抄録

Rainbow trout Salmo gairdneri and carp Cyprinus carpio were exposed to 203HgCl2 at aconcentration of 0.5μg-Hg/l.<br> At relatively short-term(40h)exposure, the mean bioconcentration factor(BCF)of rainbowtrout was affected by pH of buffered exposure solution and was high at low pH as compared with that in high pH.<br> The BCF for the exposure of 17 days in the artificial water was about 800 for rainbow trout and carp, but the concentrations of 203Hg in fishes and those in the solution were not in equilibrium.The profile of bioconcentration in the river water was similar to that in the artificial water. The equilibrium BCF estimated using a simple linear differential equation were several thousands.
