A OECD 201GLP study with Pseudokirchneriella subcapitata is available. An second OECD 201 study on Scenedesmus is available however, does not not provide sufficient information for the analysis of the results, thus was disregarded of the overall assessment. The report does not specify which growth endpoints were evaluated. Further detailed information on the results are missing thus do not allow a re-analysis of the results.
The study from 1988 did not report the stability of the test material and the endpoint assessed (growth rate/yield). Based on these obervation the study was repeated in 2012. The ErC50(72h) determined in the key study (2012) was 17.4 mg/L mean measured concentration and the NOEC was 7.11 mg/L.
