Abstract | The bioavailability of PCDD/PCDFs from municipal incinerator fly ash and sediment to freshwater fish has been studied. A preference to selectively bioaccumulate PCDD/PCDF isomers substituted in the 2,3,7, and 8 positions was observed. The depuration half life of 2,3,7,8-TCDD from carp was found to be 300-325 days. The rate of depuration of PCDD/PCDFs decreased with increasing degree of chlorination. |
