Key value for chemical safety assessment

EC50 for marine water algae:
347.1 mg/L
EC10 or NOEC for freshwater algae:
3.13 mg/L
EC10 or NOEC for marine water algae:
118.4 mg/L

Additional information

Based on the availability of three guideline studies performed according to OECD 201, it can be concluded that the 72-h ErC50for growth inhibitory effects to algae is > 100 mg a.i./L (BASF AG 96/0054/60/1, BASF SE 371598, BASF AG 2/0002/88).

The NOEC for the green algae Desmodesmus s. in one study (BASF AG 96/0054/60/1) was 3.13 mg a.i./L. The same study also showed an EC10> 100 mg a.i./L. For the marine species, a NOEC of 118.4 mg a.i./L was observed (BASF SE 371598).
