A Toxicity Monitoring Technique Employing Populations of Daphnia Magna Held under Continuous Flow Conditions

A TECHNIQUE FOR MONITORING THE EFFECTS OF POLLUTANTS ON POPULATIONS OF DAPHNIA MAGNA (CRUSTACEA) IS DESCRIBED AND DISCUSSED. THE ANIMALS ARE HELD UNDER CONTINUOUS FLOW CONDITIONS. A SIMPLE AND RAPID SAMPLING METHOD PERMITS THE QUICK DETERMINATION OF POPULATION SIZE AND ANIMAL SIZE CLASS DISTRIBUTION. LONGTERM CHRONIC TOXICITY TESTS CAN BE RUN OVER SEVERAL GENERATIONS TO SHOW THE TOXIC IMPACT OF A POLLUTION ON POPULATION DYNAMICS. AS AN EXAMPLE THE INFLUENCE OF NICKEL OVER A PERIOD OF 21 DAYS IS REPORTED.
