2)25±1 °C - pH:
- 1) 6.8 ±0.3
- Nominal and measured concentrations:
- 1)Six test concentration were:
6.25mg/l, 12.5mg/l, 25mg/l, 50mg/l, 100mg/l and 200mg/l
2) 100 mg/l - Details on test conditions:
- 1.- No. of vessels per concentration (replicates):Two replicates for each test concentration
- No. of vessels per control (replicates):Three replicates for Control
-Test solution: The test solution was prepared in aseptic condition. The test item was prepared by adding 50 mg of test item in 250 ml of BBM to get the final concentration of 200mg/L. This stock solution was kept for stirring for 24 hours to obtain a homogenous solution for the experiment. The test concentrations were chosen according to the available data of the test item. The remaining test solutions were prepared by dilution from the above stock solution. To have a better growth and visibility of cells, the initial cell density of the culture was kept 1 X 104cells/ml. Care was taken to have a homogeneous solution for the experiment.
6.2. Test vessels: All the tests were carried out in 100mL conical flasks which were carefully autoclaved and sterilized. The test solution in each of these test vessels was kept constant which is 60ml so that a sufficient amount of head space was left.
6.3. Replicates: For the assessment of algal growth, the study was conducted in replicates. The control vessel was maintained in triplicates as recommended in the OECD guideline and the test concentrations were selected in geometric series which were maintained in duplicates.
Incubation:
i) The temperature of the orbital shaking incubator was kept constant throughout the period of exposure of the experiment. The temperature was maintained at 24 ° C±2°C.
ii) The test vessels were incubated with a continuous, uniform (1500Lux).
iii) The pH of the control cultures needs to be noted during the study and the pH of the control medium should not increase by more than 1.5 units during the test.
iv) The orbital shaking incubator was set at a speed of 120 revolutions per minute throughout the study period. This is to provide constant shaking to the algal cells to keep them in suspension and to ensure that they do not settle down on the bottom of the test vessel.
