I. SUMMARY
The acute toxicity of FH 3820 to the alga, Seleoastcum capricomutua, is described in this final report. The test was conducted for 3H Conpany for 96 hours during April 29 to May 3, 1991, at the EnviroSysteas Division of Resource Analysts, Inc. in Hanpton, Hew Hanpshire. It was conducted by Jeanne Hagazu, Peter Kowalski, Ellen Stanford, Robert Boeri, and Tiaothy Ward.
The test was perforaed under static conditions with five concentrations of test substance and a dilution water control at a mean teaperature of 23.0C. The dilution water was synthetic aedia prepared with sterile deionized water. Flasks were incubated on a rotary shaker. Light was adjusted to 40 uEin/sec/a* with a photoperiod of 24 hours light and 0 hours dark. Noninal concentrations of FH 3820 were: 0 ag/L (control), 62.5 ag/L, 125 ag/L, 250 ag/L. 500 ag/L, and 1,000 ag/L. Koainal concentrations were used for all calculations.
Algae used in the test was froa an in-house culture that was aaintained under test conditions. Exposure of algae to the test substance resulted in a 72 hour EC50 284 ag/L FH 3820 and a no observed effect concentration (HOEC) less than 62.5 ag/L. The 96 hour EC50 and H0EC are 255 ag/L and 125 ag/L, respectively.

it. introduction
This study was sponsored by 3H Company, St. Paul, Minnesota. The objective of the study was to determine the acute toxicity of FH 3820 to a freshwater alga. The report contains sections that describe the nethods and Materials employed in the study, and the results of the investigation. The report also contains an appendix that presents the water quality data collected during the test.
TEST SUBSTANCE:
T. METHODS AND MATERIALS
FM 3820 (EnviroSystems Sample Number 2696E) was delivered to EnviroSystems on November 15, 1990. It was contained in a 250 mL glass bottle that was labelled with the following information: "H 2864-6, FM 3820". FM 3820 {a pale yellow liquid) was supplied by 3M Company, 935 Bush Avenue, St. Paul, Minnesota. Prior to use the test material was stored in the dark at room temperature. A reserve sample (approximately 1.0 grams) will be archived at EnviroSystems for a minimum of 10 years.
DILUTION HATER:
Hater used for acclimation of test organisms and for all toxicity testing was sterile enriched media (O.S. EPA, 1978) with a pH of
approximately 8.0. Results of chemical analysis of a representative sample of deionized water used to prepare the media are presented in Table 1.
TEST ORGANISM:
Algae used for the test was from a culture originally procured from the Culture Collection of Algae at the University of Texas at Austin and
delivered to Envirosystens on April 12, 1990. The identity of the culture was verified using an appropriate taxonomic key. The culture was
transferred to sterile enriched media identical to media used for this test and maintained at test conditions.
TOXICITY TESTING:
The definitive toxicity test was performed during April 29 to Nay 3, 1991. It is based on procedures of the OECD (1984). The test was
conducted at a target tenperature of 22 i 2C with five concentrations of test substance and a dilution water control. A 1,000 mg/L stock solution
was- prepared in dilution water. The stock solution was added directly to dilution water contained in the test vessels without the use of a
solvent. Nominal concentrations of the test material were: 0 ug/L (control), 62.5 mg/L, 125 mg/L, 250 mg/L, 500 mg/L, and 1,000 mg/L.

Algae was randomly and equally distributed aaong three replicates of each treatment at the rate of 10,000 cells/al. The test was performed in 250 ml glass Erlenaeyer flasks that contained 100 al of test solution. The flasks were capped with inverted glass beakers. Test vessels were randoaly arranged on a rotary shaker in an incubator during the 96 hour test (a randoa numbers table was used to select the location of each vessel). A 24 hour light and 0 hour dark photoperiod was aaintained with cool-white fluorescent lights that provided a light intensity of 40 uEs-1m~1.
The number of algal cells/al in each test vessel was determined visually every 24 hours by Beans of direct aicroscopic counts with a henacytoneter. The pH (Beckaan model pHI 12 aeter) was deterained in each test flask at the beginning and end of the test, and temperature (ASTH mercury thermometer) was aeasured and recorded daily in the incubator.
STATISTICAL METHODS:
Results of the toxicity test were interpreted by standard statistical techniques (Stephan, 1983). The binomial or moving average method was used by the author to calculate EC50 values using nominal concentrations of test substance. The HOEC was calculated using Dunnett's test, which includes a parametric one-way analysis of variance (AHOVA). The average specific growth rate was calculated as the natural log of the number of cells per ml at 96 hours minus the natural log of the number of cells per al at 0 hours divided uy the exposure period, The percent change from control is calculated by subtracting the saaple average specific growth rate from the control average specific growth rate, dividing that value by the average specific growth rate in the control and multiplying that value by 100. The percent change froa control was used to compute EC50 and N0EC values.

Biological and water quality data generated by the acute toxicity test are presented in Table 2 and Appendix A, respectively, and the percent of control and average specific growth rate information is presented in Table 3.
The 24, 48, 72, and 96 hour EC50s for algae exposed to lit 3820 are presented in Table 4. The 72 hour EC50 is 284 ng/L, and the 72 hour HOEC is less than 62.5 ng/L FH 3820. The 96 hour EC50 is 255 ng/L and the 96 hour HOEC is 125 ng/L.
