Additional information

A GLP guideline study according to OECD 221 using Lemna gibba as a test organism was conducted (BASF SE 99E0861/11X565, 2012). This test was conducted instead of a study using algae because the test substance is a dyestuff which would influence the photosynthesis capacity of algae cells in the test solution. In this study, the ErC50 (7d) values on the frond number and the dry weight of the plants were determined to exceed the analytically verified test concentration of 320 mg/L.
