Description of key information

Additional information

For the aquatic compartment two long term key studies are available. The algae test gave a ErC10 of 1.27 mg/L and the long term daphnia test a NOEC (reproduction) of 0.8 mg/L. For the effect assessment the EC10 for adult mortalilty of 0.712 mg/L will be used as a worst-case. Note that both long term key studies are higher tier studies performed in river water with relatively low (realistic worst-case) DOC and suspended matter concentrations. This means that for the risk assessment the bulk approach should be applied i.e. both the effect and exposure assessment are based on the total concentration (dissolved and sorbed).

For the toxicity to micro-organisms an EC50 of 289 mg/L was observed for activated sludge bacteria after 3 hour exposure.
