| Abstract |
A flow-through test system for the study of toxicity and bioaccumulation processes is described. The apparatus can operate within a very wide range of flow rates. Flow deviations are less than 2% and the variation in test-agent concentration, (determined for copper) ranges from 3 to 8%. As a practical test a copper-toxicity experiment on adult Artemia was carried out and the results compared with data obtained from a similar but static assay. The results indicate that: - bioassay and accumulation experiments must preferably be carried out under flow-through conditions to keep the concentration and bioavailability of the toxicant as constant as possible;- the data analysis must be based upon measured test-solution toxicant-concentrations rather than on expected values. |
