Content: 46.2 % (4 main constituents)
Test substance storage: At room temperature in the dark
Stability under storage conditions: Stable
Expiry date: 01 April 2016
Stability in water: Stability for at least 6 hours at room temperature

- yes
- Details on sampling:
- Singular samples for possible analysis were taken from all test concentrations and the control according to the schedule below.
Frequency: at t=0 h and t=48 h
Volume: 3 ml from the approximate centre of the test vessels
Storage: Samples were stored in a freezer until analysis.
At the end of the exposure period, the replicates were pooled at each concentration before sampling. Additionally, reserve samples of 3 mL were taken for possible analysis. If not used, these samples were stored in a freezer for a maximum of three months after delivery of the draft report, pending on the decision of the sponsor for additional analysis. - Vehicle:
- no
- Details on test solutions:
- The batch of FAT 40854/A TE tested was a reddish-brown powder consisting of 4 main constituents (46.2%) and the substance was completely soluble in test medium at the concentrations tested.
Preparation of test solutions started with the highest concentration of 100 mg/l. No special treatment other than careful mixing was necessary to completely dissolve the test substance in test medium. The lower test concentrations were prepared by subsequent dilutions of the highest concentration in test medium. The final test solutions ranged from clear and very slightly orange at 0.10 mg/l to clear red at 100 mg/l. - Test organisms (species):
- Daphnia magna
- Details on test organisms:
- TEST ORGANISM

- Executive summary:
In a GLP-compliant acute toxicity study in Daphnia magna with FAT 40854/A conducted according to OECD guideline No. 202 and EU method C. A combined limit/range-finding test was performed. Twenty daphnia per test group (4 replicates, 5 per vessel) were exposed to a control and a nominal concentration of 100 mg/l in the limit test. In the combined range-finding test ten daphnia per test group (2 replicates, 5 per vessel) were exposed to nominal concentrations of 0.10, 1.0 and 10 mg/l. The total test period was 48 hours. Samples for analytical confirmation of actual exposure concentrations were taken at the start and the end of the test period. Analyses of the samples taken from nominal 100 mg/l showed measured concentrations of 112 mg/l at the start and 116 mg/l after 48 hours of exposure. Test results were based on the nominal concentration as the measured concentrations deviated less than 20 % from nominal. The study met the acceptability criteria prescribed by the protocol and was considered valid. FAT 40854/A did not induce acute immobilization of Daphnia magna at 100 mg/l after 48 hours of exposure (NOEC). The 48h-EC50 exceeded an analytically confirmed concentration of 100 mg/l.
