Additional information

The long-term toxicity of the substance to Daphnia magna was tested in a study performed according to EG- guideline XI/681/86. In a semistatic test system the animals were exposed to the substance for 21 days and the reproduction was recorded. A NOEC (21 d) >= 100 mg/l was determined based on 70 % active ingredient in water. For 100 % active incredient a NOEC (21 d) >= 70 mg/l was calculated (BASF AG, 1999).
