W hile product toxicity could not be conclusively correlated to th toxicity and concentration of individual components, m ajor contributors to product toxicity are believed to be the filmer, the foam er, butyl CarbitolTM , and DuponolTM ME (sodium laurylsulfate). Components likely to contribute less to product toxicity are ethylene glycol, tolyltriazole, sodium octylsulfate, and D l-w ater. Further toxicity testing of components and product formulations should enable better correlation between component and p>roduct toxicities.

Purpose The purpose of this study is to increase 3M 's knowledge of the environmental effects of LIGHT W ATERTM aqueous film forming foam and the individual components used to make the product. And, by understanding these effects, to minimize them through formulation changes. II. Background This study was undertaken in response to testing done by the German Army which was reported in "Investigations of Toxic Effects and Biological Degradability of Foam Extinguishing Agents in Wastewater" by Ekkehard Ising. The report, hereafter referred to as the "German Army Report", included data for 16 fire fighting materials, of which two were 3M 's FC-203 and FC-206. The 16 fire extinguishing agents were categorized as: 5 multi-range foam agents 6 film-forming foam agents 3 protein foam agents 1 film-forming fluorine-protein foam agent 1 special foam agent for deep-fry pan fires Environmental effects considered in the German Army Report were: 1. Acute toxicity to the marine photoluminescent bacterium Photobacterium phosphoreum using the Microtox system. The toxicity was expressed as E.C.10 and EC50, however, the exposure time is not clear from the German Army Repbrt and may have been 1 0 ,2 0 , or 30 minutes. Two multi-range foam agents were considered "highly toxic". Three multi-range foam agents and 2 film forming agents were found to be "toxic". Four film-forming, all 3 protein, the film-forming fluorine-protein agent, and the deep-fry agent were considered to have "low toxicity". FC-203 and FC-206 were in the "low toxicity" category. 2 . Algae cell multiplication inhibition test using Scenedesmus subspicatus as the test organism with an exposure time of 72 hours. Toxicity was expressed as EC 10 and ECso. All foam agents with the exception of two of the protein foam agents were "toxic" to algae. The two protein foam agents had weak toxicity to algae. Both 3M products were considered "toxic" to algae. 3. Acute toxicity to Daphnia magna after exposure for 24 hours. The toxicity was expressed as LC10 and LC , but the effect criterion was the organisms' loss of ability to swim and will be referred to as EC 10 and EC, in this report. All 5 multi-range foam agents, all film-forming agents except FC -206, and the deep-fry agent were "toxic" to -2- Ml Daphnia. One film-forming agent (FC -206), all three protein agents, and the film-forming fluorine-protein agent had "low toxicity" to Daphnia. FC-203: "toxic"; FC-206: "low toxicity". 4. Acute toxicity to Zebrafish {Brachydanio rerio) after exposure for 48 hours. The ------- criteria was death and the toxicity was expressed as L C 10 and LC50. Only two multi-range foam agents were "toxic" to fish. Three multi-range foam agents and two film-forming agents were "borderline toxic/weakly toxic". "Weakly toxic" were 4 film-forming agents, 2 protein foam agents, and the deep-fry agent. One film-forming agent and the film-forming fluorine-protein agent w ere "non-toxic". FC-203 and FC-206 were in the "weakly toxic" category. 5. Chemical Oxygen Demand (COD) and 5-day Biochemical Oxygen Demand (BOD 5) of a 3% solution of the test material in water. The ratio of BOD s to COD was used as a rating guideline, with a BOD 5/CO D ratio of 0.5 or less considered "insufficient biochemical degradation". Two multi-range agents and one film-forming agent (FC-206) were considered insufficiently degraded biochemically. The ratio for FC-206 was 0.35. One multi-range agent and one film forming agent (FC-203) were considered "probably insufficient" because their BOD s/COD ratios were 0.55. The 9 remaining agents were all sufficient with their B O D 5/C O D ratios ranging from 0.60 to 0.89. The data from the German Army Report for the two 3M products are summarized in the table below. The data for the Microtox, Zebrafish, COD, and BOD 5 tests seem to be "reasonable" and "self-consistent". The data are considered reasonable because they agree fairly well with data from previous 3M studies and are considered self-consistent because the FC-206 data are roughly half that of FC-203.

First, the German Army's algae data show essentially equivalent toxicity for our two products. One would expect more toxicity for FC-203 than for FC-206, as shown in the Microtox, Zebrafish, and Daphnia tests. However, higher toxicity by FC -203 than by FC-206 may not always be true. For example, there may be a component which is particularly toxic to algae, perhaps disrupting the photosynthetic process. Second, our PED for FC-203 indicates no effect to two algal species at concentrations up to 1,000 mg/L. While the two algal species on the PED are not the same as those in the German Army Report, they are all freshwater species and such a large difference in toxicity wouldn't be expected. One important limitation with the PED data is that it dates from 1974 and it has been impossible to verify the exact formulation of the sample used in those tests. For the Daphn/a data in the German Army Report, the difference between the FC-206 and FC -203 values seems large when considering the water content of the two formulations. Also, there is a considerable difference between the PED data.and the German Army data. Our PED has a 48-hr static Daphnia magna L C 50 of 1,600 mg/L, while the German Army Report has a 24-hr static Daphnia magna EC 50 is 430 mg/L. The PED data is quite old (1973) and the formulation of the test sample cannot be verified. There is a major difference between the PED data and the German Army data in that the PED data is the concentration which causes death to 50% of the Daphnia test population (LC 50) and the German Army value is the concentration which causes 50% of the test population to stop swimming (Effective Concentration = EC50). The German Army value is in fair agreement with recent results1 which show a 48-hr static Daphnia magna EC 50 of 229 mg/L. One thing that should be kept in mind when considering the toxicity data is that reproducibility and precision of toxicity tests can vary considerably from laboratory to laboratory and over time. However, the differences between the old data (circa 1974) and the more recent data is more likely due to changes in formulation rather than changes In test protocol or test species. At any rate, our primary interest should be the toxicity of our current products and we; should be concerned with having current, reliable data on our PEDs. III. General Comments The following general statements summarize the factors guiding this study. 1. The primary purpose of the environmental effects data is for internal use in evaluating formulations and ingredients and not intended for submission to governmental regulatory authorities. Therefore, any testing should be done using low-cost, non-GLP methods. An exception may be data for the new foamer (L-4640) which may need to be submitted for the European PMN currently underway. 1 Draft Report from EnviroSystems Laboratory dated March 10,1991. W e have asked EnviroSystems to repeat the Daphnia tests for FC-203 and VW 160390. The preliminary results from EnviroSystems on the rest of the samples were acceptable. -4- o o iis ^ : 2. The German Army performs its own testing and no authority other than the German Army is presently using the evaluation scheme used in the report cited above. Therefore, there is no need to choose a laboratory, test protocol, or test species applicable only to the German Army test scheme. Instead, test methods and species ~~ should be chosen so that test results can be used in as many countries as possible. 3. W here possible, data on the environmental effects of components should be obtained from the literature or from raw material suppliers in order to reduce testing costs and tim e. 4. The National Institute of Occupational Safety and Health (NIOSH) terminology for the relative toxicity of the components and the formulations will be used in the discussion of toxic effects. While these terms were not used in the German Army Report, they are generally accepted in the US. The toxicity and corresponding terms are: Concentration Acutely Toxic to Test Population NIOSH Terminology <1 mg/L 1 - 1 0 mg/L 10 -1 0 0 mg/L 1 0 0 -1 ,0 0 0 mg/L >1,000 mg/L "Highly Toxic" "Moderately Toxic" "Slightly Toxic" "Practically Non-Toxic" "Insignificant Toxicity" ^ ' : ** 5.

Hems 14 to 16 were given to the author by Roger Aim (2/4/91). IV. Conclusions and Recommendations In order to correlate the toxicity of the product to the toxicity of individual components, the component concentration is taken into consideration. In the table-below, the toxicity to Daphnia of the pure components are given in the third column. The fifth column contains estimated toxicities based on product formulation. This is the toxicity which would be expected when the component is diluted in water to the same concentration as in the product. For example, one would expect that since the toxicity of pure butyl Carbitol is about 700 mg/L, the toxicity of a solution made of 35% butyl Carbitol and 65% water would have a toxicity of about 2 ,000. Some interesting observations can be made from these numbers. First, even though tolyl'triazole is quite toxic, it is present at low concentration in the product and when diluted in the product it probably does not contribute substantially to product toxicity. However, this analysis does not exonerate tolyltriazole as a major contributor to product toxicity. Second, the lowest numbers in the fifth column indicate components which will be the most likely contributors to product toxicity: butyl Carbitol, Duponol ME (dodecylsulfate), the foamer, and the filmer. Unfortunately, there is not a single component which stands out with a number in the fifth column which is substantially lower than all the rest. This may mean that there is a synergistic effect between components. -6- 00118$ Summary of Recent Daphnia Toxicity Data Hem Name 1. Ethyleneglycol (R M 3017) 2. Butyl Carb'rtol* (R M 8887) 3.

Environmental Effects Literature Search Data from previous 3M Environmental Laboratory Studies and from the literature are summarized in this section. Toxicity data noted by "AQUIRE" were obtained from a search of the USEPA AQUIRE database on Feb. 12 ,1 9 9 1 . Included as part of the reference for the data from AQUIRE are the date of publication of the original journal article and the review code established by a group of EPA reviewers. The reviewers have ranked toxicity data from the literature by the following scale: 1. Meets all review criteria. 2. Procedures generally satisfactory. 3. Insufficient in some area of the test methodology or test report. 4. Abstract or foreign paper with data in limited format. The complete contents of the AQUIRE database for each chemical is not given in this report because the database includes many obscure species of little interest (opossum shrimp, Indian catfish, snakehead catfish, oysters, clams, sponges and many others) and data which is considered by the EPA reviewers to be of questionable value. Additional degradability and toxicity data have been taken from the Handbook of Environmental Data on Organic Chemicals by Karel Verschueren (Nostrand Reinhold, New York, 1983). These are referenced by page number in the Handbook followed by the date of the original reference. There are many cases in which the same data appeared on AQUIRE and in Verschueren but only the AQUIRE reference is given because it includes the EPA quality rating of the original reference. Raw material suppliers were identified from the 3M PRISM database and suppliers were contacted and asked for any environmental data they have. Unfortunately, environmental data was not generally available from raw material suppliers. And, the suppliers were slow in sending the limited data do have. `' The source and reliability of the literature data was taken into consideration in the environmental assessment of the components and the recommendations for further testing. v Report Format; ' Information for each component or formulation is organized as follows: .

A BOD value should be obtained by our own BOD tests. This material is moderately toxic to fish, Daphnia, and algae. Our most recent Daphnia test data agrees well with literature data which gives us confidence in the contract laboratory's work on this material. Because there is sufficient fish toxicity data from the literature, no fish testing is warranted. Because of the algal toxicity shown in the literature data, algae testing should be done. Even though this material is toxic to a variety of aquatic organisms, it readily degrades and adverse effects will be minimal if it is passed through a wastewater treatment system or if a significant number of microorganisms are present in a natural water to degrade it rapidly. W e should do some studies in which our product is passes through a model wastewater treatment system and the measure the toxic effects of the model's effluent. Another study would be a simulation of a natural body of water using an aquarium stocked with fish. This would give us an understanding of the degradation in a river, pond, or lake. -: Recommendations for Additional Testing: BOD, COD, and Microtox. 4.

BOD and COD data should be obtained so that we have numerical values which have been obtained in tests comparable to those used for the remaining components. There is surprisingly little literature data available on the aquatic toxicity of this surfactant, however for the Daphnia data it shows considerably less toxicity than the C 12 surfactant. This surfactant is present at 3% so it may be a major factor to toxicity of the product. Fish, algae, and Microtox toxicity data are essential to complete the assessment of this ingredient.

Since the only difference between this material and FC -203 is tolyltriazole, testing this material along with FC -203 seem s like a good way to determine the effect of tolyltriazole. For the recent Daphnia data, there is little difference between FC-203 and V W 160390 and the effect of tolyltriazole cannot be seen. In fact, the toxicity of FC-203 was slightly less than the toxicity of V W 160390 in the recent EnviroSystems work. Since EnviroSystems is repeating the Daphnia for these two samples, we will have to wait until EnviroSystems has completed these tests before making an evaluation. ? 2. A Microtox and fish toxicity test should be done on this material and the results compared to the FC -203 results to see if there is a measurable effect caused by tolyltriazole in the product.

However, it has a low BOD/COD ratio and will contribute to a low ratio in the product. In addition, it shows considerable toxicity to algae. For these reasons, it would be best not to use this material in products unless no alternative can be found or its concentration in the product will be extremely low. The literature data is essentially complete for this material. Any4esting on this material must be reported to US EPA under section TSC A 8 (d). Recommendations for Additional Testing: None. 18.

The vendor for Triton X-305 (Rohm and H aas) has no data on the aquatic toxicity or biodegradability of Triton X -305. However, they are sending a datasheet on the aquatic toxicity of Triton X -100. Triton X -100 has a lower molecular weight than X -305 and they believe that the toxicity of X -305 is less than X -100 because X-305 is less surface active. Triton X -305 is not believed to degrade biologically. Rohm and Haas has recently sold their Triton product line to Union Carbide (1-800-752-1827) and will be transfem'ng the business in -the near future. The CAS number given by Rohm and Haas for the series is 9036-19-5. The following data is from A Q UIRE on this CAS number.
