Ethoxyresorufin-O-deethylase induction in fish from a watershed exposed to a non-point source pollution of agricultural origin


Water Research Oxford 27(3): 449-455
Ethoxyresorufin-O-deethylase induction in fish from a watershed exposed to a non-point source pollution of agricultural origin
The activity of a P-450-dependent enzyme, ethoxyresorufin-O-deethylase (EROD), was measured in liver of fish from a watershed exposed to pesticide runoff from nearby vineyards. A correlation was observed between pesticide runoff and enzyme activity. This is the first field trial on the use of the cytochrome P-450 system as a biochemical indicator for assessing potential exposure to trace levels of complex mixtures of pesticides in the aquatic environment. The results might be useful for agencies designing monitoring assessment programs for ecotoxicological risk.
