- After acclimatisation period, the fish (Cyprinus carpio) were transferred into the test media under flow through conditions. Exposure concentrations were analytically verified at days 0, 5, 14, 21, and 28. The analytical values show that the nominal concentrations of 0.0025 and 0.000252 mg/L were maintained during the experimental phase.
At days 0, 5, 14, 21, 25 and 28 two fish each were removed from each test group. Body weight was determined. The fish were homogenised and extracted with acetonitrile and n-hexane and the extract was analysed.
Due to the low bioaccumulation potential, no depuration phase was required. - Duration:

- Executive summary:
Purpose
The purpose of this study was to determine the bioconcentration potential of the test material in fish under flow-through conditions. During the GLP compliant test the lethal and other effects in fish were determined during the exposure period of 28 days.
Study Design
The study was performed according to the OECD Guideline for Testing of Chemicals 305 (Bioconcentration: Flow-through Fish Test) adopted on June 14, 1996 using two test material concentrations for exposure to Cyprinus carpio. Two environmental concentrations of the test material of 0.0025 and 0.00025 mg/L were used in this study. HCO-40 was used as vehicle at concentrations of 1.0 mg/L. The exposure was maintained during the couse of the study at expected nominal values. The concentrations have been verified analytically using a HPLC method with UV detection.
Results
There were no mortality and no signs of toxicity detected throughout the study in any dose group up to 28 days of exposure.
Conclusion
The test material showed no relevant toxic potential at concentrations above the limit of water solubility.
