Description of key information

Most sensitive endpoint for the hazard assessment for the aquatic environment: EC50 of 0.0065 mg/L (for Chlorococcum sp.; algae).

Additional information

The environmental hazard assessment for (fresh-) water organisms and sediment habitats is supported by several acute studies (pelagic compartment) and by using scientific argumentation (sediment dwelling organisms).

For the environmental hazard assessment of the registered substance acute toxicity studies for freshwater and marine fish, acute data for daphnids and freshwater algae and cyanobacteria.

The short-term EC50/LC50 values for fish, Daphnia, algae were 16.3, > 106 and 0.0065 mg/L, respectively.

Algae is the most sensitive trophic level with an EC50 of 0.0065 mg/L. This value will be used as worst case scenario for the risk assessment of aquatic organisms.
