Comparative studies on additive effects of sodium dodecylbenzensulfonate and sodium stearate on uptake of chemicals by willow shiner (Gnathopogon caerulescens).

Comparative studies between sodium dodecylbenzensulfonate (DBS) and sodium stearate (SNa) were performed on the additive effects of the uptake of chemicals in a fresh water fish, the willow shiner (Gnathopogon caerulescens), by the use of a continuous flow water system. The chemicals selected were 2,4,6-trichlorophenyl-4'-nitrophenyl ether (CNP) as a non-polar lipophilic substance and cadmium salt (Cd) as polar hydrophilic substance. DBS had no promotive and depressive effects on the uptake of Cd. SNa had no promotive and depressed effects on the uptake of CNP and Cd.
