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.
