Additional information

One reliable study is available for long-term toxicity to aquatic invertebrates of CHIMEXANE NV. The study is classified as reliable with restrictions (test substance concentration deviated from +/-20% of nominal, observations performed three times per week). The test was performed under semi-static conditions. Under the conditions of this study, the 21d-NOEC was determined to 0.036 mg/L and the 21d-LOEC was determined to 0.074 mg/L based on reproduction effects.
