Results of growth inhibition test that observe and investigate growth inhibition rate and abnormal behaviours, by exposing algae (Pseudokirchneriella subcapitata) to test substance ESA under static system for 72 hours are as follows.
The test was carried out according to OECD guidelines for the testing of chemicals Test No. 201, "Freshwater Algae and Cyanobacteria, Growth Inhibition test" (Adopted 23 March 2006) and National Institute of Environmental Research Notification No. 2010-29 (16 August 2010) Regulations on designation of test institute for examination of toxicity of chemicals, etc. annex 5 chapter 2 clause 1 Algae growth inhibition test.
The test was performed using a control, a solvent control and concentrations of 4.0, 5.0, 6.3, 7 .9 and 10.0 mg/ L(nominal concentration, geometric series 1.26). Each geometric mean of test substance during the test period (0-72 hours) was 3.412, 4.431, 5.585, 7.272 and 9.068 mg/L (85.3, 88.6, 88.7, 92.0 and 90.7 % of nominal concentrations)
95 % confidence limits
1. Median Effect Concentration, Based on Measured Concentration
2. No Observed Effect Concentration, Based on Measured Concentration
3. Lowest Observed Effect Concentration, Based on Measured Concentration
Abnormal appearances were not observed in negative control group, solvent control group and test substance treatment group during the test period.
The mean of temperature was 22.5 ± 0.1 °C (min 22.4 - max 22.5).
The mean of pH was 7.70 ± 0.23 (min 7.28 - max 8.31).
The average light intensity of incubator was 6.186 ± 495 Lux (min 5,560 – max 6,930).
