Its relation with contaminant body burden (PAHs, PCBs, DDTs, and lindane) as well as environmental parameters (water temperature, salinity, oxygen concentrations, and suspended matter) was determined. As a general trend, low MFO and antioxidant enzyme activities were detected in February-March, a peak in late April, and a gradual decrease with a minimum in June. This pattern was similar to tissue concentrations of PAHs, PCBs, DDTs, and lindane normalized to lipid weight. Cytochrome P450 content, however, exhibited a steady decrease from February to June. The observed seasonal variations are presumably related to the metabolic status of the animal, itself dependent on such factors as gonadal ripening, food availability, and the hydrological cycle, which regulates productivity in the area Peer reviewed 2023-11-21T07:29:19Z 2023-11-21T07:29:19Z 1995-01 artículo Environmental Toxicology and Chemistry 14(1): 157-164 (1995) 0730-7268 http://hdl.handle.net/10261/339285 10.1002/etc.5620140118 1552-8618 en https://doi.org/10.1002/etc.5620140118 Sí none Society of Environmental Toxicology and Chemistry |
