The recording chart for the test room indicates that the temperature dropped to <br /> approximately 18°C for several hours between 9 AM and 1230 PM on November 7, and dropped <br /> again during the morning hours of November 8, 1993. The temperature remained within <br /> acceptable limits during the rest of the 96 hour test exposure period. The temperature drop <br /> probably had no effect on the outcome of the test, because it was within one degree of the <br /> acceptable limits and occurred for a relatively short period of time during the test. <br /> RESULTS <br /> A review of survival data shows that there was 100% survival in the lab control at the end of the <br /> test. This result met the test acceptability criterion of at least 90% survival during the 96 hour <br /> exposure period. Representative control fish had a mean standard length of 11.5 mm (range <br /> 11.0 to 12.2 mm) and a mean wet weight of 0.0153 grams (range 0.0125 to 0.0180 grams). <br /> Test results for sample AC27217 are summarized in Table 2. <br /> A review of the survival data for Sample AC27217 shows that there was 100°% survival in the 750 <br /> mg/I, 500 mg/l, and 250 mg/I test treatments at the 96 hour exposure period. The results of this <br /> screening assay indicate that the LC50 is greater than 750 mg/I, and that the sample should be <br /> classified as not hazardous under the CCR Title 26 Section 22 criteria. <br /> Test results for sample AC27218 are summarized in Table 3. <br /> A review of the survival data for Sample AC27218 shows that there was 100% survival in the 750 <br /> mg/I and 500 mg/I treatments and 95% survival in the 250 mg/I test treatment at the 96 hour <br /> exposure period. The results of this screening assay indicate that the LC50 is greater than 750 <br /> mg/I, and that the sample should be classified as not hazardous under the CCR Title 26 Section <br /> 22 criteria. <br /> REFERENCES <br /> EPA, 1990.
