The criterion for effect was death. Results of the test are reported as a 96-hour LCS0 value (the concentration of test material estimated to be lethal to 50% of the test animals after 96 hours of exposure). All data related to this study are stored at BMRL. MATERIALS AND METHODS Test material The test material was recei: on 12 August 1981 in one 9.5-liter (&) cubetainer labeled|"3M SAMPLE 81-2/8."| The test material, 2 deep orange-yellow liquid, waf s or 55 re eceiv] ed: All test concentrations are reported here as milligrams (mg) of surfactant solution per % of seawater. or as parts per million (ppm) . . Test animals Mumnichogs were purchased from a commercial supplier and maintaine at BMRL in flowing, natural seawater for 15 days. During the 96-hour period immediately before the test, the salinity of the holding water was 27-28 parts per thousand (/oo) and the temperature was 21-22 degree: Celsius (C). period. No mortality was observed during the entire holding : The control fish were 27-35millimeters.(mm) standard length and 0.28-0.63 grams (g) wet weight; mean length and weight were 31 (S.D.%2) mm and 0.46 (S.D.:0.10) g, respectively. The control fish appeared to be representative of the test population. 0016777 2 Test water Water used to maintain and test the fish was natural seawater whic was pumped from Big Lagoon, a Gulf of Mexico estuary adjacent to BMRL. The pump intake was located about 80 meters (m) offshore at a depth of approximately 3 m. Water was pumped by a 316 stainless steel pump through hard polyvinylchloride (PVC) pipes, through sand-filled fiberglass filters, through charcoal-filled fiberglass filters, and through l0-micrometers (ym) pore size polypropylene core filters into an elevated fiberglass reservoir. Water was chilled by Teflon heat exchangers and flowed by gravity into the laboratory. Test conditions Methods for the 96-hour flow-through test were those described in BMRL's "Protocol for flow-through toxicity tests with fishes" dated 2 January 1980. The test was conducted in an intermittent-flow system by using a proportional diluter (Mount and Brungs, 1967) constructed to deliver 1 %/cycle/test aquarium at a dilution rate of 50%. The number of cycles was approximately 3.2/hour, except during day 3 when the @iluter cycled only 6 times in 24 hours because of a malfunction. The cycling rate of 3.2 ycles/hourprovided-approximatel 1.5 volume additions in 24 hours. v The surfactant stock solution (502,000 mg/%) was prepared by weighing 502 g of surfactant solution in a 1-2 volumetric flask and bringing to volume with deionized water. The stock solution was placed in a 4-% glass reservoir attached to a "dipping bird" (Mount and Brungs, 1967). A 15.5 milliliter volum of stock solution was delivered into the mixing cell via the dipping bird during each diluter cycle. A Teflon solenoid valve, controlled by float switches, regulated seawater flow into the water cells. Mixing of various 0016784 3 volumes of uncontaminated dilution seawater from the water cells with various volumes of stock solution in the test material cells produced the five concentrations of test material which were distributed to the appropriate test chambers. Test chambers were 30 centimeters (cm) x 30-cm x 91-cm glass aquaria which contained approximately 50 % of test solution or control seawater. Light was provided by two 3.7-m fluorescent blubs suspended 46 cm above the test containers, providing approximately 1100 lux incident to the water surface. Photoperiod was 12 hours of light and 12 hours of darkness. Five concentrations of surfactant solution and and a control were maintained. Selection of surfactant solution concentrations were based on the results of a 96-hour static test and a maximum test concentra- tion established by verbal authorization from Mr. Eric Reiner of the 3M Company. The nominal concentrations were 125, 250, 500, 1,000, and 2,000 ppm. To begin the test, the diluter cycled until all test chambers were filled with test solutions or control seawater. Ten fish were then placed into each duplicate test container. Survival of fish in all treatments was recorded at 24-hour intervals. The dissolved oxygen concentration and pH were measured in each test container at 0 and 96 hours and in both controls, low, middle, and high test solutions after 24, 48, and 72 hours of exposure The temperature and salinity were measured in both controls daily throughout the test. piluter function was checked daily by observation. Only one problem occurred. During the third day of exposure the diluter stoppe cycling shortly after the test was checked on a weekend. This problem ` 001679 4 however, did not result in any change in the test concentrations and therefore did not affect the validity of the test. : `The test was conducted 10-14 September 1981. RESULTS AND DISCUSSION After 96 hours of exposure to surfactarft solutions, mortality of fish ranged from 0% in test concentrations 1,000 ppm to 108 in the 2,000 ppm test concentration (Table 1). A 96-hour LC50 could not be calculated because mortality in the maximum test concentration was <508. Physical or behavioral abnormalitieswere observed onlyinthe 2,000 ppm test concentration. After 24 hours of exposure, 4 fish were observed to be darkerthannormal, however, this was observed again only after 96 hours when 1fishwasappadarrkeertnhat nnolrmy al. `After 72 hours of exposure, 11 fish were observed at the. surface of the water in the 2,000 ppm test concentration. This probably occurred because of the diluter malfunction and correspondingly low dissolved oxygenconcentrations. Mean salinity during the test ranged from 27-28 /oo. The temperature ranged from 22-27C; mean was 252C. The dissolved oxygen concentration remained >9% of saturation in all test containers through- out the exposure. Dissolved oxygen concentrations were low after 48 and72 hours ofexposure, especially in the 2,000 ppm test concentratior The low DO may have been caused by a high oxygen demand after 48 hours and thelacckh ofangeduoriv ngdeayr3. The pH was 7.4-8.0 in all test containers throughout the exposure (Appendix A). = 001650. 5 REFERENCES EG&G Bionomics Marine Research Laboratory. 1980.
