To study the relationship between the exposure concentration of surfactants and their concentration factors in fish bodies, carp Cyprinus carpio were exposed to several concentrations of three surfactans: ³⁵S-labelled sodium dodecyl sulfate (³⁵S-C12-AS), ¹²-AS), ¹⁴C-labelled sodium dodecylbenzenesulfonate (¹⁴D-n-C12-LAS) and ¹⁴C-labelled dodecy1 octa(oxyethylene) ether (¹⁴C-C12-AE(8)).<br> For the ³⁵S-C12-AS, the concentration of the ³⁵S-radioactivity in the fish increased gradually with exposure time in each solution. But after 72h of exposure it showed no remarkable changes. Its concentration factors after the equilibrium were 3.9-5.3, and these were not affected by the concentration of each solution. On the other hand, although the concentrations in fish of the ¹⁴C-radioactivity derived from the ¹⁴C-n-C12-LAS and ¹⁴C-C12-AE (8) reached their equilibrium after 72h of exposure, their concentration factors differed according to the concentration of the surfactant in each solution. They ranged from 16 at 9.1 μg/l to 400 at 300μg/l for ¹⁴C-n-C12-LAS, and from 39 at 9.9 μg/l to 220 at 1000μg/l for ¹⁴C-C12-AE (8). At even higher concentration in ¹⁴C-n-C12-LAS solution, however, the concentration factor was apt to be less.
