Concentration of test substance in test water:
The measured concentrations of the test substance in test water are
shown in Table-1. Each concentration of the test substance was
maintained at more than 91% of each nominated concentration. The
variation of the concentrations of the test substance was within ± 20%
of each other.
concentrations of the test substance in test water [mg/L]
BCFs are shown in Table-2. BCFs of the test substance were <
Calculation of BCFs in a steady-state (BCFss)
Because all of BCFs were less than 100, it was evaluated that a
steady-state was reached at 28th day. BCFss was calculated an the basis
of the results of analysis alter 14, 21 and 28 days from the initiation
(1) Concentrations oftest substance in test water in a steady-state
The average concentrations of the test substance in test water in a
steady-state are shown in Table-3. The average concentration was 93.6%
of the nominated concentration.

steady-state (Unit : mg/L)
(2) BCFs in a steady-state (BCFss) BCFss was calculated as <6.2.
In a test for bioconcentration according to OECD 305 and compliant to
GLP (reliability category 1) no potential for bioconcentration of the
submission substance in the fish Cyprinus carpio could be shown. As all
measured fish samples within the 28 days exposure period had
concentrations below the limit of determination, the maximal possilbe
BCFss is determined by the ratio of the limit of determination and the
mean measured concentrations in the test medium:
