Description of key information
Studies were available for several of the streams in this Category. The reported 72 hour ErL50 range was 2.1-12.2 mg/L and the NOELR range was 0.18 to 8 mg/L.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 2.1 mg/L
- EC10 or NOEC for freshwater algae:
- 0.18 mg/L
Additional information
Data are available for the streams 64742-90-1, 68513-69-9, 85117-10-8, 69013-21-4 and 98072-36-7 from Brixham Environmental Laboratory (2004), Exxon (2003), BASF (2007), ExxonMobil (2003, 2004) and ECT Oekotoxikologie GmbH (2012). The ErL50 values reported ranged from 2.1 to 12.2 mg/L and the NOErLR ranged from 0.18 to 8 mg/L. These studies are considered reliable for assessment and so data will be read across to other members of the category.
