## Daphnia pulexACUTE STATIC-RENEWAL 48-HOUR DEFINITIVE TEST,

EPA-821-R-02-012 : SECTION 9, Method 2021 .

TEST OVERVIEW A 48-hour static-renewal toxicity test was conducted by Environmental Enterprises USA, Inc (EE USA) to determine toxicity of product (PR) Alfoterra 145-8S to Daphnia pulex neonates . Test organisms were cultured at EE USA and less than 24 .0-hours-old when this test was initiated . Reconstituted laboratory-prepared water was used as the diluent and a laboratory performance control was evaluated
. Five replicates of each control solution and five PR concentrations were prepared initially and renewed daily PR concentrations tested were 1, 2, 4, 8, and 16 mg/l . This test was initiated September 25, 2007, at 1650 and completed September 27, 2007, at 1649
. Methods, materials, and results are presented in this document . The test was conducted from September 25 - 27, 2007, at the laborato ry of EE USA . Those involved in pe rforming this test and in preparation of this repo rt were Veronica McNew, Mark A . O'Neil, and David L. Daniel . MATERIALS AND METHOD S Materials and methods for the work performed are stated in EPA-821-R-03-012 : Methods for Measuring the Acute Toxicity of EFFluents and Receiving Waters to Freshwater and Marine Organisms
. Actual materials and methods are detailed below . This test was performed with strict adherence to the requirements of EPA-821-R-03-012, Section 9, Method 2021 . Additionally, the recommendations and suggestions made elsewhere in EPA-821-R-03-012 were incorporated whenever applicable to optimize the experimental design
. D pulex was cultured and maintained in reconstituted moderately hard water at 20 + 1°C . Neonates were collected from approximately 300 adults selected from stock cultures and placed in a tempora ry holding vessel . Test organisms were not fed . Sensitivity of test organisms to a known toxicant was determined by performing an acute Standard Reference Toxicant (SRT) test, DP0710, with Potassium chloride (Sigma Chemical, Lot 096K0040) . The SRT test was initiated on September 26, 2007, with less than 24-hour old D. pulex neonates . Appendix F contains D
. pulex SRT control charts
.

48-hr LC50 : 781 mg/I Upper & Lower 95% Confidence Interval : 745 - 820 mg/I On September 7, 2007, the PR sample was delivered to EE USA. Test chambers were labeled with replicate identification and test chamber boards labeled with EE USA's project number. Six treatments, five PR concentrations, and a laboratory performance control, were prepared daily (Appendix A, page 1)
. Each treatment was poured into a new acid-washed 0 .5-gallon plastic container and placed in an environmental chamber to warm up to test temperature . After the test solutions reached test temperature, initial water quality parameters (dissolved oxygen (DO), conductivity, and temperature) were measured
. At the end of each 24-hour exposure period, prior to renewal, the ending DO, temperature, and pH in each treatment were recorded also (Appendix A, page 3) . Alkalinity and hardness were measured in the performance control solution, September 25 and September 26 (Appendix A, page 1)

Dear Mr. Russell: November 5, 2007

I have enclosed two (2) copies of the report "Evaluation of the Chronic Toxicity of the Alfoterra® Samples to the Freshwater Alga Selenastrum capricornutum". The results of our testing are as follows : Chronic Toxicity of the Water-Accommodated Fraction (WAF) of Alfoterra 145-8 The results of this test indicated that there were significant reductions in alg al growth at the 5,000 and 10,000 mg/L Alfoterra 145-8 (as WAF) concentrations. The algal growth NOEC was 2,500 mg/L ; the IC25 was 5,111 mg/L and the IC50 was 9,378 mg/L . Chronic Toxicity of the Water-Accommodated Fraction (WAF) of Alfoterra L167- 4 The results of this test indicated that there were significant reductions in algal growth at each of the tested Alfoterra L167-4 (as WAF) concentrations . The algal growth NOEC was <625 mg/L ; the IC25 was 970 mg/L and the IC50 was 1,662 mg/L . 

### Chronic Toxicity of the Water-Accommodated Fraction (WAF) of Alfoterra L167- 7 The results of this test indicated that there were significant reductions in algal growth at each of the tested Alfoterra L167-7 (as WAF) concentrations . The algal growth NOEC was <625 mg/L ; the IC25 was 1,549 mg/L and the IC50 was 2,632 mg/L . 

### Chronic Toxicity of Alfoterra 145-8 S The results of this test indicated that there were significant reductions in algal growth at the >2 mg/L Alfoterra 145-8S concentrations . The algal growth NOEC was 1 mg/L ; the IC25 was 1 . 2 mg/L and the IC50 was 1 .7 mg/L
. Chronic Toxicity of Alfoterra L167-4 S The results of this test indicated that there were significant reductions in algal growth at each of the tested Alfoterra L167-4S concentrations . The algal growth NOEC was <0 .5 mg/L ; the IC25 was 0 .25 mg/L and the ICSO was 0 .50 mg/L .

## An Evaluation of the Chronic Toxicity of the Alfoterra® Samples to the

Freshwater Alga Selenastrum capricornutum

1 . INTRODUCTION Sasol North America, Inc . (Sasol) has contracted Pacific EcoRisk (PER) to perform an evaluation of the chronic toxicity of six new Alfoterra® products (designated 145-8, L167-4, L167-7, 145-8S, L167-4S, and L167-7S) to algae . This evaluation consisted of performing the US EPA 96-hr algal growth test with the green alga Selenastrum capricornutum (note - this species was recently reclassified as Pseudokirchneriella subcapitata, but is still commonly referred to as Selenastrum capricornutum) . This report describes the performance and results of these tests . 

### 2 . CHRONIC TOXICITY TEST PROCEDURE S The method used in conducting these tests followed the guidelines established by the EPA manual "Short-Term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Freshwater Organisms, Fourth Edition" (EPA/821/R-02-013)
. 2 .1 Receipt and Handling of Sample s Sasol collected and shipped samples of six Alfoterra products (designated 145-8, L167-4, L167- 7, 145-8S, L167-4S, and L167-75) to the PER laboratory in Fairfield, CA . Upon receipt, these samples were stored at 4°C except when being used to prepare test solutions . 

### 2 .2 Preparation of Water-Accommodated Fractions (WAF ) Three of the Sasol products (145-8, L167-4, and L167-7) were known to be only sparingly soluble in water ; in order to test the potential toxicity of these compounds, water-accommodated fractions (WAFs) were prepared so as to evaluate the toxicity of any constituent chemicals that would partition into a water phase (and thus be able to cause toxicity to freshwater organisms)
. The WAFs were prepared by adding 20 .0 gm of chemical product to 2 .0 L of reverse osmosis, de-ionized (RO/DI) water (net concentration = 10 gm/L = 10,000 mg/L) in a 2-L+ glass beaker
. A Teflon-coated magnetic stir-bar was added to each beaker and the solutions mixed for -24 hrs on magnetic stir plates with a -25% vortex . Upon stopping the mixing, the materials separated out into 2 phases : water beneath and insoluble chemical product on top . Approximately 1800 mL of WAF solution was drawn from the bottom water phase of each beaker, and comprised the 10,000 mg/L (as WAF) solution for each chemical product.

2 .3 Algal Growth Toxicity Testing with Selenastrum capricornutu m The chronic algal toxicity test consists of a-96-hr bioassay in which the green alga Selenastrum rapricornutum is exposed to a series of product dilutions and the effects on cellular reproduction determined . The specific procedures used in this test are described below . The Lab Control/diluent for these tests consisted of reverse-osmosis, de-ionized (RO/DI) water
. Aliquots of the Lab Control water and sample were spiked with nutrients and then filtered (using sterile 0 .45 pm filters) before use in these tests, as per EPA guidelines . The nutrient-amended and filtered waters were then used to prepare test solutions at test treatment concentrations of : • 625, 1250, 2500, 5000, and 10,000 mg/L for the WAF testing, • 0 .5, 1, 2, 4, and 8 mg/L for 145-8S, and L167-7S, and • 0 .25, 0 .5, 1, 2, and 4 mg/L for L167-4S . Routine water quality characteristics (pH, dissolved oxygen [D .O .], and conductivity) were measured on these test solutions prior to their use in the test
. There were 4 replicates for each test treatment, each consisting of a 250-mL glass Erlenmeyer flask containing 100 mL of test solution ; an additional replicate was established at each test treatment for measurement of test solution water quality characteristics during the test and at test termination . Each flask was inoculated to an initial cell density of 10,000 cells/mL of Selenastrum from an ongoing laboratory culture that is maintained in log growth phase . These flasks were loosely capped and randomly positioned within a temperature-controlled room at 25°C, under continuous cool-white fluorescent illumination . Each replicate flask was gently shaken a minimum of 3 times daily . After 96 (±2) hrs exposure, the algal cell density in each replicate flask was determined by spectrophotometric analysis . The resulting cell density data were analyzed to evaluate any impairment of algal growth caused by the leachate ; all statistical analyses (e .g ., determination of the NOEC, LOEC, and key IC point estimates) were made using the CETIS® statistical software (Version 1 . 1 .2revL, TidePool Scientific, McKinleyville, CA) .

3 .5 Chronic Toxicity of Alfoterra L167-4S to Selenastrum capricornutunt The results of this test are summarized below in Table 5 . There were significant reductions in algal growth at each of the tested L167-4S surfactant concentrations . The algal growth NOEC was <0 .5 mg/L : the IC25 was 0 .25 mg/L and the ICso was 0 .50 mg/L . 

### Note -- During the final 24 hrs of testing of this material, a`film' of some type was observed to have developed on the surface of the 0 .25 mg/L test solutions . It was also observed that the visible algal growth that is typical of the final 24 hrs of this test was not evident ; this is reflected in the low algal cell density that was measured at this test treatment . Upon consultation with Sasol staff, it was hypothesized that the film may have been the result of microbial (or other) degradation of the product, with subsequent inhibition of light penetration into the test replicate test solutions . As a result of this artifactual interference, the results of this test treatment were not included in the statistical analyses of these test results . The test data and summary of statistical analyses for this test are presented in Appendix E .

## Daphnia pulex ACUTE STATIC-RENEWAL 48-HOUR DEFINITIVE TEST,

EPA-821-R-02-012 : SECTION 9, Method 2021 .

TEST OVERVIEW A 48-hour static-renewal toxicity test was conducted by Environmental Enterprises USA, Inc (EE USA) to determine toxicity of product (PR) Alfoterra L167-4S to Daphnia pulex neonates . Test organisms were cultured at EE USA and less than 24 .0-hours-old when this test was initiated . Reconstituted laboratory-prepared water was used as the diluent and a laboratory performance control was evaluated
. Five replicates of each control solution and five PR concentrations were prepared initially and renewed daily PR concentrations tested were 1, 2, 4, 8, and 16 mg/l . This test was initiated September 25, 2007, at 1707 and completed September 27, 2007, at 1655
. Methods, materials, and results are presented in this document . The test was conducted from September 25 - 27, 2007, at the laborato ry of EE USA. Those involved in performing this test and in preparation of this repo rt were Veronica McNew, Mark A . O'Neil, and David L . Daniel . MATERIALS AND METHOD S Materials and methods for the work performed are stated in EPA-821-R-03-012 : Methods for Measuring the Acute Toxicity of Effluents and Receiving Waters to Freshwater and Marine Organisms . Actual materials and methods are detailed below . This test was pe rformed with strict adherence to the requirements of EPA-821-R-03-012, Section 9, Method 2021 . Additionally, the recommendations and suggestions made elsewhere in EPA-821-R-03-012 were incorporated whenever applicable to optimize the experimental design . D pulex was cultured and maintained in reconstituted moderately hard water at 20±1°C . Neonates were collected from approximately 300 adults selected from stock cultures and placed in a tempora ry holding vessel . Test organisms were not fed . Sensitivity of test organisms to a known toxicant was determined by performing an acute Standard Reference Toxicant (SRT) test, DP0710, with Potassium chloride (Sigma Chemical, Lot 096K0040) . The SRT test was initiated on September 26, 2007, with less than 24-hour old D. pulex neonates . Appendix F contains D pulex SRT control charts
.

48-hr LC50- 781 mg/1 Upper & Lower 95% Confidence Interval : 745 - 820 mg/I On September 7, 2007, the PR sample was delivered to EE USA. Test chambers were labeled with replicate identification and test chamber boards labeled with EE USA's project number . Six treatments, five PR concentrations, and a laboratory performance control, were prepared daily (Appendix A, page 1)
. Each treatment was poured into a new acid-washed 0 .5-gallon plastic container and placed in an environmental chamber to warm up to test temperature . After the test solutions reached test temperature, initial water quality parameters (dissolved oxygen (DO), conductivity, and temperature) were measured
. At the end of each 24-hour exposure period, prior to renewal, the ending DO, temperature, and pH in each treatment were recorded also (Appendix A, page 3) . Alkalinity and hardness were measured in the performance control solution, September 25 and September 26 (Appendix A, page 1)

EPA-821-R-02-012 : SECTION 9, Method 2021 .

TEST OVERVIE W A 48-hour static-renewal toxicity test was conducted by Environmental Enterprises USA, Inc (EE USA) to determine toxicity of product (PR) Alfoterra L167-7S to Daphnia pulex neonates . Test organisms were cultured at EE USA and less than 24 .0-hours-old when this test was initiated . Reconstituted laboratory-prepared water was used as the diluent and a laboratory performance control was evaluated

. Five replicates of each control solution and five PR concentrations were prepared initially and renewed daily PR concentrations tested were 1 .9, 3 .8, 7 .6, 15 .3, and 30 .5 mg/I . This test was initiated September 25, 2007, at 1720 and completed September 27, 2007, at 1701
. Methods, materials, and results are presented in this document. The test was conducted from September 25 - 27, 2007, at the laborato ry of EE USA . Those involved in pe rforming this test and in preparation of this repo rt were Veronica McNew, Mark A O'Neil, and David L . Daniel . MATERIALS AND METHODS Materials and methods for the work performed are stated in EPA-821-R-03-012 : Methods for Measuring the Acute Toxicity of EFFluents and Receiving Waters to Freshwater and Marine Organisms

. Actual materials and methods are detailed below . This test was performed with strict adherence to the requirements of EPA-821-R-03-012, Section 9, Method 2021 . Additionally, the recommendations and suggestions made elsewhere in EPA-821-R-03-012 were incorporated whenever applicable to optimize the experimental desig n D pulex was cultured and maintained in reconstituted moderately hard water at 20 + 1°C . Neonates were collected from approximately 300 adults selected from stock cultures and placed in a tempora ry holding vessel . Test organisms were not fed . Sensitivity of test organisms to a known toxicant was determined by performing an acute Standard Reference Toxicant (SRT) test, DP0710, with Potassium chloride (Sigma Chemical, Lot 096K0040) . The SRT test was initiated on September 26, 2007, with less than 24-hour old D. pulex neonates . Appendix F contains D pulex SRT control charts

48-hr LC50 : 781 mg/I Upper & Lower 95% Confidence Interval : 745 - 820 mg/1 

### On September 7, 2007, the PR sample was delivered to EE USA . Test chambers were labeled with replicate identification and test chamber boards labeled with EE USA's project number . Six treatments, five PR concentrations, and a laborato ry performance control, were prepared daily (Appendix A, page 1) . Each treatment was poured into a new acid-washed 0 .5-gallon plastic container and placed in an environmental chamber to warm up to test temperature . After the test solutions reached test temperature, initial water quality parameters (dissolved oxygen (DO), conductivity, and temperature) were measured

. At the end of each 24-hour exposure period, prior to renewal, the ending DO, temperature, and pH in each treatment were recorded also (Appendix A, page 3) . Alkalinity and hardness were measured in the performance control solution, September 25 and September 26 (Appendix A, page 1)

Subject : Definitive Acute Toxicity Tests of Three Materials on Daphnia magna

and Pimephales promelas Dear Allen : We have completed the definitive, static-renewal, acute toxicity tests with the three materials sent to us by CONDEA Vista Company on August 10, 1999 . All three materials were tested with both Daphnia magna and Pimephales promelas (fathead minnow) The following table summarizes the test conditions for each species : Test Condition s Test Parameter , D~ • hnia ma rta • , PiMe ' faales romefas Age <24 hours <24 hour s Test Chambers 100-m1 glass beakers 500-ml glass beakers Dilution Water Hard Moderately Har d Volume per Replicate 70-80 ml 300 m l Number of Replicates 4 4 Organisms per Replicate 5 1 0 Test Temperature 20±1 `C 20±1 ° C Feeding None 0 1 ml brine shrimp @ 48 h ( 2 hours prior to renewal ) Test Duration 48 hours 96 hours Endpoint Mortality Mortality Test Concentrations Nominal Nominal Test Guidance ASTM 1998 Standard Guide for Conducting Acute Toxicity Test s on Test Materials with Fishes, Macro invertebrates, an d Amphibians Method E729-96, pp 218-238 In 1998 Annual Boo k of ASTM Standards, Vol . 11 05, Biological Effects an d Environmental Fate ; Biotechnology, Pesticides .

# ~ : 5 7 A Nielse n 24 September 1999 Page 2 Tests were renewed daily with test solutions prepared fresh each day . For the tests with D . magna, renewal solutions on Day 1 were prepared with the original stock solution prepared on Day 0 Day 0 stocks of 145-2PO-SO4 and 123-2PO-SO4 were also used to prepare the fathead minnow test solutions each day . However, because of the larger volume of 12-3POS04 needed to renew the fathead minnow tests, a fresh stock solution of this material was prepared dail y A summary of the test results is presented in the following table More detailed information on organism survival in each test is presented in the attached pages ,
