Additional information

The effects of the test substance on algae was investigated in a GLP-study according to OECD guideline 201. The test was performed under static conditions using Pseudokirchneriella subcapitata as test species and included an analytical monitoring. Based on growth rate an EC50 (72 h) of 0.21 mg/L (measured concentration) was reported. Additionally, an NOEC (72 h) of 0.11 mg/L (measured concentration) was determined [NOTOX BV 2009b].
