Description of key information

ErC50 (72h) = 115.82 mg/L (OECD 201, Pseudokirchneriella subcapitata)
NOErC (72h) = 3.8 mg/L

Key value for chemical safety assessment

Additional information

One study is available on the toxicity of the test substance to algae. The study was conducted according to OECD guideline 201 and GLP in a static system, using Pseudokirchnerella subcapitata as test organism (Goßmann, 2011). The algal culture was exposed to nominal test concentrations of 100, 32, 10, 3.2 and 1.0 mg/L, during 72 hours. The NOErC and ErC50 values were determined to be 3.8 mg/L and 115.82 mg/L, respectively, based on growth rate.
