An acute, static 72-hour toxicity
test was conducted with the algae Pseudokirchnerella subcapitata at
nominal concentrations of 0, 300, 540, 960, 1700 and 3000 mg/L. The mean
measured concentrations used in LC50 calculations were 0, 1.50, 2.03,
4.24, 7.02 and 14.4 mg/L. Because of the volatile nature of the test
item, the test was performed in 500 mL Erlenmeyer flasks with stoppers.
Control and test solutions were conducted with six and three replicates,
respectively. In all the test groups, the temperature of the test
solutions were 22 ± 2°C, the pH values were 7.8 to 10.4 and the biomass
in the control cultures increased exponentially, fulfilling the test
Based on the mean measured
concentrations, the 72-hour ErC50 was 14.4 mg/L and the NOECr was 4.24
