Test conditions

Details on test conditions:
Five Gold orfes were raised in a test vessel with 8L of water, in which the 14-C-labeled chemical was dissolved at a concentration of 50ppb. The fish were not fed during the 3-day test. The vessel was closed and the water surface was stirred with a blade stirrer gently to provide air exchange and movement of water.
Details on estimation of bioconcentration:
At the end of the experiment, the concentration of AMP was determined by measuring the radioactivity of the fish and in the water and, from that, the accumulation factor was determined.
