OECD guideline 221.
In the preliminary test, nominal concentration were: 0, 10, 100 and 500 mg/l. Concentrations were determined by photometry at day 0 and day 7 and resulted to be stable. Therefore, static conditions were used for the test.
Definitive test was run as limit test, as no significant toxic effects were noted in the preliminary test. Effect levels were assessed based on nominal concentrations as measured concentrations were within the 80 - 120 % range of nominal ones.
