Hepatic mixed-function oxidases in California flatfishes are increased in contaminated environments and by oil and PCB ingestion

Hepatic mixed-function oxidases (MFOs) were measured in the bothid flatfishes Citharicthys sordidus and Citharicthys stigmaeus from relatively uncontaminated and from polluted coastal populations of California, USA, at various times of the year during 1979-1980 and individuals fed crude oil and poly...

Description
Summary:Hepatic mixed-function oxidases (MFOs) were measured in the bothid flatfishes Citharicthys sordidus and Citharicthys stigmaeus from relatively uncontaminated and from polluted coastal populations of California, USA, at various times of the year during 1979-1980 and individuals fed crude oil and polychlorinated biphenyl-augmented food in the laboratory. For C. sordidus , aryl hydrocarbon hydroxylase (AHH)-specific activity was generally highest around the Los Angeles County sewage outfall, and lowest in relatively unpolluted Monterey Bay. For C. stigmaeus , which had about 10 times less specific activity than the foregoing species, specimens from the Santa Barbara petroleum seep had significantly greater AHH-specific activity than those from Monterey Bay.
