Additional information

The substance was not acutely toxic to fish when tested according to OECD 203. The calculated 96-h EC50 is 19.8 mg/L; calculated from the geometric average concentrations of the EC0 (14.3 mg/L) and the EC100 (25.4 mg/L) assuming 37% loss over the course of the 96-hour fish assay at 22ºC.

 

The substance was not acutely toxic to Daphnia magna when tested according to OECD 202. The calculated 24-h EC50 is 75 mg/L (nominal) with 95% CL of 65-90 mg/L.

 

The substance was reported to have low toxicity to the green algae Pseudokirchnerella subcapitata, with a 72-h EL50 value for growth rate of greater than 160 mg/L (nominal), and for biomass of 110 mg/L (nominal) in an OECD guideline study (Test No. 201).

 

The substance was reported to have low toxicity to microorganisms derived from activated sludge, with a 3-h IC50 value for growth inhibition of greater than 100 mg/L (nominal) in an OECD guideline study (Test No. 209).
