Acute toxic to algae: ErC50 (72 h) = 5.67 mg/L
Algal toxicity was found in the same order of magnitude with EC50s
(72 h) of 3.93 mg/L and 5.67 mg/L for biomass production and growth
rate, respectively (geometric mean of the results of 2 tests;
Eisentraeger et al., 2003). For long-term toxicity to algae see above
(acute toxicity) the 72h-value can be regarded as multi-generation value
according to the TGD. However, a NOEC value is not given in the study.
Further algal studies are reported. With respect to test durations
and endpoints these are rated as not suitable for risk assessment.
