Sampling and analysis
- Analytical monitoring:
- yes
- Remarks:
- TOC analysis
- Details on sampling:
- Analytical measurement was performed by TOC analysis and therefore only the sum of the carbon content of the test item could be measured this way. Samples were taken at the tested concentration level as well as from the control at the beginning and at the end of the renewal periods to justify that the test item is present in the test solution, since more accurate data cannot be provided by TOC.
Samples were taken from the test solution and the control solution. the samples were filled into the tubes and they were measured by the NPOC method without any dilution. The measured carbon contents of the test solutions were corrected with the measured values of the control samples.
Test solutions
- Vehicle:
- no
- Remarks:
- Reconstituted algal growth medium (OECD medium, according to OECD 201) was used as dilution water
- Details on test solutions:
- Test item formulation
Because the test item is poorly soluble in water, a test solution was prepared using a saturated solution method according to the Guidance Document on Aquatic Toxicity Testing of Difficult Substances and Mixtures, OECD No. 23.
A saturated test item solution (nominal loading rate of 100 mg/L) was prepared by dispersing/dissolving the amount of test item into the test medium (OECD Medium) two days before the start of the study. This solution was shaken for about 24 hours at approximately 30°C and then equilibrated for about 24 hours at approximately 20°C. The non-dissolved test material was removed by filtration through a fine (0.22 µm) filter to give the 100 % saturated solution.
As a Limit Test was carried out, further dilution of stock solution was not be performed.
Untreated Control
Algal growth medium (OECD Medium) was inoculated with algal cells (without test item) and was examined in parallel to the test item concentrations.
Test organisms
- Test organisms (species):
- Raphidocelis subcapitata (previous names: Pseudokirchneriella subcapitata, Selenastrum capricornutum)
- Details on test organisms:
- Species: Pseudokirchneriella subcapitata (formerly known as Selenastrum capricornutum)
Strain number: 61.81 SAG (identical strains: CCAP 278/4; UTEX 1648; ATCC 22662)
Source: The algae were supplied by the SAG: Collection of Algal Cultures, Inst. Plant Physiology, and University of Göttingen, GERMANY. Cultured under standardised conditions (see OECD 201) in the Ecotoxicological Laboratory of the CRO
Justification of species: The species of Pseudokirchneriella subcapitata used, being a fast-growing species, is convenient for culturing and testing and is a recommended species by relevant guidelines.
Breeding conditions: Stock cultures are small algal colonies that are inoculated onto agar regularly. These are transferred to fresh agar medium at least once every two months and are maintained under standardised conditions according to the test guidelines.
The pre-culture is intended to give a quantity of algae suitable for the inoculation of test cultures. The pre-culture was prepared with the OECD algal growth medium, incubated under the same conditions as the test and used when still growing exponentially, after an incubation period of three days. When the algal cultures contain deformed or abnormal cells, they were discarded.
Study design
- Test type:
- static
- Water media type:
- freshwater
- Limit test:
- yes
- Total exposure duration:
- 72 h
Test conditions
- Hardness:
- not reported
- Test temperature:
- Culture temperature was checked at the beginning of the experiment and each day thereafter in a flask filled with water, in the climatic chamber. In addition, water temperature was continuously measured (with a min/max thermometer) within the climate chamber. The temperature was in the range of 22.6 – 22.8 °C measured in the flask and between 22.1 and 23.4 °C measured within the climate chamber.
- pH:
- The pH was checked at the beginning and at the end of the test in each test vessels. The pH of the control medium was not increased by more than 1.5 units during the test. The range of the pH was 7.80 – 9.06 during the experiment.
- Dissolved oxygen:
- Measured concentration was below of the Limit of Quantification (LOQ = 5 mg Carbon/ L) both at the start and at the end of the experiment.
The biological results are based on the nominal test item concentration. - Salinity:
- not reported
- Conductivity:
- not reported
- Details on test conditions:
- Light Intensity
The algal culture flasks were continuously illuminated. The light intensity at the position occupied by algal culture flasks during the test was about 8358 lux (equivalent to ~113 microE/m2/s), which was ensured with fluorescent lamps (with a spectral range of 400-700 nm). The differences in light intensity between the test vessels were within 15 % (with the exception of only one case where the difference was 16.75 %, see Section 3.12.) and therefore provided equal conditions for each test vessel.
The test was started (0 hours) by inoculation of a biomass of approximately 10000 algal cells per mL test medium.
The test was performed with six replicates per test concentration and six replicates in the control group. Volumes of 100 mL test solution per replicate in 250 mL sterile Erlenmeyer flasks were continuously shaken by a laboratory orbital shaker to keep algae in suspension. The flasks were covered with air-permeable stoppers.
All procedures were performed under sterile conditions during the test.
The cell numbers were determined at 24, 48 and 72 hours after starting the test by manual cell counting using a microscopic method with a counting chamber.
Microscopic observation of the algal cells in each concentration and in the control was performed (at 24h, 48h and 72h) to detect any abnormal appearance of the algae. - Reference substance (positive control):
- yes
- Remarks:
- For the evaluation of the quality of the algae and validation of the experimental conditions, Potassium dichromate is tested at least twice a year to demonstrate satis factory test conditions.

Under the conditions of this algal growth inhibition test the calculated endpoints for the effect of Fir Needle Oil Canadian (Fir, Abies Balsamea, ext) were the following:
The 72h EbC50 value (biomass): > 100 mg/L nominal loading rate
The 72h ErC50 value (growth rate): > 100 mg/L nominal loading rate
The 72h EyC50 value (yield): > 100 mg/L nominal loading rate
The 72h No-Observed Effect Concentration (NOEC): 100 mg/L nominal loading rate
The 72h Lowest Observed Effect Concentration (LOEC): > 100 mg/L nominal loading rate - Executive summary:
The effect of Fir Needle Oil Canadian (Fir, Abies Balsamea, ext) test item was assessed on algal growth using the unicellular green alga Pseudokirchneriella subcapitata, over an exposure period of 72 hours.
Because a toxic response was not observed during the preliminary concentration range-finding test, a Limit Test was carried out using only one test concentration at the solubility level of the test item in the test medium (100 mg/L nominal loading rate, 100 % saturated solution) and one control group.
Analytical measurement was performed by TOC analysis and therefore only the sum of the carbon content of the test item was measured this way. Samples were taken at the tested concentration level as well as from the control at the start and at the end of the experiment. Measured concentration was below of the Limit of Quantification (LOQ =5 mg Carbon/ L) both at the start and at the end of the experiment.
The biological results are based on the nominal test item concentration.
The test design included six replicates at test concentration and six replicates for the untreated control.
Statistical comparisons of biomass, average specific growth rates and yield in control and in treated groups were carried out using 2 Sample t-Test (a= 0.05) by TOXSTAT software.
The ErC50,EbC50and EyC50values of the test item were determined directly from the raw data.
Under the conditions of this algal growth inhibition test the calculated endpoints for the effect of Fir Needle Oil Canadian (Fir, Abies Balsamea, ext) were the following:
The 72h EbC50value (biomass): >100 mg/L nominal loading rate
The 72h ErC50value (growth rate): >100 mg/L nominal loading rate
The 72h EyC50value (yield): >100 mg/L nominal loading rate
The72h No-Observed Effect Concentration (NOEC): 100 mg/L nominal loading rate
The72h Lowest Observed Effect Concentration (LOEC): >100 mg/L nominal loading rate
