Additional information

BASF (1989) is a growth inhibition study on Scenedesmus subspicatus following DIN 38 412 method. The test was conducted under static test conditions and the test duration was 72 hours. Six concentrations were tested between 0.2 and 1.6 g/L. The GLP status of the study is not known and there was no analytical monitoring so effect values were based on nominal concentrations. The method and conditions are described adequately and the study is considered to be reliable and suitable for use for this endpoint.
