The isomer-dependent bioavailability of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDDs and PCDFs) from municipal incinerator fly ash to freshwater fish was determined. It was observed that carp exposed to fly ash in a continuous-flow exposure readily accumulated select isomers of PCDDs and PCDFs. A preference for greater retention of isomers substituted in the 2, 3, 7 and 8 positions was observed. The Bioavailability Index (ratio of contaminant level in fish to level in fly ash) decreased with increasing degree of chlorination.
