Endpoint summary

Additional information

In a bioaccumulation study according to OECD TG 305 bioconcentration factors (BCF) for the test substance were determined in Japanese Carp incubated in a continuous flow through system. 14C-labelled test substance was dissolved with the use of dispersant with 60 days of exposure and 14 days of elimination. Of the two concentrations tested, 0.05 mg/L was higher than the water solubility (< 0.04 mg/L), whereas 0.005 mg/L is considered to represent a water soluble concentration. It did not appear that the steady-state was achieved at either concentration level. On a weekly basis test water was analysed during the exposure period and test fish on days 7,13,28,42 and 60 of the exposure period and on day 1, 3, 7 and 14 of the elimination period. There was no dead fish. The appearance of Cyprinus carpio was normal by aquarium-side observations. BCF were calculated as the ratio of the concentration of the test substance between fish and the exposure water. The BCF was ≤ 46 for the high concentration level and ≤ 98 for the low concentration level. From the uptake and depuration rate constants, BCF were calculated as 26 for the high and 19 for the low concentration level. It is concluded that the test substance is not bioaccumulating in fish.
