- Executive summary:
The aquatic bioaccumulation of the test substance was determined in accordance with the OECD Guideline for Testing of Chemicals 305. The aquatic bioaccumulation was measured in a flow-through fish test, using carp, to assess the bioconcentration in fish. The fish was exposed to the test substance at concentrations of 3.84 µg/L and 38.5 µg/L in flow-through test conditions at 24.1°C-25.0°C for 28 days. The BCF was found to be < 41.7 at 3.84 µg/L and < 4.2 at 38.5 µg/L.
