EC number: 401-540-3
CAS number: 84632-65-5
In a 72-h acute toxicity study, the EC50 of sbustance is above saturation concentration.
Comments: EbC50 at 72 h: > saturation cone. ErC50 at 72 h: > saturation
conc. No observed effect conc. growth and biomass: > saturation conc.
Saturation concentration: 1000 mg of the test article was stirred during
48 h with 1000 ml water. The resulting suspension was filtered through a
micro-tissue filter (0.22 am). The water solubility of the substance is
smaller than 0.01 mg/l. At this value no effects are observed. There
is no observed toxic effect on the saturation solubility of the
substance in the test. The actual concentration in the test does not
increase when the nominal concentration increased due to the water
solubility of the substance is highly insoluble (less than 0.01mg/L).
According to the inquiry report , The water solubility of the substance
is smaller than 0.01mg/l. At this concentration no effects were
observed. Therefore, NOEC of the substance is above 100mg/L.
