Toxicity of 3 water samples tested with the Acute fresh crustacean test using Daphnia magna : Test report

A risk assessment concerning the potential environmental risk of highway run-off water is performed by WMR, under the assignment of TNO. To support the risk assessment, the potential toxicity of three samples from run-off and surface water from different highways in Europe, is tested by WMR. Fresh water WET-tests are performed for species from multiple tropic levels, namely bacteria (Vibrio fischeri), algae (Raphidocelis subcapitata) and crustacean (Daphnia magna). This report describes the results of the acute immobilization tests with the freshwater crustacean Daphnia magna
