Additional information

Acute toxicity to fish was investigated in a reliable key study according to OECD 203 and in compliance with GLP (RCC, 2000, RL1). As the test item was highly insoluble in water, a limit test was performed with a supersaturated solution prepared at 100 mg/L test item and filtered through 1.2 µm glass wool filter. Test concentrations were analytically verified. During exposure, no adverse effect (mortality) or other symptoms of intoxication (sublethal efffects) was observed. In conclusion, the test item showed no sign of acute toxicity to zebrafish above the maximum water solubility of the test item. Derived effect concentrations were: 96h-LC50 (zebrafish) > 0.03 mg/L (measured), 96h-LC50 (zebrafish) > 100 mg/L (nominal; supersaturated solution), 96h-LC0 (zebrafish) >= 0.03 mg/L (measured), 96h-LC0 (zebrafish) >= 100 mg/L (nominal; supersaturated solution).
