Additional information

The short-term toxicity test to fish (Scheerbaum_2006) performed according to OECD 203 and GLP was rated with RL=1 (reliable without restrictions) and used as a key study. The results indicate that SymHelios® 1031 was toxic to Zebrafish after 96 hours at a concentration > 0.243 mg/L (geometric mean measured concentration) and greater. The LC50(96 hours) was 0.829 (95% CL: 0.718-0.956 mg/L) mg/L. The NOEC after 96 hours was 0.243 mg/L (geometric mean measured concentration).
