Biological Effects Monitoring

Data from several previous experimental studies of hepatic mixed function oxidase (MFO) activity were reexamined to study the possible relationship between ethoxycoumarin O-de-ethylase activity and body weight and other factors in "uninduced" brook trout (Salvelinus fontinalis). Weight-specific O-de-ethylase activity was inversely related to body weight; regression of the log transformation of the total hepatic O-de-ethylase activity on log liver weight yielded a regression coefficient of 0.850 ± 0.047 close to the value of ~0.75 expected for a relationship based on overall metabolic rate. The regression coefficient was significantly higher in males than in females. Multiple regression analysis showed O-de-ethylase activity to be positively correlated with both microsomal protein and cytochrome P-450 content. The data confirm that size (or age) is a factor to be eliminated in any biological effects monitoring program based on MFO assays.Key words: mixed function oxidases, ethoxycoumarin O-de-ethylase, brook trout, Salvelinus fontinalis; hepatic mono-oxygenases

Biological Effects Monitoring

This paper describes the biological effects monitoring programme proposed by the North Sea Task Force (NSTF). The rationale for each of the recommended methods will be outlined and the advantages and limitations, within the framework of the objectives of the monitoring programme, will be discussed.
