immobile. At the highest test item concentrations of 10.0 mg test item/L 20 daphnids were immobile, respectively.
Analytical test results:
The quantification of the test item Fluormorpholinylacrylaldehyd (FMA) in the test samples was performed using liquid chromatography with UV detection.
At the start of the test and after 48 hours test duration 102 % of the nominal test concentrations were found (average of all test concentrations).
Conclusion:
The toxic effect of the test item Fluormorpholinylacrylaldehyd (FMA) to Daphnia magna was assessed in a static concentration-response test. The 48-hour NOEC was determined to be 2.1 mg test item/L. The 48-hour LOEC was determined to be 4.5 mg test item/L and the 48-hour EC50 value was determined to be 4.5 mg test item/L.
The initial concentrations and the maintenance of the exposure concentrations during the test were verified in the analytical part. All reported results refer to nominal values since the concentrations of the test item were within ± 20% of the nominal concentrations during the test. This study is classified as acceptable and satisfies the guideline requirements for an acute toxicity study with freshwater invertebrates.
