Abstract

(1) An in vivo whole fish preparation was evaluated for measuring the uptake efficiency of chemicals directly from the water across the gills of transected brook trout. (2) A continuous-flow system allowed a determination of the effects of environmental variables (i.e., dissolved oxygen) on the movement of chemicals across the blood-water interface at the gills. (3) Endrin uptake efficiency at two water concentrations (0.046 and 0.072 micrograms endrin/1) was 81 plus or minus 9% and 80 plus or minus 8%, respectively, indicating no significant effect of endrin concentration on uptake efficiency.
