- Specific details on test material used for the study:
-
- SYLVATAL 25/30 (distilled tall oil)
- Stability under test conditions: Test article is a low soluble, at the test temperature, non volatile liquid. - Analytical monitoring:
- not specified
- Details on sampling:
- - Concentrations: Control, 625 mg/L, 1250 mg/L, 2500 mg/L, 5000 mg/L, 10000 mg/L
- Sampling method: The test was carried out with aqueous extracts (WAF = Water Accommodated Fraction) at various loading ratios in daphnia-medium. The extract was formed by stirring 5 various amounts of the test article in daphnia medium for 23 h with a magnetic stirrer. The extraction was carried out in glass beakers which were equipped with a glass tube, which allowed the separation of the water phase by siphoning. The endpoint of the test was therefore the LL50 (lethal loading). The mixing was done slow enough not to cause dispersion or emulsification of the undissolved test article. Therefore the developed vortex (by stirring) at the surface was not deeper than 10% of the water height. After stirring for 23 hours the solutions were allowed to stand for 1 hour before use in order to allow phase separation. The test was carried out in a static way and the pH was not adjusted. The extractions were clear. - Vehicle:

- Culture medium different from test medium: Culturing Medium: Stock solutions in demineralised water:
Synthetic sea salt (Wimex hwMeersaltz): 0.333 g/L
CaCl2 x 2H2O (117.6g/L): 2.3 mL/L
NaHCO3 (25.2g/L): 2.2 mL/L
SeO2 (1.4g/L): 0.1 mL/L
This water was aerated with oil free compressed air until saturation. The synthetic sea salt contained 7 macro nutrients, 60 trace elements, 8 vitamins and 3 amino acids. By addition of CaCl2 and NaHCO3, the total hardness (2.5 mmol/L, the Ca/Mg-relation (4:1) and the alkalinity (0.8 mmol/L) were adapted to the medium described in the OECD Guideline 202.
- Intervals of water quality measurement: pH, dissolved oxygen and temperature were measured at the start and end of the test.
OTHER TEST CONDITIONS
- Adjustment of pH: None
- Photoperiod: 14h light/10h dark (Gro-Lux)
EFFECT PARAMETERS MEASURED (with observation intervals if applicable): Observations were made 1-3 times per day, at least 0h, 24h and 48h.
VEHICLE CONTROL PERFORMED: no - Reference substance (positive control):
- no
- Duration:
- 24 h
- Dose descriptor:
- EL50
- Effect conc.:
- > 10 000 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mobility
- Key result
- Duration:
- 48 h
- Dose descriptor:
- EL50
- Effect conc.:
- > 5 000 - < 10 000 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mobility
- Validity criteria fulfilled:
- yes
- Conclusions:
- The test article SYLVATAL 25/30 shows toxic effects (EL50 96h) at nominal concentrations above 5000 mg/L.
The TOC values of the 1000 mg/L WAF show that only a small amount of fthe test article was dissolved (approximately 30 mgTOC/L).
The pH value indicates that the amount of test article used to prepare the WAF determines the acidity of the solution.
Referring the toxicity to the soluble parts of the test article (measured as TOC) an EC50 (48 h) of approximately 30 mg/L is obtained which means that WAFs gained with more than 5000 mg/L (loading) are acute toxic to daphnia while WAFs gained with ≤5000 mg/L don't show any negative effects. - Executive summary:
In a study according to OECD Guideline 202 (Daphnia sp. Acute Immobilisation Test) the test article SYLVATAL 25/30 shows toxic effects (EL50 96 h) at nominal concentrations above 5000 mg/L (Water Accomodated Fractions).

Five cladocera were allocated to each test beaker and each treatment was triplicated. The test duration was 48 hours and the temperature was kept constant with 16:8 hour light to dark regime.

- GLP compliance:
- not specified
- Specific details on test material used for the study:
- -Test substance name: Triethanolamine
- Source and lot/batch No.of test material: Not stated
- Purity: No data
- Storage: All components were stored in the dark at 22±2°C.
- Expiration date of the lot/batch: Not stated - Analytical monitoring:
- not specified
- Details on test solutions:
- Stock solutions of each component (except the enzymes), were made by dissolving the appropriate amount in 1 or 2 L of the water described previously and then gently stirred for 12 h in the dark at 23±1°C using Teflon magnetic stirrers. Stock solutions of the enzymes were made immediately prior to commencing the bioassays and were stirred for a maximum of 15 min. Stirring was conducted so that no bubbles were formed when the surfactants were dissolved, as the formation of bubbles leads to depletion of surfactants in the solution (Aboul-Kassim and Simoneit, 1993). Light was excluded during the stirring to minimize photodegradation of the chemicals. Stock solutions were diluted to the appropriate concentrations immediately prior to the commencement of a test.
