Bioaccumulation: aquatic / sediment

In a valid guideline test (OECD 305) [CITI Japan 1982], using flow-through conditions for up to 8 weeks, the bioconcentration factors in carp ranged from 490 - 2750 L/kg tissue wet weight for individual fish (at an average exposure concentration of 50 µg/L). The lower exposure concentration of 5 µg/L resulted in lower values ranging from 220 - 980 L/kg. The mean BCF under steady-state conditions (time 4 to 8 wks) reached 870 and 640 at 50 and 5 µg/L, respectively. A post-exposure elimination phase had been included: Tentative DT50 depuration times can be estimated to be about 1.5 to 2 d. The test substance was categorised as "moderately bioaccumulating" by the investigators.
