After 24h stirring and 1-hour standing period, the 100 mg/L loading rate WAF solution was observed to remain a clear colorless water column in the mid-depth but with oily globules of test substance floating on the water surface. After siphoning, the microscopic inspection of WAF showed no micro-dispersions or undissolved test substance to be present.
Observation of test solutions
The blank control and the 100 mg/L loading rate WAF test solutions were observed to be clear and colorless during the test period.Intensity of illuminationAt the start of the test, the intensity of illumination of test environment was 70 lx, 90 lx and 106 lx (89 lx on average).At the end of the test, the intensity of illumination of test environment was 65 lx, 84 lx and 96 lx (82 lx on average).
Mortality
The cumulative mortality of blank control was 0% at the end of the test, which met the criterion for the validity of the test. At the end of the test, the cumulative mortality of the nominal loading rate of 100 mg/L WAF was 0%. So the 14 day threshold level of lethal effect of test substance was greater than 100 mg/L nominal loading rate WAF.
Observed abnormal response
At the end of the test, no abnormal responses were observed in blank control and the test substance group. So the 14 d lowest observed effect loading rate (LOEL) was greater than 100 mg/L nominal loading rate WAF. The 14d no observed effect loading rate (NOEL) was 100 mg/L nominal loading rate WAF.
Body weight and body length
The body weight and body length of 10 representative fish before the test were 0.144 g ± 0.016 g and 23.79 mm ± 0.99 mm respectively.The body weight and body length of all fish alive in blank control and the test substance group at the end of the test were 0. 146 g ± 0.017 g, 0.153 g ± 0.016 g and 24.48 mm ± 1.31 mm, 24.19 mm ± 1.65 mm, respectively.
Measurement of temperature, pH and dissolved oxygen of test solution
During the test, the measured values of pH and dissolved oxygen ranged from 7.76 to 8.29, and 80% to 101%, respectively. The temperature of test environment water ranged from 21.0 °C to 23.9 °C. The dissolved oxygen concentrations were kept at least 60 percent of the air saturation value, which met the criterion for the validity of the test.Determination of test substance concentration
Sample pre-treatment and preservation
50 mL test solutions were accurately taken and poured into the separating funnel, then 20 mL, 15 mL, 10 mL hexyl hydride were added respectively to extract for three times (5 min for each time). After that, extractions were collected and transferred into a 50 mL volumetric flask and then diluted with hexyl hydride to 50 mL.

Feeding: Fed with red worm once a day
Aeration: No aeration
Analysis of the actual concentration of test substance in test solution: The actual concentrations of 100 mg/L loading rate WAF test group were measured at 0d, 5d, 9d, 13d in the new solution and at 1d, 6d, 10d, 14d in the old solution by GC. The blank control were measured at 0d (new solution) and 1d (old solution).
Results
The measured concentrations of test substance in test solution: The results of the analytical methods are given in the final report of "Validation of an Analytical Method of NovaSpec Base Oil" (The report No. is A 14048-T14037-1R).
The measured concentrations of test substance in blank control were lower than the limit of detection (LOD = 0.863 mg/L) at 0d in the new solution and at 1d in the old test solution after the start of the test. The measured concentrations of test substance in 100 mg/L loading rate WAF were lower than the limit of detection (LOD = 0.863 mg/L) at 0d, 5d, 9d, 13d in the new solution and at 1d, 6d, 10d, 14d in the old solution.
14d threshold level of lethal effect: Greater than 100 mg/L nominal loading rate WAF
14d lowest observed effect loading rate (LOEL): Greater than 100 mg/L nominal loading rate WAF

Discussion
Due to the low aqueous solubility and complex nature of test substance, so according to the guidelines of "OECD series on testing and assessment number 23, Guidance Document on Aquatic Toxic Testing of Difficult Substances and Mixtures", the test substance solution was prepared as a Water Accommodated Fraction (WAF). During the test, the chemical analysis results showed that the measured concentration of 100 mg/L loading rate WAF was lower than the limit of detection of 0.863 mg/L. However, the test substance is a complex mixture, its toxicity cannot be attributed to a single component or a mixture of components, but to the test substance as a whole, the test results were based on nominal loading rate only.
No classification is applicable.

Additional information
A K1 GLP study was conducted in accoradance with OECD guidelines to assess the affects of chronic toxicity to Zebrafish (Danio rerio). The chronic toxicity of the test item to fresh water Zebrafish has been investigated and gave a 14 day Lowest Observed Effect Loading rate value > 100 mg/L loading rate WAF. The No Observed Effect Loading rate was 100 mg/L loading rate WAF. The substance did not demonstrate any significant toxicity to aquatic organisms, nor does it contain significant impurities that could effect the outcome of the a specific study.
