Description of key information

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
100 mg/L

Additional information

No observed effect concentration after 21 days > saturation concentration.

Saturation concentration:

2000 mg of the test article was stirred during 48 h with 2000 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 concetration

noeffects are observed.There is no observed toxic effect at 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.
