- Metabolites:
- The test item converted and a converted with unknown structure product produced in the biodegradation study. Although, a part of the test item biodegraded, most of them remained. The LC-MS scan analysis was performed using test fish after 34 days of Level 1 and control fish after the experimental completion and the bioconcentration potential of the converted product was confirmed by comparison of these chromatograms. As a result, there was no remarkable peak originated from the converted product. Therefore, it is considered that bioconcentration potential of the converted product was low.

- Executive summary:
The objective of this study was to obtain laboratory data characterizing the bioconcentration potential of test substance in the common carp (Cyprinus carpio) through aqueous exposure. The nominal concentrations of 33.6 and 3.36 µg/L were selected and prepared. A control solution was also prepared in the same way but without any test Substance. Test fish were exposed to either the test solutions or the control solution for a total of 34 days. Observation of the test fish were made twice a day. Water temperature, flow rate, dissolved oxygen and pH was monitored in the study.
The test water of each level was analysed once before the first analysis of test fish and at the same time as analysis of test fish thereafter. Analysis of test fish was performed six times during the exposure period. Measured concentration of the Substance in water and the concentration in fish were taken after Day 1, 9, 15, 21, 28 and 34. Analysis of control fish was performed before the experimental start and after the experimental completion. Analysis of the test item in test water and test fish were performed with Liquid chromatography-tandem mass spectrometry (LC-MS/MS). The results were used to calculate the Bioconcentration factor (BCF) of the Substance.
The majority of the Substance could not be measured as the concentration values obtained were below the limit of quantification and/or were not subject to bioaccumulate because of the molecular weight is more than 800. The analysis recorded some values for minor parts of the UVCB Substance, which BCF values could be calculated for. Nominal concentration of 33.6 and 3.36 µg/L estimated an average BCF values range of 140-210 and 200-410, respectively, at steady-state. Overall it can be concluded that a BCF value is considered to be very low, therefore the potential for the Substance to bioaccumulation is also likely to be very low.

Description of key information
Initial attempts were made to experimentally determine the Bioconcentration Factor (BCF) in Fish for registration of the Substance. The Substance is considered to be a UVCB (Chemical Substances of Unknown or Variable Composition, Complex Reaction Products and Biological Materials). The majority of the Substance could not be measured as the concentration values obtained were below the limit of quantification and/or were not considered to be subject to bioaccumulate because of the molecular weight is more than 800. Consequently, QSAR was used to support the BCF study findings and ensure that the value is reflects the major component for that Substance..
The BCF value was estimated using QSAR models as follows:
Log BCF (EpiSuite) = 0.5 log(L/kg)
Bintein Model (QSAR ToolBox) = -6.7 log(L/kg)
CAESAR 2.1.14 = -0.02 log(L/kg)
Meylan 1.0.3 = 0.5 log(L/kg)
KNN/Read-Across 1.1.0 = 1.98 log(L/kg)
Based on the complex nature and physical properties of the substance made it difficult to provide a suitable BCF value. In the BCF study the substance was not expect to bioaccumulate based on it's molecular weight being more than 800. This is supported by the QSAR models conducted based on the structure which estimate that the Substance is likely to have extremely low BCF and proven by the estimated high Log Kow being > 6.5. The highest estimated BCF value has been used as a conservative key value for the chemical safety assessment.
Key value for chemical safety assessment
- BCF (aquatic species):
- 1.98 L/kg ww
