Additional information

The earlier results from De Wolf (1991 & 1992) were discarded as experimentally less reliable than the later work (1993). To assess the bioaccumulation potential of the test item towards fish, Poecilia reticulata were exposed during seven days in a flow-through system at 23.5 ± 0.5°C, pH 7 -8, DO 7 mg/L to the substance (uptake). Afterwards the fish were transferred to clean water and observed over a depuration period of four days. No noticeable deviations from ordinary swimming or eating behaviour was observed either during exposure or elimination. The bioaccumulation was reported as BCF(whole body ww)=214 L/kg and BCF(lipid)=1620 L/kg. The whole body BCF is taken forward for classification purposes.
