Abstract:In this experiment juvenil Siberia Sturgeon(weighing 10.18±0.3g) is exposed to waters with fluride apparent concentrations of 0, 4, 10, 62.5ppm, so as to study the additive effect on different tissues of the fish. Sampling was done after 30, 60 and 90 days of exposure. We choose 6 fish randomly out of each exposure concentration. The gill, liver, cartilage, bones, muscle, intestine and stomachs were taken and wash out the bloodstain on the outside of the fish, and these tissues were used to determine F concentration in them. ion selective eletrode was applied to determine F concentration. The result shows that F concentration in cartilage, bones and gills increase along with the exposure time and concentration(P<0.05), and the caculating effect and time effect is obvious. But the differentiation is not obvious when the concentration is heighten and the exposure time elongation.(P>0.05)
Key words: fluorion, Siberia Sturgeon, additive effect
