Effects of environmental and physiological variables on the uptake of hydrophobic contaminants by the gills of rainbow trout, Salmo gairdneri (Richardson)
The uptake of contaminants by diffusion across fish gills may be altered by changes in the contaminant's physicochemical form or changes in fish respiration. This study investigated the effects of changes in contaminant uptake due to sorption to humic acid and changes in fish respiration, induced by altering respiratory demand via an acute change in temperature and by altering the diffusional capacity of the gill membrane by exposure to chlorine. In each experimental design the uptake of selected polycyclic aromatic hydrocarbons and polychlorinated biphenyl congeners by the gills of rainbow trout, were measured simultaneously with measurements of fish respiratory functions using a fish metabolic chamber. 110 refs., 19 figs., 7 tabs.
