- Preparation of test solutions
The standard test procedures required generation of test solutions that contain completely dissolved test substance concentrations or stable and homogeneous mixtures or dispersions. The testing of concentrations that disturbed the test system were prevented (e.g. film of the test substance on the water surface).
Hatcol 5127 is a light yellow liquid. The water solubi1ity of Hatcol 5127 at 20.4 +/-0.7°C was determined to be < 0.14x10^-3 g/l in a preliminary experiment (pH was between 8.0-8.1, NOTOX Project 388035).
AII test solutions with a loading rate at or above 1.0 mg/l were prepared separately (loading rates of 1.0, 10 and 100 mg/l). These saturated solutions were stirred for three days to reach maximum solubility. After the stirring period both the 10 and the 100 mg/l loading rates were inhomogeneous emulsions with a test substance floating layer, while the 1.0 mg/l loading rate was observed to be clear and colourless. Collection of the water phase by siphoning or centrifugation was not an option considering the specific gravity of the test substance (see also NOTOX Project 388035). After the stirring period all three mixtures/solutions were therefore filtered twice. First through a paper filter (Schleicher and Schuell 604) to remove the larger undissolved test substance particles (ca. > 5pm) and subsequent1y through a membrane filter (Schleicher and Schuell RC55, 0.45pm). Finally a ten-fold dilution was prepared from the filtrate prepared at a loading rate of 1.0 mg/1 and indicated as 0.1 mg/1. A11 test solutions were c[ear and colourless. Part of the test so1utions was used in the simultaneously performed acute Daphnia magna test (NOTOX Project 406979).

- Measures concentrations
The concentrations of Hatcol 5127 were determined by gas chromatography with mass spectrometric detection. The test substance consisted of a mixture of molecules with different molecular weights, which differed in water solubility, resulting in a number of peaks in the chromatogram of the test substance solutions. It was not possible to determine which molecule was responsible for the toxicological response, if any. Furthermore since not all components were quantifiable in the calibration chromatograms, it was not possible to determine the concentration of the total test substance. Therefore, the toxicological evaluation was based on the water soluble fraction at the loading rate. In addition, the actual concentration was estimated from the largest peak observed in the chromatograms of Hatcol 5127
Mortality and other effects.
No mortality or any other effects were observed.
Environmental conditions
AII test conditions remained within the ranges prescribed by the protocol (pH: 6.0-8.5, constant within 1 unit; temperature 20-24°C, constant within 2°C; oxygen > 60% of air saturation). - Results with reference substance (positive control):
- During the test the pH, oxygen concentration and the temperature of the medium were within the optimal ranges for fish.
Under the conditions of the present test PCP induced on lethal effects in carp at or below 0.22 mg/l. The 96h-LC50 for carp exposed to PCP was 0.32 mg/l (95 % confidence interval between 0.22 and 0.46 mg/l) and already reached within 24 hours of exposure. The range of the 96hLC50 for carp is generally between 0.10 and 0.46 mg/l based on historical data of reference tests performed approximately every 3 months from April 1988 until the end 2000, and annually since then. The response observed ln carp originating from the present batch falls within this range. - Sublethal observations / clinical signs:

- Validity criteria fulfilled:
- yes
- Conclusions:
- Under the conditions of the study Hatcol 5127 induced no visible effects in carp exposed to a filtered solution prepared at a loading rate of 100 mg/l, containing an average exposure concentration of 0.0093 mg/l (NOEC).
Due to the extremely low water solubility of Hatcol 5127, concentration levels that might be toxic to carp could not be reached. - Executive summary:
96-Hour Acute Toxicity Study in Carp with Hatcol 5127.
The study procedure described in this report was based on the ISO lnternational Standard 7346-1: Static method, 1996. ln addition, the procedures were designed to meet the test methods and validity criteria of the EEC directive 92/69, Part C.1, 1992, the OECD guideline No. 203, 1992 and the OECD series on testing and assessment number 23, December 14, 2000.
Hatcol 5127 is a light yellow liquid. The water solubility of Hatcol 5127 at 20.4 +/- 0.7°C was determined to be < 0.14x10^-3 g/l in a preliminary experiment (pH was between 8.0-8.1, NOTOX Project 388035).
AII test solutions with a loading rate at or above 1.0 mg/l were prepared separately (loading rates of 1.0, 10 and 100 mg/l). These saturated solutions were stirred for three days to reach maximum solubility. Collection of the water phase by siphoning or centrifugation was not an option considering the specific gravity of the test substance (see also NOTOX Project 388035). After the stirring period all three mixtures/solutions were therefore filtered twice. First through a paper filter to remove the larger undissolved test substance particles (ca. > 5pm) and subsequently through a membrane filter (0.45µm). Finally a ten fold dilution was prepared from the filtrate prepared at a loading rate of 1.0 mg/l. AII test solutions were clear and colourless.
A final test was performed exposing seven fish per concentration to a blank control, 0.45µm filtered solutions prepared at loading rates of 1.0, 10 and 100mg/l and in addition to a ten fold dilution of the filtrate prepared at a loading rate 1.0 mg/l for a period of 96 hours. Samples for analytical confirmation of actual exposure concentrations were taken from the blank-control and the highest test concentration at the start, after 24 hours of exposure and at the end of the test.
Since not all components of Hatcol 5127 were quantifiable in the calibration chromatograms, analytical results were based on the largest peak. Based on this peak the filtered solution prepared at a loading rate of 100 mg/l contained a mean initial concentration of 0.031 mg/l. After 24 hours the concentration was relatively stable at 0.024 mg/l (77% of initial) but after 72 hours of exposure this test concentration had decreased to below the lowest calibration solution (<0.001 mg/l). The average exposure concentration at a loading rate of 100 mg/l was calculated to be 0.0093 mg/l. The observed decrease after 24 hours of exposure was probably a consequence of the extremely low solubility.
The study met the acceptability criteria prescribed by the protocol and was considered valid. Hatcol 5127 induced no visible effects in carp exposed to a filtered solution prepared at a loading rate of 100 mg/l, containing an average exposure concentration of 0.0093 mg/l {NOEC).
Due to the extremely low water solubility of Hatcol 5127, concentration levels that might be toxic to carp could not be reached.
