Additional information
A non-GLP preliminary range finding test under static conditions over a period of 72 hours was conducted at the test facility. A saturated solution with a nominal loading of 100 mg test item/L was freshly prepared. Out of this saturated solution three concentration levels were prepared (by serial dilution) with the concentrations 0.100, 1.00 and 10.0% of the saturated solution.
Under the experimental conditions, no toxicity was observed for Pseudokirchneriella subcapitata.
