ADDITIONAL REPORTED EFFECT CONCENTRATIONS
- ErC20 (24h) 57.2 mg/L- ErC50 (24h) 116.8 mg/L - ErC90 (24h) -- ErC20 (48h) 64.5 mg/L- ErC50 (48h) 96.2 mg/L- ErC90 (48h) -
The 72 -h ErC50 is 84 mg/L in freshwater
algae (D. subspicatus).
The toxicity towards freshwater algae was
determined in a study according to DIN 38412 L9 (not GLP-compliant). In
this study, exponentially growing freshwater alga (Desmodesmus
subspicatus) were exposed to nominal test substance concentrations
of 7.812, 15.625, 32.25, 62.5, 125, 250 and 500 mg/L under static
conditions. At the start of the test and after 24, 48, 72 and 96 hours
exposure duration, the algae were scored for number of cells. Based on
these findings, the 72-h EC50 values for growth rate was determined at
83.7 mg/L. The EC20 and EC90 were determined at 51.4 and 147.3 mg/L,
