Predictive value of laboratory tests with aquatic invertebrates: influence of experimental conditions 27
Persoone, G.; Van de Vel, A.; Van Steertegem, M.; De Nayer, B..
Considering the difficulty of making meaningful extrapolations of laboratory bioassay data to real world situations, short-term tests have been carried out in a factorial pattern to determine the magnitude of effect variation resulting from changes in experimental abiotic conditions.Three selected zooplankton species (the rotifer <i>Brachionus plicatilis</i>, the brine shrimp <i><i>Artemia</i> salina</i> and the waterflea <i>Daphnia magna</i>) have been exposed to increasing concentrations of two chemicals (one inorganic and one organic) in different combinations of two major environmental variables.For the brackish water rotifer <i>B. plicatilis</i> the acute toxicity of potassium dichromate and...

The influence of temperature and salinity on the sensitivity of <i>Artemia</i> nauplii to chemical compounds 27
Persoone, G.; Van Steertegem, M..
The toxicity of chemicals to aquatic organisms is mostly determined in a set of experimental conditions which are close to optimal for the test species. Because in nature organisms have to cope with fluctuating environmental conditions which can range during the course of the year from optimal to suboptimal, up to the limits of the tolerance range, the conditions under which routine bioassays are normally performed do, however, not reflect the large range of situations occurring in the field. Considering the scarcity of information on the effect of fluctuating environmental conditions on the sensitivity of test species to toxicants, a comparative laboratory study has been undertaken to determine the combined influence of environmental variables on the...
