A system for conducting flow-through toxicity tests with larval fish
- Miami Univ., Oxford, OH (United States). Dept. of Zoology
Assessment of toxicological effects in aquatic systems commonly include larval fish 96-h LC50 determinations. The LC50 tests are conducted using static renewal as well as flow-through methods. However, in the case of chemicals with high vapor pressures or fugacity, static renewal methods may produce inconsistent results arising from the pulsed nature of exposure. In addition, in exposures involving these types of compounds, the fluctuation in concentration that can occur between renewals is unlike most exposure scenarios in nature. For these reasons, flow-through systems are often preferable. The authors report here on an inexpensive, easily constructed, flow-through system for toxicant exposure of small organisms. Data are presented to illustrate the capacity of the system to maintain uniform toxicant concentrations relative to static renewal methods.
