The Santicizer® 8 plasticizer test compound was received on January 7, 1983, in good condition. The sample upon receipt was observed to be a yellow liquid and was stored at 4°C. Sample purity was listed as >95%. Stability is recorded to be above 6 months and solubility in water as 13%. Test concentrations were prepared based on the total compound. - Analytical monitoring:
- no
- Vehicle:
- no
- Details on test solutions:
- The test concentrations were obtained by transferring appropriate weights of the compound directly to the test chambers.
- Test organisms (species):
- Lepomis macrochirus
- Details on test organisms:
- The bluegill sunfish used in the test were obtained from Fattig Fish Hatchery in Brady, Nebraska. The fish were identified to species using the taxonomic keys developed by (Eddy,1969). All test fish were held in culture tanks on a 16 hour daylight photoperiod and observed for at least fourteen days prior to testing. Fish culture techniques used were basically those described by Brauhn & Schoettger(1975). A daily record of fish observations during the holding period, along with any therapeutic diseases treatments were recorded.
During this period, the fish received standard commercial fish food (Rangen’s) daily until 48 hours prior to testing at which time feeding was discontinued. The bluegills sunfish used for this experiment had a mean weight of 0.49g and a mean standard length of 26mm. The test vessels were kept in a water bath at 22°C (±1.0). The test fish were acclimated to the dilution water and test temperature and held without food for 48 hours prior to testing. - Test type:

- TEST SYSTEM
The static fish bioassay was conducted in five gallon glass vessels containing 15 liters of well water. A 72 hour range-finding test was conducted to determine the concentration range for the definitive study. The preliminary test concentration was set at 100 mg/l. Based on the results of preliminary testing, five concentrations of the test compound, ranging in a logarithmic series from 100 to 1000 mg/l, with ten fish per concentration were selected for definitive bioassay. The fish were added to the test chambers by random assignment within 30 minutes after addition of test material aliquots. Mortality and abnormal effects were monitored and recorded once every 24 hours.

- Details on results:
- Water quality parameters of temperature, dissolved oxygen, pH and ammonia were measured throughout the test and were within acceptable limits outlined by the Committee on Methods for Toxicity Tests with Aquatic Organisms. Recorded dissolved oxygen ranged between 43% and 103% saturation at 22 degrees. It should be noted that under the used guideline, acceptable limits are considered to be above 40% whereas the OECD 203 guidelines specify a dissolved oxygen(DO) concentration of at least 60%. Although DO concentrations were above 60% in the controls, this was not the case for the other treatment groups after 96 hour, thus raising question to whether this had any impact on the final outcome. No mortality of fish in the control vessel were seen which fullfills a principle OECD validity criteria however there is no evidence that the concentration of the substance being tested has been satisfactorily maintained.
- Results with reference substance (positive control):
- The 96 hour LC50 for bluegill sunfish exposed to Antimycin A was 6.2Xl0^(-5) mg/l and was within the 95% confidence intervals reported in the literature (Berger et al, 1969).
- Reported statistics and error estimates:
- Statistical analysis of the concentration vs. effect data (generally mortality) was obtained by employing a computerized LC50 program developed by Stephan et al. (1977). This program calculated the LC50 statistic and its 95 percent confidence limits using the binomial, the moving average, and the probit tests. Three different methods of analyzing the data were used since not one method of analysis is appropriate for all possible sets of data that may be obtained. The method of calculation selected for use in this report was that which gives the narrowest confidence limits for the LC50 .

- Executive summary:
Fish acute toxicity was examined in a EPA guideline study (EPA 660/3 -75 -009) study under quality control. In this study 10 bluegill sunfish (Lepomis macrochirus) per concentration, were exposed to nominal concentrations of 100, 180, 320, 560 and 1000 mg/L under static conditions for 96 hours. The 24 hour, 48 hour and 96 hour LC50 values for Santicizer 8 Plasticizer were determined as 420, 240 and 130 mg/L respectively and are based on nominal concentrations. Results indicated a 96 hour, no observed concentration of 100 mg/L based on mortality and abnormal effects. As a quality check, the bluegill sunfish were challenged with a reference compound, Antimycin A. The estimated 96 hour LC50 and 95% confidence limits (C.I.) were within the 95% confidence limits reported in the literature, indicating that the fish were in good condition.
