The toxicity of the test substance to algae was tested in an OECD
Guideline 201 test. Algae were exposed to measured concentrations of
0.63, 1.74, 3.79, 7.64, and 12.7 mg/L for 72 hours. Negative controls
were also performed. Four replicates were performed. The NOEC was less
than 0.63 mg/L based on measured concentrations. The 72-hr EC50 based on
growth rate was 3.31 mg/L based on measured concentrations.
