Additional information
A long-term daphnia test has been performed with diquat C16-18. The test is considered valid as all validity criteria have been fulfilled; Based on the test setup (GLP, Guideline study) and the extensive effort which has been paid to ascertain a realistic exposure of the test organisms and to quantify the extent of this exposure the results are considered to be reliable. Finally, the test result is considered adequate for the evaluation of the environmental risks in the EU applying the bulk approach considering the realistic worst case (low) concentrations of suspended matter and DOC in the river water used.
