- Executive summary:
The acute toxicity of FAT 40406/A to Daphnia magna was determined in a 48-h static test according to the OECD Guideline for Testing of Chemicals, Section 2, No. 202, adopted April 04, 1984 and the EEC Directive 84/449, L 251, Part C 2. The test was performed in compliance with the GLP. The nominal concentrations tested were 62.6, 125, 250, 500 and 1000 mg test substance/L and a control without any additions. The 24-h EC50 of the test substance was calculated to be 840.9 mg test substance/l with 95 % confidence limits from 723.7 to 977.0 mg test substance/l. The 24-h EC0 (= NOEC, No Observed Effect Concentration after 24 h) was 250 mg test substance/L. The immobility of one Daphnia in the nominal concentration of 62.6 mg/L was obviously not caused by a toxic effect of the test substance, since in the next higher concentration no immobility was observed.
The 24-hour EC100 was higher than 1000 mg test substance/L. After 48 hours exposure, 5 % immobility was observed at a concentration of 62.6 mg/L (1/20 daphnids), 10 % immobility was observed at 250 mg/L (2/20 Daphnia) and 65 % immobility was observed at 500 mg/L (13/20 daphnids). 100 % immobility was observed at 1000 mg/L (20/20 daphnids) No immobility was seen at any of the other concentrations. After 48 hours test duration the toxicity of the test substance has increased. The 48-h EC50 was calculated to be 420.5 mg test substance/l with 95 % confidence limits from 333.5 to 530.1 mg test substance/L. The 48 -h EC0 (NOEC after 48 h) was 125 mg test substance/L, the 48h EC100 amounted to 1000 mg test substance/L. In the control no immobility or mortality of the test animals was observed.
The test results:
- 24h EC50: 840.9 mg test substance/L (95 % Conf. limits: 723.7- 977.0 mg test substance/L)
- 24h EC0: 250.0 mg test substance/L
- 24h EC100: >1000 mg test substance/L
- 48h EC50: 420.5 mg test substance/L (95 % Conf. limits: 333.5 - 530.1 mg test substance/L)
- 48h EC0: 125.0 mg test substance/L
- 48h EC100: 1000 mg test substance/L
All reported results are related to nominal concentrations of the test substance. During test duration the test substance concentrations were in the range of 99.5 - 114.7 % of the nominal values, under test conditions the test substance was sufficiently stable.
