toxicity towards freshwater algae was determined in a study according to
OECD TG 201 and in compliance with GLP criteria (EAG, 2019). In this
study, exponentially growing freshwater alga (Pseudokirchneriella
subcapitata) were exposed to solutions of the test substance of 0,
1.3, 2.5, 5.0, 10 μg/L (nominal concentrations) for 72 hours under
static conditions. The test was performed in three replicates per test
concentration and six for the control groups. The initial concentrations
and the maintenance of the exposure concentrations during the test were
analytically determined. Cell density was measured after 24, 48 and 72
hours exposure and the growth rate, yield and biomass per time point
were determined. Throughout the test, no effects on the growth rate and
yield were observed. Based on these findings, the 72-h EC50 values for
growth rate and yield/biomass are determined to be >10 μg/L (highest
concentration). The NOEC was also determined to be equal to 10 μg/L.
