Description of key information

Algae: ErC50(72h) = 31.19 mg/L, NOEC = 3.28 mg/L (reference 6.1.5 -1)

Daphnia: EC50(48h) > 100 mg/L (reference 6.1.3 -1)

Additional information

The toxicity of the test item to the unicellular freshwater green alga Pseudokirchneriella subcapitata was determined according to the principles of OECD 201 and Council Regulation (EC) No. 761/2009 C.3 (reference 6.1.5 -1). The EC50-values for inhibition of growth rate (ErC50) and yield (EyC50) after 72 hours were 31.19 mg/L and 8.93 mg/L, respectively. The NOEC-values for inhibition of growth rate and yield after 72 hours were 3.28 mg/L and 2.34 mg/L, respectively.

The acute immobilisation of the test item to daphnia magna was determined according to OECD guideline 202. The EC50 value after 48 h was determined to be > 100 mg/L (reference 6.1.3 -1).
