Lipid analysis:
The lipid content of the fish was determined at the start and at the end of the study, from 2 fish per test concentration and 1 fish from the control group, respectively. Since recoveries of the test item in fish on day 28 indicated that a depuration phase could be waived no depuration phase was carried out. The samples for lipid analysis in fish were taken at day 28 (test end). The lipid content was determined gravimetrically by extraction with n-hexane. The lipid content of the food was provided by the manufacturer: 15 % (raw fat).

Study Design
A minimised bioaccumulation study with rainbow trout (Oncorhynchus mykiss) was conducted to determine the bioconcentration potential of the test material. An exposure (uptake phase) of 28 days was carried out. The depuration phase was waived, since the measured concentration in fish was < 50 µg test material / g fish. A flow-through test with 2 groups (one control group and one exposure group) was carried out. The concentration of the test item was determined via LC-MS/MS analysis. Four fish were sampled on uptake phase days 14 and 28 from the exposure group. Two fish were sampled from the control group on uptake phase day 28. Samples of the aqueous phase were taken and analysed on uptake phase days -2, -1, 0, 2, 7, 14, 16, 19, 20, 22, 23 and 28 from the exposure group and on uptake phase day 0 and 28 from the control group. The lipid content of the fish was determined at the start and end of the study from 2 fish for the exposure group and one of the control group.
The definitive study was conducted at DR.U.NOACK-LABORATORIEN, Sarstedt, Germany from June 13 to July 20, 2012 with the definitive exposure phase from June 13 to July 11, 2012, according to OECD Guideline 305 (Draft 2011).
Results
No significant uptake of the test item in fish was observed. Therefore, no uptake I depuration rates and no bioconcentration factors (steady state and kinetic, respectively) have been calculated. The bioconcentration factors at any sampling date during the uptake phase have been calculated based on fish body weight.
Uptake phase:
The aqueous concentrations at the beginning (uptake days 0 and 2) were in the range of 65 to 75 % of the nominal values. Thereafter, they were stable in the range of 92 - 118 % of the nominal values throughout the uptake phase. There was no increase of the test item concentrations observed in the fish. All the measured concentrations in fish were below 50 µg test item / g fish.
No depuration rates were calculated since no significant uptake was observed. The depuration phase was waived.
The bioconcentration factors (any time and lipid normalised, calculated on day 28) determined in this study with the test item were 12 and 10, respectively.
The validity criteria regarding temperature, oxygen saturation and mortality were fulfilled. The mean measured aqueous concentration (days 0 to 28) was 0.2 mg/L. On the first two sampling days the measured concentrations were below 20 % of the mean measured concentration (65 to 75 % of the mean measured concentration). From uptake day 7 to uptake 28 the measured values were in the range of 92 to 118 % of the mean measured concentration. Only negligible amounts of the test item were found in any analysed fish. These values have no impact on the validity of the study.
Conclusion
Under the conditions of this assay, there was no significant bioaccumulation observed. The result is below the regulatory value of concern regarding bioaccumulation.
