Additional information

Reliable short-term toxicity tests results are available for freshwater invertebrates (Daphnia magna) and algae (Pseudokirchneriella subcapitata) for the submission substance. The relevant short-term values are:


Daphnia: EC50 (48 h): 51 mg/L (nominal)

Algae: EC50 (72 h): 11 mg/L; EC10: 3.9 mg/L; NOEC: 1 mg/L (nominal)


Both studies used Total Organic Carbon (TOC) analysis to verify test concentrations. Since TOC analysis is a non-specific method, results are reported in terms of loading rates and expressed as mg test item per litre.
