The use of the MFO (mixed-function-oxidase) system as an early effects measurement for the NBSP (National Benthic Surveillance Project) is being evaluated. Specifically, measurements are being made of hepatic aryl hydrocarbon hydroxylase (AHH) activity toward a common anthropogenic contaminant, benzo[a]pyrene (BaP). Several laboratory studies have been performed to determine both time- and dose-response curves for AHH activity in fish exposed to environmental contaminants, and measurements of hepatic AHH activity in fish collected during the fifth and sixth years (Cycles V and VI) of the NBSP have been begun. The authors present preliminary data from analyses of samples collected during Cycle V of the NBSP. Overall, the results have shown that measurement of hepatic AHH activity is a highly responsive indicator of contaminant exposure in benthic fish, making this measure an effective tool for use in environmental monitoring programs.
